How many grams of KCl (74.55 g/mol) is produced from 106 g of Cl2?

222.91g of KCl

Explanation:

First, we need to write a balanced equation for the reaction. This is illustrated below

2K + Cl2 —> 2KCl

Molar Mass of KCl = 74.55 g/mol

Mass of KCl from the balanced equation = 2 x 74.55 = 149.1g

Molar Mass of Cl2 = 2 x 35.45 = 70.9g.

From the equation,

70.9g Cl2 produced 149.1g of KCl.

Therefore, 106 g of Cl2 will produce = (106 x 149.1)/70.9 = 222.91g of KCl

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
