Final answer:
In the reaction 2NaClO → 2NaCl + O₂, the coefficient of 2 in front of NaCl in the products indicates there are 2 NaCl compounds. The correct answer to the number of NaCl compounds on the product side is c. 2.
Step-by-step explanation:
The student asked how many NaCl compounds are on the product side of the chemical reaction 2NaClO → 2NaCl + O₂. To answer this, we must simply look at the coefficients in front of the chemical formulas in the balanced equation. Each coefficient indicates the number of molecules of that compound. Therefore, since the coefficient in front of NaCl on the product side is 2, this indicates that there are 2 NaCl compounds on the product side of the reaction.
The correct answer to the question is c. 2.
