When 2 moles of CO(g) read with 0:(g) to form CO2(g) according to the following

Question

When 2 moles of CO(g) read with 0:(g) to form CO2(g) according to the following equation. 566 kJ ol energy are evolved. 2CO(g) + O2(g) rightarrow 2CO2(g) Is this read ion endothermic or exothermic? What is the value of q? kJ When 1 mole of CH4(g) reacts with O2(g) to form CO2(g) and H2O(g) according to the following equation. 802 KJ of energy are evolved. CH4(g) + 2O2(g) rightarrow CO2(g) + 2H2O(g) Is this reaction endothermic or exothermic? What is the value of q? kJ How much energy is required to raise the temperature of 12.1 grams of solid gold from 20.0 degree C to 38.5 degree C ? Answer: Joules. A sample of solid diamond is heated with an electrical coil If 90.3 Joules of energy are added to a 11.3 grain sample initially at 23.7 degree C. what is the final temperature of the diamond?
