How many grams of sodium chloride, NaCl, can be formed from 25 g NaNO3?
The Correct Answer and Explanation is:
To determine how many grams of sodium chloride (NaCl) can be formed from 25 grams of sodium nitrate (NaNO3), we must use stoichiometry and the principle of conservation of mass. The key is to use a balanced chemical equation that shows how sodium nitrate reacts to form sodium chloride.
Step 1: Write the balanced chemical equation
We assume the reaction is a simple double displacement reaction, which can be represented as follows: NaNO3(aq)+NaCl(aq)→Na2O3(aq)+NaCl2(aq)\text{NaNO}_3 (aq) + \text{NaCl} (aq) \rightarrow \text{Na}_2 \text{O}_3 (aq) + \text{NaCl}_2 (aq)NaNO3(aq)+NaCl(aq)→Na2O3(aq)+NaCl2(aq)
