On a shade-grown coffee plantation, smaller coffee plants grow in the shade of forest trees. the practice produces fewer coffee beans than growing coffee in full sun, but it is more sustainable because it provides habitat for forest birds. what is one drawback of growing coffee in the shade?

a. it reduces habitat for native species.

b. it costs more than other growing methods.

c. it increases the variety of crops on a farm.

d. it provides farmers with greater profits.

The correct answer is B.

A can not be true because it provides habitats for birds

C can not be true because that is not a drawback

D can not be true because that is also not a drawback

B. It costs more than other growing methods.

Explanation:

B.It costs more than other growing methods.  is the correct option because growing coffee in a shade requires a particular set up like plastic or tin shade whose cost will be more. Also although the it is sustainable for providing a shelter to the forests birds but special measures should be taken so that these coffee plants remain unaffected by the bird population. Hence, it will cost more than the conventional method of farming coffee.

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
