ur lab partner has made the observation that we always measure the mass of chemicals in lab, but then use mole ratios to balance equations. What if your lab partner decided to balance equations by using masses as coefficients? Is this possible? Why or why not?

Interpretation Introduction

Interpretation:

The validation corresponding to the fact that whether it is possible to balance the chemical equations by using the masses as coefficients or not is to be stated. The reason corresponding to the correct result is to be stated.

Concept Introduction:

Stoichiometry helps in determining the relationship between the number of moles of the reactants and products that are involved in a reaction. For proper calculations the reaction must be balanced.

A single balanced chemical equation reflects the overall stoichiometry of the reaction.

Explanation of Solution

Moles of reactant are responsible for determining the limiting reactant among the given reactants. The example of a balanced equation is, if 2moles of NaOH reacts with 1mole of H2SO4, it forms 1mole of Na2SO4 as shown below.

2NaOH+H2SO4Na2SO4+2H2O

In the above reaction,
