If a patient has a medical condition that causes his cells to absorb fewer than normal molecules, this patient would likely feel very tired.

Fewer absorption of Oxygen molecules would likely make the patient feel very tired.

The body requires oxygen for the processing of metabolic activities. Oxygen molecule helps in the breakdown of several carbohydrates and proteins and results in the formation of ATP. ATP is the form of energy that makes us active and helps in doing work.

The lesser absorption of oxygen by the human body will result in the lack of supply of oxygen to the cells. In this condition, the activity of the body slows down. The slowed activity will result in the person feeling tired.

Oxygen

Explanation:

Hemoglobin helps carry oxygen around the body. When your body doesn't have enough hemoglobin, less oxygen reaches your tissues and muscles, depriving them of energy. In addition, your heart has to work harder to move more oxygen-rich blood around your body, which can make you tired

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
