In the carbon-oxygen cycle, carbon dioxide is used for and oxygen is used for respiration, photosynthesis ozone, respiration photosynthesis, respiration evaporation, condensation

Achange in the number of neutrons in an atom will change an blank . when the number of protons changes in an atom, a new element will form.

For the reaction, 4 a(g) + 3 b(g) => 2 c(g), the following data were obtained at constant temperature. experiment initial[a],mol/l initial [b],mol/l initial rate,m/min 1 0.200 0.150 5.00 2 0.400 0.150 10.0 3 0.200 0.300 10.0 4 0.400 0.300 20.0 which of the following is the correct rate law for the reaction? 1. rate = k[a]2[b]2 2. rate = k[a][b] 3. rate = k[a]2[b] 4. rate = k[a][b]2
