Answer:
When chlorine and bromine atoms come into contact with ozone in the stratosphere, they destroy ozone molecules.
Explanation:
Gravity, running water (rivers, etc.), wind, waves,and glaciers.
Answer: 64.71 L. The balloon will have expanded.
Explanation: 1st, sea level is equal to 1 atm. You will then use Boyle’s Law: P1V1=P2V2.
P1= 1 atm
V1= 55 L
P2= 0.85 atm
V2= ?
Now insert the numbers for the letters:
(1)(55)=(0.85)(V2)
55=0.85V2
Divide by 0.85 on both sides:
V2=64.71L
Now, according to Boyle’s Law, when pressure decreases, volume increases. That’s why the balloon inflates rather than deflates.
The appropriate answer is they decrease the potential energy difference between reactant and product. They do this by bringing products and reactants together at the active site on the enzyme molecule. Enzymes are biological catalysts. They increase the rate of a chemical reaction without being used up in the reaction itself. So one molecule of an enzyme is used many times to catalyze the reaction of other molecules.
