Answer:
<u>-16200J</u>
Explanation:
(257J/g)(62.9g)
eliminate the variables
u get 16165.3
go to 3 significant digits
u get 16200
and since it is freezing we are taking out energy so it would be
-16200J
This question is based on Dalton's Law of Partial Pressure which states that "the total pressure of a system of gas is equal to the sum of the pressure of each individual gas (partial pressure).
Now, Partial Pressure of a gas = (mole fraction) × (total pressure)
⇒ Partial Pressure of Hydrogen =

×
= 0.31 atm
Thus the Partial Pressure of Hydrogen in the container is
0.31 atm.
Don't use the brakes too hard when u stop. That can cause the biker to fall forward.
Give me a thanks if it helps!!
