Solution: Use the following equations to answer the next four questions:i. H2O(s) ⟶ H2O(l)ii. Na+(aq) + Cl−(aq) + Ag+(aq) + NO3−(aq) ⟶ AgCl(s) + Na+(aq) + NO3−(aq)iii. CH3OH(g) + O2(g) ⟶ CO2(g) + H2O(g)iv. 2H2O

Problem

Use the following equations to answer the next four questions:

i. H2O(s) ⟶ H2O(l)

ii. Na+(aq) + Cl(aq) + Ag+(aq) + NO3−(aq) ⟶ AgCl(s) + Na+(aq) + NO3−(aq)

iii. CH3OH(g) + O2(g) ⟶ CO2(g) + H2O(g)

iv. 2H2O(l) ⟶ 2H2(g) + O2(g)

v. H+(aq) + OH(aq) ⟶ H2O(l)

(a) Which equation describes a physical change?
