Question #c695a

Answer 1

See below.

Explanation:

a) `"1Fe" + "1CuSO"_4 →"1Cu" +"1FeSO"_4`

This is a single replacement reaction, because an `"Fe"` atom replaces a `"Cu"` atom in `"CuSO"_4`.

b) `"Ni"("NO"_3)_2 + "NaCl" →` No Reaction.

There is no reaction because all the substances are soluble in water.

c) `"2Mg + 1O"_2 → "2MgO"`

This is a combustion reaction because the magnesium is combining with the oxygen to form the oxide,
