Question

Write a balanced chemical equation for each chemical reaction.

a. Solid magnesium reacts with aqueous copper(1) nitrate to form aqueous magnesium nitrate and solid copper.
b. Gaseous dinitrogen pentoxide decomposes to form nitrogen dioxide and oxygen gas.
c. Solid calcium reacts with aqueous nitric acid to form aqueous calcium nitrate and hydrogen gas.
d. Liquid methanol (CH3OH) reacts with oxygen gas to form gaseous carbon dioxide and gaseous water."

Answer 1

a) Mg(s) + Cu(NO3)2(aq) → Mg(NO3)2(aq) + Cu(s) b) N2O5(g) → 2NO2(g) + O2(g) c) Ca(s) + 2HNO3(aq) → Ca(NO3)2(aq) + H2(g) d) 2CH3OH(l) + 3O2(g) → 2CO2(g) + 4H2O(g)

Step-by-step explanation:

a) The balanced chemical equation for the reaction between solid magnesium and aqueous copper(1) nitrate is:
Mg(s) + Cu(NO3)2(aq) → Mg(NO3)2(aq) + Cu(s)

b) The balanced chemical equation for the decomposition of gaseous dinitrogen pentoxide is:
N2O5(g) → 2NO2(g) + O2(g)

c) The balanced chemical equation for the reaction between solid calcium and aqueous nitric acid is:
Ca(s) + 2HNO3(aq) → Ca(NO3)2(aq) + H2(g)

d) The balanced chemical equation for the reaction between liquid methanol and oxygen gas is:
2CH3OH(l) + 3O2(g) → 2CO2(g) + 4H2O(g)
