Activation energy is the amount of energy required to__________.
asambeis [7]

Answer:

Activation energy is the amount of energy required to convert the reactants into the activated complex (option B)

Explanation:

The activation energy is the minimum needed energy to make a reaction occurs. When the reaction occurs, the molecules of reactants joins together in a determined position, so when they bond all the molecules reactants, they make the activated complex. That's why we say, that the energy needed to make the molecules of reactants form the activated complex is finally the <em>activation energy</em>.

When the activated complex is formed, there is a few moment with all the molecules from reactants bonding together. By the end, they are separated so the products are been formed.

Sulfur oxides Carbon monoxides Chlorofluorocarbons (CFCs)Nitrates are responsible for the hole in the ozone layer.
svp [43]
The best answer for the question above would be the chloroflourocarbons or the CFCs. These chloroflourocarbons or CFCs are the ones responsible for the depletion of the ozone - which leads to leaving a hole in its layer. These gases eat out the ozone layer and allows harmful UV rays of the sun to come in the Earth.

What mole ratio would you use to calculate how many mole of oxygen gas would be?
pav-90 [236]
The mole ratio one would need to calculate will be the ratio of grams of O2 are in one mole; that's the atomic mass of oxygen from the periodic table.

Oxygen has an atomic mass of 15.998 (most of the time, rounding to 16 is fine). But remember, oxygen always exists in nature as a diatomic molecule (two atoms covalently bonded together) as O2...so (32 grams O2/1 mole O2)
