A student made a model of a river using a tray filled with sand. The student poured a cup of water into the top of the tray. The student then poured a bucket of water into the top of the tray. What evidence would most likely be observed?

Group of answer choices

The bucket of water would cause more erosion than the cup of water.

The cup of water would cause more erosion than the bucket of water.

The cup of water and the bucket of water would not cause any erosion.

The cup of water and the bucket of water would cause the same erosion.

they are all solids.

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
