Sometimes, the hot water produced by a solar water heater is not warm enough to meet the needs of the occupants of a building. A traditional water heater inside the building supplies additional thermal energy to the solar-warmed water. How can this method still reduce the overall amount of natural gas or electricity a building uses?

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.

consider the reaction below.

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m
