Answer:
The correct answer is They provide the molar ratio of reactant and products in a chemical reaction.
Explanation:
Balanced chemical equation helps us to calculate the number of moles of both reactant and product.For example
2H2+O2=2H2O
From the above balanced equation it can be stated that 2 molecules of hydrogen(H2) reacts with 1 molecule of oxygen(O2) to form 2 molecules of water.
Answer:
The answer is all three
Explanation:
Balanced chemical equations demonstrate that the total number of atoms of each element are conserved during a chemical reaction. These equations are useful because they provide the molar ratios of the reactants and products in a chemical reaction, and they allow the theoretical masses of reactants and products to be calculated.
