Shrimp gumbo is one of many dishes that are part of the Cajun culture in Louisiana. It’s a spicy dish that needs careful control of all the ingredients so that it has a “kick”, but is not overwhelming
Similarly, we need this type of information in order to carry out chemical reactions successfully and safely.. Word equations are time-consuming to write and do not prove to be convenient for many of the things that chemists need to do with equations
The chemical equation for the reaction of methane with oxygen is shown:. \[\ce{CH_4} + \ce{O_2} \rightarrow \ce{CO_2} + \ce{H_2O}\nonumber \]

Which of these laws (if any) do the following statements illustrate? (a) Lavoisier found that when mercury(ll) oxide, HgO, decomposes, the total mass of mercury (Hg) and oxygen formed equals the mass of mercury(ll) oxide decomposed. (b) Analysis of the calcium carbonate found in the marble mined in Carrara, Italy, and in the stalactites of the Carlsbad Caverns in New Mexico gives the same value for the percentage of calcium in calcium carbonate
With the advent of techniques such as scanning tunneling microscopy, it is now possible to write with individual atoms by manipulating and arranging atoms on an atomic surface. If an image is prepared by manipulating iron atoms and their total mass is 1.05 1020 g, what number of iron atoms were used? b
What is meant by the skeletal chemical Equation [5]
Answer- A skeletal equation is an unbalanced equation. In this unbalanced equation, the number of atoms of the elements on the reactant side does not match with the number of atoms of the same element on the product side
The law of conservation of mass is responsible for the balancing of chemical equations. A skeletal chemical equation does not abide by the law of conservation of mass.
These equations do not reveal the type of reactions taking place in an equation. The state of the reactants and the catalyst is unknown in a skeletal equation.
Skeleton Equation: Definition & Examples [6]
Have you ever heard of gold cyanidation? An aqueous cyanide solution is used to treat crushed gold ore in the presence of air, forming a soluble gold compound, which can then be further reduced to recover pure gold.The skeleton equation for this reaction is given as: \( \text{Au} \text{ + NaCN + } \text{O}_{2} + \text{H}_{2}\text{O} \longrightarrow \text{Na(Au(CN)}_{2}) + \text{NaOH}\).

\( \text{Au} \text{ + NaCN + } \text{O}_{2} + \text{H}_{2}\text{O} \longrightarrow \text{Na(Au(CN)}_{2}) + \text{NaOH}\).. But what does this mean? Let’s explore what skeleton equations are!

It means that what is on the left side of the equal sign is equal to what is on the right side of the “=”.. A chemical equation is a way to represent a chemical reaction
Instead of an equal sign, an arrow is drawn between the reactants and the products. It is important to note that the arrow does not mean the same thing as an equal sign
State the limitations of a balanced chemical equation. [8]
State the limitations of a balanced chemical equation.. Hint: A symbolic representation of a chemical reaction which has an equal number of atoms of each element in the product and the reactant is known as a balanced chemical equation
We know that the chemical reactions are represented by the balanced chemical equations. The reacting species are written on the left side of the balanced chemical equation while the product species are written on the right side of the equation.
$2{{\text{H}}_2} + {{\text{O}}_2} \to 2{{\text{H}}_2}{\text{O}}$. The balanced chemical equation represents the reaction of formation of water from hydrogen and oxygen.

Making sure they are balanced must be done before the equation can be used in any chemically meaningful way.. All chemical calculations you will see in other units must be done with a balanced equation.
The Law of Conservation of Mass is the rationale for balancing a chemical equation. The law was discovered by Antoine Laurent Lavoisier (1743-94) and this is his formulation of it, translated into English in 1790 from the Traité élémentaire de Chimie (which was published in 1789):
