An ice cube that is 25.00 g (temp -20 C) is placed into 225.00 g of H2O that is 22 degrees C. What will the temperature be when the ice cube has just melted. Use 4.184 J/K*g for the specific heat capacity of ice and water. If the water is then heated to 80 degrees C by burning methane (delta H= =890.31 kJ/mol) how many grams of methane would you have to use?
