A 32.5 g sample of tin is heated to 132˚C and placed in a calorimeter containing 125 g of water at 25.0 ˚C. After the metal cools, the final temperature of the metal and water is 27.0˚C. Calculate the specific heat capacity of tin

Compare and contrast the bohr model and the electron cloud models of the atom.

Select all of the statements which are true. electrons are located in shells or orbits around the atom. electrons orbit slowly around the atom. electrons travel in one flat path around the nucleus of an atom. the valence of an atom is determined by the number of electrons in the atom's outermost shell.

Liquid ammonia is produced at high temperatures and under great pressure in a tank by passing a mixture of nitrogen gas and hydrogen gas over an iron catalyst. the reaction is represented by the following equation. n2(g) + 3h2(g) → 2nh3(g) changing all but one experimental condition will affect the amount of ammonia produced. that condition is a) increasing the concentration of both reactants b) changing the temperature within the tank c) decreasing the pressure within the tank. d) increasing only the amount of nitrogen present.
