Concept explainers
Interpretation:
If the chemical equation Na + S → Na2S is balanced correctly, then the correct sequence of coefficients has to be chosen from the given options.
Concept Introduction:
Statement that uses chemical symbols and formulas instead of words in order to describe the changes that takes place in a
- Correct formulas of the reactants are written in left side of chemical equation.
- Correct formulas of products are written in right side of chemical equation.
- An arrow is placed between reactants and products which point towards the products.
- If two or more substances are present in reactant and product, plus sign is used to separate them.
Balanced chemical equation is the one that has equal number of atoms of each element that is involved in the chemical reaction on both sides of the chemical equation. An unbalanced chemical equation can be balanced by adding coefficients to the equation. It is a number that is placed in left side of the chemical formula so that it changes the amount only and not the identity.
