What is the percent/% yield if 4 moles of hydrogen is reacted with 3 moles of oxygen and produces 3 moles of water?
H₂ + 1/2 O2 -> H2O
a. 25%
b. 75%

Option B,   %

Explanation:

The percentage yield can be defined as the recovery of fraction of reactant as product in any reaction.

Here in this question -

Number of moles of hydrogen reacting

Number of moles of hydrogen recovered as final product

Hence the percentage yield would be

Yield is %

Hence, option B is correct

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
