307g of an unknown mineral is heated to 98.7 C and placed into a calorimeter that contains 72.4 g of water at 23.6C. the heat capacity of the empty calorimeter was 15.7 J/K. the final temperature of the calorimeter is 32.4C. What is the specific h..
Suppose 12.0 g of carbon (C) reacts with 65.0g of sulfur (S) to give 76.0 g of the compound carbon disulfide (CS2). In the process, all the carbon gets used up, but some elemental sulfur is left over. For the law of conservation of matter to b..
