3 chemical properties of acid are...

1 metal + acid =salt + hydrogen..
2 metaloxide + acid = salt +water
3 metal carbonate+acid = salt +carbon dioxide+water...
Hope it help

Answer 2

Answer:

Chemical properties of acid:

- Acids react with metals to produce salt and hydrogen gas

H2SO4 + Zn ---------> ZnSO4 + H2

-Acids react with metal carbonates to produce salt, carbon dioxide and water.

Na2CO3+HCl-------> 2NaCl+ H2O+ CO2

-Acids react with bases to produce salt and water.

NaOH + HCl-------> NaCl+ H2O

2. NaHCO3 + H------> CO2+ H2O
