C. The ability to reproduce by dividing.

Explanation:

Not all living things reproduce by dividing. For example mammals don't do that. But, cells reproduce by dividing.

b. the ability to maintain homeostasis.

Explanation:

Homeostasis is the ability of the body to regulate its temperature within a given range of values. This is majorly a property of living thigns with a constant body temperature, e.g human being. Not all living thigns have this characteristics, like if you compare man and plants.

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
