I believe the answer is A.
Percentage yield=(actual yield/theoretical yield) x 100%
= (45/50) x 100%
= 90%
<span>There are three isotopes of hydrogen H-1, H-2, and H-3 all of these isotopes have "One Proton"
Hope this helps!</span>
Explanation:
As we know that molecules of a gas move far away from each other because they are held by weak Vander waal forces. So, when a balloon is filled by a gas then molecules of a gas strike at its walls leading to more number of collisions.
This will also lead to more expansion of the balloon. As we know that pressure is the force exerted n per unit area of a substance or object.
Thus, more is the kinetic energy of the molecules of the gas more will be the force exerted by them. Hence, more will be the pressure exerted.
The answer would be <span>0.1 hope i helped you out :)</span>
