I need more help with chemistry please

Question

1. Ammonium sulfate is mixed with potassium hydroxide

2. ammonium sulfide is reacted with hydrochloric acid

3.solid calcium carbonate is reacted with sulfuric acid

4.potassium sulfite is reacted with hydrobromic acid

5. potassium sulfide is reacted with niric acid

6. ammonium iodide magnesium sulfate

Answer 1

NH4SO4   +  KOH --> NH4OH   +  K2SO4

(NH4)2S   +  HCl --->   NH4Cl     + H2S

CaCO3   +   H2SO4    ---> CaSO4    +  H2CO3

K2SO3    +   HBr   --->    KBr   +   H2SO3

KS2    +    HNO3    --->  KNO3    +   KH

NH4I   +   MgSO4 --->   MgI2    +    (NH4)2SO4

You need to balance them tho

hope tht helps :)
