Question

H2SO4+Mg(NO3)= Al+H3PO4= H3PO4+CaCl= MgSO3+K2S= SO2+O2= H2S+BaSO3=

Answer 1

H2SO4+Mg(NO3)2= 2HNO3+MgSO4

2Al+ 2H3PO4= 2AlPO4+ 3H2

3CaCl2 + 2H3PO4 = Ca3(PO4)2 + 6HCl

MgSO3+K2S= MgS+ K2SO3

2SO2+O2=2SO3

H2S+BaSO3= H2SO3+ BaS

Answer 2

It appears that you've provided a series of chemical reactions involving various chemical compounds. I'll provide you with the balanced chemical equations for each of these reactions:

1. H2SO4 + Mg(NO3)2 → MgSO4 + 2HNO3

2. Al + H3PO4 → AlPO4 + 3H2

3. H3PO4 + CaCl2 → Ca3(PO4)2 + 6HCl

4. MgSO3 + 2K2S → 2K2SO4 + MgS

5. 2SO2 + O2 → 2SO3

6. H2S + BaSO3 → BaS + H2SO3

Please note that these equations are balanced according to the law of conservation of mass, ensuring that the same number of atoms of each element appears on both sides of the equation. If you have any specific questions or need further information about these reactions, please feel free to ask!
