Question:

Consider the reaction between sodium metal and chlorine gas to form sodium chloride (table salt):

{eq}\displaystyle 2Na(s) + Cl_2(g) \longrightarrow 2NaCl(s). {/eq}

If {eq}12.5 \ g {/eq} of sodium react with sufficient chlorine, how many grams of sodium chloride will be formed?

A. {eq}15.9 \ g {/eq}

B. {eq}31.8 \ g {/eq}

C. {eq}63.6\ g {/eq}

D. {eq}4.92 \ g {/eq}

E. {eq}9.84 \ g {/eq}

Balanced Chemical Equations:

The balanced chemical equation represents the substances as a chemical reaction progresses. The representation of the substances are in terms of the chemical formula with the corresponding coefficients. The coefficients would be the parameter that helps us maintain the mass conservation in the expression.
