Determine the chemical amount of chlorine required to produce 2.50 mol of lithium chloride, LiCl, according to the equation Select one: a. 1.50 mol b. 2.00 mol c. 1.25 mol d. 1.75 mol

c. 1.25 mol

Explanation:

You might find it helpful to sort the information under the equation like a chart. "n" is the symbol for moles.

        2 LiI(aq) + Cl₂(aq) → 2 LiCl(aq) + I₂(s)

n                           ?           2.50 mol

We are looking for the chemical amount of chlorine, or moles of chlorine.

To find the number of moles, you need the mole ratio.

The mole ratio is the same as the coefficients in the equation.

   Cl₂ to LiCl

1 mol to 2 mol

Start with the given moles (2.50 mol for LiCl) and multiply by the mole ratio.

Since we are looking for molCl₂, write molCl₂ on top.

           Units for molLiCl cancel out

         <= notice that we keep 3 significant figures

The chemical amount of chlorine is 1.25 mol.

it would be d. henry moseley

hope this !

and sorry if i'm late. have a good rest of your day! : d

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.
