✔ 最佳答案

The equations are :

Sulphuric acid+Potassium carbonate=??
H2SO4 + K2CO3 → K2SO4 + H2O + CO2

Sulphuric acid+Aluminium oxide=??
3H2SO4 + Al2O3 → Al2(SO4)3 + 3H2O

Sulphuric acid+Sodium carbonate=??
H2SO4 + Na2CO3 → Na2SO4 + H2O + CO2

Sulphuric acid+Calium oxide=??
H2SO4 + CaO → CaSO4 + H2O

A formula is used to represent a chemical, e.g. the formula of sodium chloride is NaCl.An equation is used to represent a reaction, e.g. C O2 → CO2 represents the reaction of carbon of oxygen giving carbon dioxide.I think you are asking equations (not formulas) in your question.
