Calculate the total heat flow, qtotal, when 15.0 g of water is cooled from 115°C to -20.0°C. The heat of fusion of water is 335 J/g, and the heat of vaporization of water is 2.26 kJ/g. The specific heat of liquid water is 4.183 J/gºC, the specific heat of steam is 2.0 J/g°C, and the specific heat of ice is 2.1 J/g°C.

Turbo the snail moves across the ground at a pace of 12 feet per day. if the garden is 48 feet away, how many days will it take for the snail to get there?

What will most likely happen when two bromine atoms bond together?

Americium-241 undergoes fission to produce three neutrons per fission event. if a neutron-absorbing material is mixed in with this sample so that the rate of neutron production drops down to 1.8 neutrons per fission event, which will be effective at achieving a critical mass? check all that apply. remove a deflective shield surrounding the sample. remove absorbent material mixed in with the sample. compress the sample of americium-241.
