A scientist built a computational model to investigate what happens when magma comes into contact with the ground surface. In the model, the ground surface was 293K, whereas the magma was 1,500K. The model examined different depths of the magma away from Earth's surface and toward the core. Over a greater amount of time, more magma cooled. What form of heat transfer accounts for the magma cooling?

Conductive heat transfer is most likely responsible for the cooling of the magma

Explanation:

The Earth's core is continuously cooling due to human's digging, allowing for more space and heat escape from the Earth's core. All magma closer to the core would have its heat absorbed by the core, hereby increasing its coolness.

This heat transfer process is common to conduction.

I hope this was helpful.

i'm not sure

explanation:

i'll try whatever you got

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
