CaCO₃(s) → CaO(s) + CO₂(g)

3O₂(g) → 2O₃(g)

2NH₃(g) → 3H₂(g) + N₂(g)

C₆H₆(l) → C₆H₆(g)

a molecule is broken into two or more smaller molecules

a reaction occurs that results in an increase in the number of moles of gas

a solid changes to a liquid

all of these

1 mole of KNO₃(l)

1 mole of KNO₃(s)

1 mole of H₂O(l)

1 mole of H₂O(g)

Molecular disorder increases

Molecules increase in number from solid to gas

Molecules are heavier in solid

Molecules are more reactive

It will not change. So... none of the above.

CaCO₃(s) → CaO(s) + CO₂(g)

3O₂(g) → 2O₃(g)

2NH₃(g) → 3H₂(g) + N₂(g)

C₆H₆(l) → C₆H₆(g)
