One of the categories that mostly includes worthwhile tasks is chemistry subject. However, a lot of teachers and students find it challenging to teach and learn about chemistry. The socio-economic development of many businesses, notably the pharmaceutical and petrochemical industries, depends heavily on it, but it is also quite demanding. However, your assignments will be simple if you use My Homework Writers. The following is an illustration of a query.
Calculate ΔHo for the following reaction ussing the given bond dissociation energies CH4(g) + 2O2(g) –> CO2(g) + 2H2O(g) BOND ΔHo (kJ/mol) O-O 142 H-O 459 C-H 411 C=O 799 O=O 498 C-O 358 ΔHo = ? kJ/mol Is the reaction endothermic or exothermic?
