How many moles of Al are necessary to form 23.6 g of AlBr₃ from this reaction: 2 Al(s) + 3 Br₂(l) → 2 AlBr₃(s) ?

Gnoma [55]

Answer:

0.088 mole of Al.

Explanation:

First, we shall determine the number of mole in 23.6 g of AlBr₃.

This is illustrated below:

Mass of AlBr₃ = 23.6 g

Molar Mass of AlBr₃ = 27 + 3(80) = 267 g/mol

Mole of AlBr₃ =.?

Mole = mass/Molar mass

Mole of AlBr₃ = 23.6 / 267

Mole of AlBr₃ = 0.088 mol

Next, we shall writing the balanced equation for the reaction.

This is given below:

2Al(s) + 3Br₂(l) → 2AlBr₃(s)

From the balanced equation above,

2 moles of Al reacted with 3 mole of Br₂ to 2 moles AlBr₃.

Finally, we shall determine the number of mole of Al needed for the reaction as follow:

From the balanced equation above,

2 moles of Al reacted to 2 moles AlBr₃.

Therefore, 0.088 mole of Al will also react to produce 0.088 mole of AlBr₃.

a. A solution of potassium dichromate is reduced to chromium(III) ions by zinc metal in the presence of an acid causing the solu

asambeis [7]

Explanation:

It is known that molecular formula of potassium dichromate is $K_{2}Cr_{2}O_{7}$ . As potassium has an oxidation state of +1 and an oxygen atom has an oxidation state of -2.

Let the oxidation state of chromium is x. Therefore, calculate the oxidation state of chromium as follows.

$K_{2}Cr_{2}O_{7}$ = 0 (as the molecule is neutral)

$(2 \times 1) + 2x + (-2 \times 7)$ = 0

2 + 2x - 14 = 0

x = +6

Thus, we can conclude that the oxidation state of the chromium in the potassium dichromate molecule is +6.
