What do geologists call the underground molten mixture of rock-forming substances, gases, and water that is found in the mantle?

A. lava
B. magma
C. batholith
D. slurry

B.) Magma

Explanation:

Lava - Magma that reaches Earth's through a volcanic vent

Magma - Composed of molten mixture of rock-forming substances, gases and water

Batholith - Very large igneous intrusion extending deep in the earth's crust

Slurry - Semiliquid mixture, typically of fine particles of manure, cement, or coal suspended in water

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

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
