Hi I am having trouble answering this question. Thank you.
Here is some information you have at your disposal:C2H2(g) + 5/2O2(g) → 2CO2(g) + H2O(l) ΔH = −1300. kJ (4 s. f.) C(s) + O2(g) → CO2(g) ΔH = −394 kJ H2(g) + ½O2(g) → H2O(l) ΔH = −286 kJ Apply Hess’ law and obtain the enthalpy change for the following reaction. Show all your work. 2C(s) + H2(g) → C2H2(g)
Is my calculations correct?. Yellow is observations which are known. White is my calculations.
please help with drawing and explaining final products from theese reactions, and which one has a major and minor product??
