Question

From a complete and correctly written chemical equation, you can obtain the

a.chemical formulas of the reactants and products.
b.relative amounts of the reactants and products.
c.physical states of the reactants and products.
d.All of the above

Answer 1

A balanced chemical equation provides the mole ratio of reactants to products, obeys the law of conservation of matter, and indicates the correct proportions for the chemical reaction.

Step-by-step explanation:

From a complete and correctly written chemical equation, you can obtain a wealth of information. A balanced chemical equation reflects the law of conservation of matter, ensuring that the number of atoms for each element is the same on both sides of the equation. This balance implies the mole ratio of reactants and products, which is essential for stoichiometric calculations.

The coefficients in front of the chemical formulas indicate the relative amounts of each substance involved in the reaction. By understanding these coefficients, you can determine the proportions in which reactants combine and the amounts of products formed. It's crucial to remember that in a reaction, elemental gases like hydrogen (H2) and oxygen (O2) are diatomic, as reflected in their chemical formulas. For example, the reaction between hydrogen and oxygen to form water is expressed as 2H2 + O2 → 2H2O, where it's understood that two molecules of hydrogen gas react with one molecule of oxygen gas to produce two molecules of water vapor.
