A 20.0-gram piece of metal at 88OC is cooled by a sample of water to 25OC. The amount of energy (energy given off by the metal is = energy absorbed by the water) is 320 Joules. Determine the specific heat of the unknown metal.

One of the hopes for solving the world's energy problem is to make use of the fusion reaction 21h +31h --> 42he + 10n + energy how much energy is released when 1 mol of deuterium is fused with 1 mol of tritium according to the above reaction? the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. the speed of light is 2.9979 x 108 m/s.

What does it mean for something to be dissolved in watera- it is submerged in water moleculesb-it is stirred in the water moleculesc- it is surrounded by water molecules d-it has water molecules added to it

Lord kelvin described the concept of absolute zero temperature and the laws relating to the change of thermal energy during chemical reactions what type of chemist would he be considered today
