Can someone may sure that I balanced the following groups of equations correctly.

Question

Write an equation to show how acetic acid reacts with water to produce ions in solution.
C2H4O2 + H2O >>>>>>> H3O + C2H3O

Write an equation for the neutralization of HCl and NaOH.
HCl + NaOH >>>>>> NaCl + H2O

Write the equation representing the decomposition of CaCO3.
CaCO3 >>>>>>> Ca+ CO

Complete and balance the following equations and name the product formed.
I am sure that I have them balanced correctly. Could you let me know if I have the correct product?

K2O(s)+H2O(l) >>2KOH = potassium hydroxide.

SrO(s) +H2O(l) >> Sr(OH)2 = strontium hydroxide.

SO3(s) + H2O(l) >>H2SO4 = sulfuric acid.

N2O5(s) + H20(l) >>>2HNO3 = hydrogen nitrate.

Answer 1

Write an equation to show how acetic acid reacts with water to produce ions in solution.
C2H4O2 + H2O >>>>>>> H3O + C2H3O
You need to show the charges on the ions; i.e., H3O^+ + C2H3O^-

Write an equation for the neutralization of HCl and NaOH.
HCl + NaOH >>>>>> NaCl + H2O
OK

Write the equation representing the decomposition of CaCO3.
CaCO3 >>>>>>> Ca+ CO
CaCO3 ==> CaO + CO2

Complete and balance the following equations and name the product formed.

K2O(s)+H2O(l) >>2KOH = potassium hydroxide.
OK

SrO(s) +H2O(l) >> Sr(OH)2 = strontium hydroxide.
OK

SO3(s) + H2O(l) >>H2SO4 = sulfuric acid.
OK

N2O5(s) + H20(l) >>>2HNO3 = hydrogen nitrate.
The common name is nitric acid
