Read the following chemical equations. Reaction 1: H2S + Cl2 → 2HCl + S
Reaction 2: Fe + S → FeS

Which of the following statements is true for both the chemical equations? (5 points)

Chlorine is reduced in reaction 1 and iron is reduced in reaction 2.

Chlorine is oxidized in reaction 1 and iron is oxidized in reaction 2.

Chlorine is oxidized in reaction 1 and iron is reduced in reaction 2.

Chlorine is reduced in reaction 1 and iron is oxidized in reaction 2.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8

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
