Alex and Marissa were observing a dog digging a hole in the ground. They tried to draw conclusions about which of Earth's five spheres were interacting. Alex argued that since the dog was digging in the ground, only two spheres were interacting.

Marissa argued that three spheres were interacting in this situation.

Determine who you agree with and explain why. Be sure to list the spheres and explain how they are interacting in the scenario.

frequency, z, and the collision density, z, in carbon dioxide (co2), r 180 pm at 30 °c and 120 kpa

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
