Question

An unbalanced chemical equation is shown:

2CaO + 2H2O → Ca(OH)2

Which of the following statements explains why the equation is not balanced?

Four molecules of Ca(OH)2 should be produced during the decomposition reaction.
Two molecules of Ca(OH)2 should be produced during the decomposition reaction.
Four molecules of Ca(OH)2 should be produced during the synthesis reaction.
Two molecules of Ca(OH)2 should be produced during the synthesis reaction.

Answer 1

Answer:

1. 2CaO + 2H2O → Ca(OH)2

.2CaO + 2H2O → Ca(OH)2

Four molecules of Ca(OH)2 should be produced during the decomposition reaction.

Two molecules of Ca(OH)2 should be produced during the decomposition reaction.

Four molecules of Ca(OH)2 should be produced during the synthesis reaction.

Two molecules of Ca(OH)2 should be produced during the synthesis

Answer 2

Answer:

Three molecules of N2 should be produced during the decomposition.
