In Journey to the Center of the Earth, by Jules Verne, an adventurer travels through the layers of Earth until he reaches the center. While it is not possible actually to travel through all of the layers of Earth, in what order would the adventurer have traveled to reach the center? Rearrange the layers into the correct order. Place the outer layer at the top and the innermost layer at the bottom.

window cleaner is ammonia dissolved in water. this is an example of a

answer: - first one is the correct answer. .

explanations: - potassium sulfide is and cobalt(ii) chloride is .

charge on k is +1, charge on s is -2, charge on co is +2 and charge on cl is -1.

in a double replacement reaction the ion exchange takes place. in general the reaction looks like:

if one of the product is insoluble as per solubility rules then a precipitate of it is formed.

when we mix the aqueous solutions of potassium sulfide and cobalt(ii) chloride then chloride ion goes with potassium ion and sulfide ion goes with cobalt ion and the balanced equation is written as:

k and cl has equal charges, similarly co and s has equal charges and hence no subscripts are used for the product side.

as per the solubility rules, cos is insoluble and so it's precipitate is formed.

looking at the given choices, first choice is correct.

it's
