Answer:
d. Heat is released from the reaction
Explanation:
A negative enthalpy change indicates that it is an exothermic reaction. Exothermic reactions release heat.

Joaquin spent $15 on his jeans :) hope this was right!
At the right angle. Both molecules have to be going fast enough and at the right angle or else they will just bounce off
Answer:
The new pressure is 456.76 mmHg
Explanation:
Step 1: Data given
The initial volume of the gas = 5.80 L
The initial pressure of the gas = 1.00 atm
The volume of the gas increases to 9.65 L
The temperature is kept constant
Step 2: Calculate the new pressure
P1*V1 = P2¨V2
⇒with P1 = the initial pressure of the gas = 1.00 atm
⇒with V1 = the initial volume of the gas = 5.80 L
⇒with P2 = the new pressure = TO BE DETERMINED
⇒with V2 = the increased volume of the gas = 9.65 L
1.00 atm * 5.80 L = P2 * 9.65 L
P2 = (5.80 / 9.65)
P2 = 0.6010 atm
Step 3: Convert pressure from atm to mm Hg
0.6010 atm * 760 mmHg = 456.76 mmHg
The new pressure is 456.76 mmHg
