Answer 2

ok so answer would be C Mg(NO3)2 cause it is a salt from strong base and strong acid so reaction with strong acid wouldnt yeild much towards creating of MgSO4 cause sulfuric acid is also strong acid so it cant push out strong conjugated base NO3-
where CO3 2- is a weak acid and strong acid namely H2SO4 can push it out

Answer 3

H2SO4 + Mg(NO3)2--->MgSO4+HNO3--->so like will it affect the pH?
