A metal sample weighing 123.00 grams and at a temperature of 95.9 degrees Celsius was placed in 40.50 grams of water in a calorimeter at 24.1 degrees Celsius. At equilibrium the temperature of the water and metal was 42.9 degrees Celsius. What is the change in temperature of the water? (Report this as a positive value)

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.

< > according to newton's third law of motion, forces always act in equal but opposite pairs. another way of saying this is for every action, there is an equal but opposite reaction.< >
