 please help with these chemistry problems! and show work i need to learn how... ...to work them.? 1.Consider the reaction, 2 C4H10(g) + 13 O2(g) => 8 CO2(g) + 10 H2O(l), for which ?H = -5760 kJ. If 4,849 kJ of heat is produced, how many grams of H2O will also result? 2. When 1 mol of CS2(l) forms from its elements at 1 atm and 25°C, 89.7 kJ is absorbed, and it takes 27.7 kJ to vaporize 1 mol of the liquid. How much heat is absorbed when 1 mol of CS2(g) forms from its elements at these conditions?  |
