Classify the following reactions as either synthesis or decomposition: 1) SO3 (g) + H2O (l) → H2SO4 (aq)

2) NH4NO3 (s) → N2O (g) + 2 H2O (g)

3) A + B → C

4) 2 H2O → 2 H2 + O2

5) 3 Fe (s) + O2 (g)→ Fe2O3 (s)

6) C → A + B

One of the hopes for solving the world's energy problem is to make use of the fusion reaction 21h +31h --> 42he + 10n + energy how much energy is released when 1 mol of deuterium is fused with 1 mol of tritium according to the above reaction? the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. the speed of light is 2.9979 x 108 m/s.
