Question

Problem Solving: Show all work, units, sie fies and balanced equations needed to answer the following 1. To make the hydrogen necessary for the manufacture of ammonia in the Haber/Bosch process a steam reforming method is used. This method combines methane gas with steam (water gas) to make hydrogen gas and carbon monoxide gas. The AH for this reaction is + 206 kJ/mole. What amount of energy is needed to produce 1 kg of hydrogen? 2. Given: P.(s) + 3 O2(g) → P.O.(s) AH = -1640.1 KJ Pa(s) + 5 O2(g) → P.010(s) AH = -2940.1 KJ Use Hess Law to calculate the AH for P.O.(s) + 202(g) → PAO10(s) 3. Use appendix C to calculate the AHº for the thermite reaction where solid aluminum combines with solid ferric oxide to produce solid aluminum oxide and solid iron. Define AH°

Answer 1

a 1 kg hydrogen = 1000gm H2 molar mass of H2 = 2 g mol moles of Ha = 1000 = sooml У на cha + ,0 — co + 3H2 , pH = gos кә z 3 mol H2 need 206 kJ heat so sooml H2 will need soo x 206 = 34333-3 ka heat - is nee8e8 я /34 333-3 və he CScanned with CamScanner
