please help me with these chemistry equations?

Question

i have tried everything but do not know the answers. i would really appreciate help.

Identify which type of reaction each of the following represents: (2 points each)

2H2SO4 + 4 KOH ---> 2 K2SO4 + 4H2O ________________________

Zn(s) + 2HCl(aq) --> ZnCl2(aq) + H2(g) _____________________

2Li(s) + Br2(l) --> 2 LiBr(s) ______________________________

2H2O(l) --> 2H2(g) + O2(g) _______________________

Finish the following reactions and balance the equations. (4 points. each)
(Use the Helps and Hints file for help completing the reactions. Go through it step by step and let your instructor know if you have any questions.)

NaOH(aq) + Fe(NO3)3(aq) -->

NH3 -->

H2 + O2 -->

Mg + H2SO4 -->

thanks a lot.

Answer 1

Neutralization
Replacement
Combination
Decomposition

3NaOH + Fe(NO3)3 ===> 3NaNO3 + Fe(OH)3
2NH3 ===> N2 + 3H2
2H2 +O2 ===> 2H2O
Mg + H2SO4 ===> MgSO4 + H2
