Please can anyone help with these?

'Using the examples hydrochloric acid (HCl) and Sodium (Na), write the word and balanced symbol equations for the reaction of an acid with a metal".

"Using the examples HCl and ZnO (Zinc Oxide), write the word and balanced symbol equations for the reaction of an acid with a metal oxide"

Same sorta thing for Nitric Acid and Potassium Hydroxide - write both symbols for the reaction of an acid with a metal hydroxide.

Last one -

Nitric Acid (HNO3) and Zinc Carbonate (ZnCO3) write both equations for the reaction of an acid with a metal carbonate.

Many thanks in advance if anyone can help me out with this.

General equation for reaction of an acid and a metal

acid + metal = salt + hydrogen

So for your example the word equation is :
hydrochloric acid + sodium = sodium chloride + hydrogen

the balanced symbol equation is:
2HCL + 2Na = 2NaCl + H2

General equation for acid + metal oxide

acid + metal oxide = salt + water

For your example the word equation is :

hydrochloric acid + zinc oxide = zinc chloride + water

symbol equation is: 2HCL + ZnO = ZnCl2 + H2O

General equation for acid + metal carbonate is:

acid + metal carbonate = salt + carbon dioxide + water

for your example:
word equation is :

nitric acid + zinc carbonate = zinc nitrate + carbon dioxide + water

symbol equation:

2HNO3 + ZnCO3 = Zn(NO3)2 + CO2 + H2O
