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.

Ahydrogen atom has 1 electron. how many bonds can hydrogen form? a) 1 b) 2 c) 3 d) 4 e) 5

8.98 dm3 of hydrogen gas is collected at 38.8 °c. find the volume the gas will occupy at -39.9 °c if the pressure remains constant.

Which theory was contradicted by experiments with the photoelectric effect? light spreads out after it passes through a small opening. as soon as light strikes metal, electrons will be ejected. visible light, regardless of color, will cause the ejection of electrons when striking metal. the kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.
