Consider the following reaction. CH4 + 2O2 -> 2H2O + CO2 ΔH = -890 kJ/mol If 45 g of methane combust, then what amount of energy is released?
113 kJ of heat is absorbed when one mole of carbon reacts with one mole of water. Energy + C + H2O → CO + H2 According to the reaction above it can be concluded that the reaction is a endothermic, because the change of enthalpy was negative b exothermic, because the change of enthalpy was negative c exothermic, because the change of enthalpy was positive d endothermic, because the change of enthalpy was positive

A 5.43 g sample of an unknown salt (MM = 116.82 g/mol) is dissolved in 150.00 g water in a coffee cup calorimeter. Before placing the sample in the water, the temperature of the salt and water is 23.72°C. After the salt has completely dissolved, the temperature of the solution is 28.54°C. If -3.13 x 10 J of heat was lost during the dissolution reaction of 0.0465 moles of the unknown salt, what is the enthalpy change (in kJ/mol of salt) for the dissolution reaction? Type here to search
