California is ranked fourth in the nation in crude oil production. Crude oil is formed by small plants and animals
that died, fell to the bottom of the sea, and were covered by
mud that hardened. Use what you have just learned about
the effect of pressure on states of matter to explain how this
layer of hardened rock would eventually form oil.

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.
