4.All metal oxides react with water to
give salt and acid.​

Answer 1

Answer:

option 4th

Explanation:

• Metal oxide + acid→A salt + water
• Metal oxide + acid→A salt + waterMgCO3+H2SO4→MgSO4+H2O+CO2

• Metal oxide + acid→A salt + waterMgCO3+H2SO4→MgSO4+H2O+CO2 Metal oxide + water→Base
• Metal oxide + acid→A salt + waterMgCO3+H2SO4→MgSO4+H2O+CO2 Metal oxide + water→BaseMgO+H2O→Mg(OH)2

Metal oxide + acid→A salt + waterMgCO3+H2SO4→MgSO4+H2O+CO2 Metal oxide + water→BaseMgO+H2O→Mg(OH)2Option 4th is the incorrect statement

i hope this help u pls mark me as brainliest......
