Inorganic Chemistry equations:period 3

Question 1

Period 3 + H2O:

Answer 1

2Na (s) + 2H2O (l) → 2 NaOH (aq) + H2 (g)
Mg (s) + 2H2O (l) → Mg(OH)2 (aq) + H2 (g)
Mg (s) + H2O (l) → MgO (s) + H2 (g)

Question 2

Period 3 + O2:

Answer 2

2 Na (s) + ½ O2 (g) → Na2O (s)
Mg (s) + ½ O2 (g) → MgO (s)
2Al (s) + 1½O2 (g) → Al2O3 (s)
Si (s) + O2 (g) → SiO2 (s)
P4 (s) + 5O2 (g) → P4O10 (s)
S (s) + O2 (g) → SO2 (g)

Question 3

Period 3 oxides + H2O:

Answer 3

Na2O (s) + H2O (l) → 2NaOH (aq)
MgO (s) + H2O (l) → Mg(OH)2 (aq)
P4O10 (s) + 6H2O (l) → 4H3PO4 (aq)
SO2 (g) + H2O (l) → H2SO3 (aq)
SO3 (g) + H2O (l) → H2SO4 (aq)

Question 4

Basic Period 3 oxides & acids:

Answer 4

Na2O (s) + 2HCl (aq) →2 NaCl (aq) + H2O (l)
MgO (s) + H2SO4 (aq) → MgSO4 (aq) + H2O (l)

Question 5

Amphoteric period 3 oxide:

Answer 5

Al2O3(s) + 3H2SO4 (aq) → Al2(SO4)3 (aq) + 3H2O (l)
Al2O3 (s) + 2NaOH (aq) + 3H2O (l) → 2 NaAl(OH)4 (aq)

Question 6

Acidic oxides + bases examples:

Answer 6

SiO2 (s) + 2NaOH (aq) → Na2SiO3 (aq) + H2O (l)
P4O10 (s) + 12NaOH (aq) → 4Na3PO4 (aq) + 6H2O (l)
SO2 (g) + 2NaOH (aq) → Na2SO3 (aq) + H2O (l)
SO3 (g) + 2NaOH (aq) → Na2SO4 (aq) + H2O (l)
