Answer:
A
Explanation:
Ball bounces because of the difference in the air pressure on the outside of the ball, and opposite the point of impact, and the pressure inside of the ball. This means that the inside of the ball now has less space to contain the air molecules contained inside the ball, increasing the pressure inside the ball.
Answer:
2.23 x 10^-4 mol
Explanation:
0°C =273 K
PV= nRT
n= PV/RT
n= (5.00 atm * 0.0010 L)/ (0.0821 * 273 K)
n= 2.23 x 10^-4
It should be Carbon dioxide, hope that helps!
