The Chemistry of Explosions [2]
One more important section related to combustion is the “explosive” chemical. Explosives are substances that undergo a rapid oxidation reaction with the production of large quantities of gases.
The speed at which explosives decompose permits their classification as high or low explosives. The shock wave produced by the expanding gases causes much of the damage associated with an explosion.
Low explosives are those that burn only at their surface. This means that the burning of the compound follows a path
Reactions of Main Group Elements with Water [3]
Water is composed of two hydrogen atoms and an oxygen atom. It exhibits polarity and is naturally found in the liquid, solid, and vapor states
Because of its abundance on earth, it is important to note that it is involved in many chemical reactions. Many of these chemical reactions behave in trends that can be categorized using the periodic table.
This is represented by their large, negative electrode potentials. In this event, the Group 1 metal is oxidized to its metal ion and water is reduced to form hydrogen gas and hydroxide ions
The Dangers Of Water: How Water Can Cause Elements To Explode [4]
Water is made up of two hydrogen atoms and one oxygen atom, so when it comes in contact with other elements, it can cause them to explode. The most common elements that explode when they come in contact with water are sodium, potassium, chlorine, and magnesium
Their discovery has led them to a better understanding of how such a massive explosion could occur in such a small amount of time. They are described in the journal Nature Chemistry on January 26
As positively charged metal atoms move away from each other, the charge of the negatively charged atom moves away. A single atom contains a tiny fraction of a substance that contains over a hundred atoms

Why metals have a blast in water [6]
High-speed cameras now show why some metals explode when they get wet. It’s a classic chemistry experiment: A begoggled teacher drops a bit of metal into water — and KABOOM! The mixture explodes in a bright flash
The experiment only works with elements that are alkali metals. These elements show up in the first column of the periodic table
And that’s because on their own, they’re very reactive. So they easily undergo reactions with other materials
Which Elements When Placed In Water Produces An Explosion? [7]
Which Elements When Placed In Water Produces An Explosion??. For decades science enthusiasts have delighted at the famously energetic way sodium and potassium explode on contact with water.Jan 27 2015
The alkali metals (Li Na K Rb Cs and Fr) are the most reactive metals in the periodic table – they all react vigorously or even explosively with cold water resulting in the displacement of hydrogen.. |Explosives Based on Nitrogen||Ammonium nitrate (AN)|
Hydrogen is the most abundant element in the universe and the third most abundant element on Earth and occurs mainly in compounds such as water. 5: Potassium is a soft silvery metal that ignites explosively in water.

Reactions of the Group 1 elements with water [9]
This page looks at the reactions of the Group 1 elements – lithium, sodium, potassium, rubidium and caesium – with water. It uses these reactions to explore the trend in reactivity in Group 1.
In each case, a solution of the metal hydroxide is produced together with hydrogen gas.. This equation applies to any of these metals and water – just replace the X by the symbol you want.
Lithium’s density is only about half that of water so it floats on the surface, gently fizzing and giving off hydrogen. It gradually reacts and disappears, forming a colourless solution of lithium hydroxide
Sodium catches fire when it comes in contact with water because: [10]
Sodium catches fire when it comes in contact with water because:. The reaction of sodium metal with water is highly heat producing due to which the hydrogen gas formed during the reaction catches fire and burns causing little explosions.
The reaction of sodium metal with water is highly heat producing due to which the hydrogen gas formed during the reaction catches fire and burns causing little explosions.
Water-reactive substances [11]
Water-reactive substances[1] are those that spontaneously undergo a chemical reaction with water, as they are highly reducing in nature.[2] Notable examples include alkali metals, lithium through caesium, and alkaline earth metals, magnesium through barium.. Some water-reactive substances are also pyrophoric, like organometallics and sulphuric acid, and should be kept away from moisture
Such substances are classified as R2 under the UN classification system and as Hazard 4.3 by the United States Department of Transportation. In an NFPA 704 fire diamond’s white square, they are denoted as “W̶”.
The alkali metals (Li, Na, K, Rb, Cs, and Fr) are the most reactive metals in the periodic table – they all react vigorously or even explosively with cold water, resulting in the displacement of hydrogen.. The Group 1 metal (M) is oxidised to its metal ions, and water is reduced to hydrogen gas (H2) and hydroxide ion (OH−), giving a general equation of:
Sodium’s Explosive Secrets Revealed [12]
It’s the classic piece of chemical tomfoolery: take a lump of sodium or potassium metal, toss it into water and watch the explosion. Although this piece of pyrotechnics has amazed generations of chemistry students, until now it has been misunderstood, a paper in Nature Chemistry reveals.
That may happen eventually, but it begins as something far stranger: a rapid exodus of electrons followed by explosion of the metal driven by electrical repulsion.. The neurologist and celebrated author Oliver Sacks, who is also a chemistry enthusiast, described the phenomenon as “chemistry with a vengeance” in his book Uncle Tungsten
In bulk, sodium is a silvery metal, a soft solid at room temperature. If it comes in contact with water, it produces sodium hydroxide and hydrogen
The Reaction of Sodium in Water [13]
In this tutorial, you will learn about the reaction between sodium and water, what causes it and how it works.. When you wet a piece of sodium metal, it gets hot and fizzes; sometimes the reaction can be extreme enough to produce flames and explosions
So what about sodium itself causes such a violent reaction? The answer has to do with the quantum interactions between the metal and the water molecules.. It can be a little easier to understand this reaction when you think of sodium compared to a noble gas; it is similar to neon, which has ten protons and ten electrons
This stability is ruined when you detour from noble gases, such as with sodium. This element has 11 protons, and the ‘extra’ electron is held on very loosely with the next atomic orbital
Sodium and water react, and quantum physics explains why [14]
Sodium and water react, and quantum physics explains why. – Take a chunk of sodium metal and get it wet, or drop it in water, and not only does it fizz and give off heat, but it can even produce flames and explosions.
– It has everything to do with ionization energy, and how easy it is for sodium to lose an electron compared to water, hydrogen, or oxygen. It’s a little bit paradoxical: when we encounter something unexpected for the first time, we wonder why it happens that way
Drop a salt crystal — simple sodium chloride — into water, and it just dissolves.. Drop some chlorine into water, and you can disinfect it: killing bacteria, viruses, and other disease-causing microorganisms present within.
Alkali metals – the camera lies [15]
Declan Fleming explains how Brainiac’s faked explosions helped produce a great resource to stretch his students. What demonstration do you use to teach group relationships in the periodic table? What reaction shows the similarity of elements in a group and also the progressive chemistry from one element to the next?
It’s been nearly ten years since the appropriately titled Sky TV programme, Brainiac: Science Abuse, inadvertently kick-started the first real mainstream discussion on the alkali metals that chemistry teachers could widely participate in. YouTube had launched the previous year and domestic internet access speeds were just about making the widespread hosting and sharing of video clips practical
Brainiac had broadcast dramatic footage of alkali metals exploding in water. But with so many people now able to review and scrutinize the show, suspicions that the explosions had been faked were soon raised and then confirmed.
Reactions of alkali metals with water [16]
The Group 1 elements, also known as the alkali metals, all react vigorously with water to produce an alkaline solution.. All the alkali metals react vigorously with cold water
The speed and violence of the reaction increases as you go down the group. This shows that the reactivity of the alkali metals increases as you go down Group 1.
It fizzes steadily and becomes smaller, until it eventually disappears.. When sodium is added to water, the sodium melts to form a ball that moves around on the surface

Potassium reacts with water to produce _____ flame. [18]
Potassium reacts with water to produce _____ flame.. Hint: As we know that potassium is an alkali metal and very reactive in nature
This metal moves around quickly on the water and spreads the fire everywhere. So here we have to tell what type of flame gets produced when potassium reacts with water.
Potassium: It is a chemical element denoted by the symbol ‘K’ and has atomic number 19. It is a silvery-white metal which is so soft enough to be cut with a knife just by a little force
Explosive Reaction of Hydrogen and Oxygen Using Balloons [19]
Six balloons are filled with different gases and ignited. Different intensities of sound are emitted, with the loudest sound occurring when a hydrogen/oxygen mixture is ignited.
When ignited, hydrogen gas combines with oxygen gas explosively in proportions ranging from 4.1 – 71.5% hydrogen – ignition temperature is ca. This exothermic reaction yields 232 kJ/mol of water formed
When pure hydrogen is ignited, the reaction with the surrounding air is less rapid, the sound is less loud, and a significantly larger flame is produced. The comparatively mild sounds emitted when the helium balloons are ignited are caused by the rupturing of the balloons and the escape of the gas
What reaction takes place between Cesium and water that makes it react so violently? [20]
What reaction takes place between Cesium and water that makes it react so violently?. Cesium reacts with cold water to form hydrogen gas and a solution of cesium ions and hydroxide ions.
The sublimation energy (1) is the smallest of the alkali metals because the Cs atoms are the biggest.. As the atoms get bigger, the strengths of the metallic bonds decrease
The ionization energy (2) is the smallest of the alkali metals.. As you go down the Group, the valence electron is further from the nucleus and is screened by more layers of inner electrons.
Information on Alkali Metals – Stanford Environmental Health & Safety [21]
In their pure forms, the alkali metals (lithium, sodium, potassium, rubidium, and cesium) are soft, shiny metals with low melting points. Due to their reactivity, special precautions must be taken when using and storing these metals.
Alkali metals react with air to form caustic metal oxides. The heavier alkali metals (rubidium and cesium) will spontaneously ignite upon exposure to air at room temperature.
The heat produced by this reaction may ignite the hydrogen or the metal itself, resulting in a fire or an explosion. The heavier alkali metals will react more violently with water.
What Metals React With Water to Produce Hydrogen? [22]
Most alkali metals and alkaline earth metals react with water to produce hydrogen. The alkali metals comprise Group 1 of the periodic table, and include lithium, sodium, potassium, rubidium, cesium and francium
Beryllium, however, does not react with water, and francium is much too rare and unstable to be relevant to this question. When mixed with water, the alkaline earth metals generally produce a weaker reaction than the alkali metals.
Lithium’s reaction with water is relatively slow and gentle, because its density is roughly half that of water. It fizzes on the water’s surface, releasing hydrogen and gradually forming a clear lithium hydroxide solution.
