How is Earth's electromagnetic field generated and what role does it play for all living organisms? What would happen if it doesn't exist? Explain.

Explanation:

Earth's magnetic field is generated by interactions in its molten outer core. As the flowing iron generates electric currents, the electromagnetic field is constantly changing.

The electromagnetic  fields surround the entire planet and act as protective shields blocking out the harmful effects of solar radiation, cosmic rays, sand, and other forms of space weather.

If it did not exist then :-

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
