What is the mass of water which can dissolve 8.6 g of lithium chloride in a 6.70% by mass solution

~120 grams water

Explanation:

% LiCl = (Mass LiCl) / (Mass of Soln) x 100%

= Mass LiCl / (Mass H₂O + Mass LiCl) x 100% = 6.7% (divide both sides by 100%)

=> Mass LiCl / Mass H₂O + Mass LiCl = 0.067

=> Mass LiCl = 0.067(Mass H₂O) + 0.067(Mass LiCl)

Solve for Mass H₂O:

=> Mass LiCl - 0.067(Mass LiCl) = 0.067(Mass H₂O)

=> Mass H₂O = (Mass LiCl - 0.067(Mass LiCl) / 0.067

= 8.6g - 0.067(8.6g) / 0.067 = 8.0238g / 0.067 = 119.76g H₂O = ~120grams

120 grams

Explanation:

Hope this helps:)

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.

a electronegativity decreases beacuse the size of nucleus is bigger.
