Need help fast In each term equation below a blank line shows one term missing the terms may be an elemental symbol a coefficient or a subscript decide which term would balance the equation write the missing term in the second column the. Determine the reactants third column and products forth column of the reaction some reactions may have only one reactant or product and other reactions may have only one reactant or product and other reactions may have multiple reactants or products write your answers in the spaces in the table the first reaction involves sodium chloride not sodium carbon and iodine

have a great day because if you dont you and i will be sad

explanation:

because dgjpwojefopjwp

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.

intensive properties because they do not depend on the amount of matter in the sample.
