Question

1. Determine whether a reaction will take place in the following and write a complete balanced equation: You must include phase labels. Use NR for no reaction.

Ca(OH)2 (aq) + Al(NO3)3 (aq)    ?

Cu(C2H3O2)2 (aq) +     Na2SO4 (aq) ?

H2SO4 (aq) + KOH (aq) ?

2. Write the total ionic and the net ionic equations for the following:

3 H2 (g) + 2 AuCl3 (aq) ? 6 HCl (aq) + 2 Au (s)

3. Given the following equations:

2 H2O2 (aq) ? 2 H2O (l) + O2 (g) and

C2H4 (g) + 3 O2 (g) ? 2 CO2 (g) + 2 H2O (l)

The first reaction is the decomposition of hydrogen peroxide into water and oxygen gas. The oxygen gas generated in the first reaction is used in the second (combustion) reaction.

If I have 7.6 g of H2O2, how many grams of CO2 can I produce from the set of reactions?

Explanation / Answer

I am solving the first question, all subparts as per Chegg guidelines

Q1)

a) 3Ca(OH)2(aq) + 2Al(NO3)3(aq) ----------------- 3Ca(NO3)2(aq) + 2Al(OH)3(s)

b) Cu(CH3COO)2(aq) + Na2SO4(aq) ----------- 2CH3COONa(aq) + CuSO4(s)

c) H2SO4(aq) + KOH(aq) ----------------- K2SO4(aq) + H2O(l)
