What would happen to the climate and weather conditions if the Earth did not have ocean currents? 1. The equator would be incredibly hot all the time, and the poles would be incredibly cold creating climate conditions that would be nearly impossible to live in.
2.Evaporation and condensation from ocean surface waters would stop resulting in the lack of rainfall.
3.
The climate would become incredibly hot contributing to current climate change.
4.The equator would be incredibly cold all the time, and the poles would be incredibly hot creating climate conditions that would be nearly impossible to live in.

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.
