Answer:
a. Ca(s) + N₂(g) + 3O₂(g) → Ca(NO₃)₂(s).
b. C(s,graphite) + 2H₂(g) + 1/2O₂(g) → CH₃OH(l).
c. 3NaCl(s) + 4O₃(g) → 3NaClO₄(s).
Explanation:
<em>a. The formation reaction of Ca(NO₃)₂(s) is:</em>
Ca(s) + N₂(g) + 3O₂(g) → Ca(NO₃)₂(s).
- 1.0 mole of solid Ca reacts with 1.0 mole of N₂ gas and 3.0 moles of O₂ gas to produce 1.0 mole of solid Ca(NO₃)₂.
<em>b. The formation reaction of CH₃OH(l) is:</em>
C(s,graphite) + 2H₂(g) + 1/2O₂(g) → CH₃OH(l).
- 1.0 mole of solid C (graphite) reacts with 2.0 mole of H₂ gas and 0.5 mole of O₂ gas to produce 1.0 mole of liquid CH₃OH.
<em>c. The formation reaction of NaClO₄(s) is:</em>
3NaCl(s) + 4O₃(g) → 3NaClO₄(s).
- 3.0 moles of solid NaCl react with 4.0 moles of O₂ gas to produce 3.0 moles of solid NaClO₄.
