Answer:
<em>What quantity dictates the speed of a reaction?</em> The activation energy
Explanation:
According to the collision theory, when molecules collide, they must overcome an energy barrier for the reaction to take place. This energy, known as activation energy, is represented by the difference in energy between the initial state and the transition state. The higher the activation energy, the slower the reaction. That's why catalysts reduce the activation energy to accelerate the reaction.

The only nonmetal
that is liquid at room temperature is the element Br or Bromine. When we say at
room temperature, it means at zero degrees Celsius and at one atmospheric
pressure. The metal that is liquid at room temperature is the element Hg or
mercury.
Answer:
Because water can absorb a lot of heat without significant changes in temperature, it can prevent change in the temperature, and therefore pressure, of the compressed air.To maintain a constant temperature, we again pass the compressed air through the same chambers, this time letting it take up heat from the water
