Give the three rules for thermochemistry Consider the thermochemical equation for the combustion of methane: CH_4(g) + 2O_2(g) rightarrow CO_2(g) + 2H_2O(g) Delta H = -890 kJ/mol How much heat is released when 4.50g of methane (CH_4) is burned at constant pressure? What are the units of specific heat? If you know the specific heat of copper, what additional information do you need to calculate the heat capacity of a particular piece of copper pipe? Stainless steel accessories in cars are usually plated with chromium to give them a shiny surface and to prevent rusting. When 5.00g of chromium at 23.00 degree C absorbs 62.3 J of heat, the temperature increases to 50.8 degree C. What is the specific heat of chromium?
