The number of moles of aluminum chloride that could be produced is 0.704 moles

First, we will write a balanced chemical equation for the reaction

The balanced chemical equation for the reaction between aluminum and chlorine is

2Al + 3Cl₂ → 2AlCl₃

This means 2 moles of aluminum (Al) will react with 3 moles of chlorine (Cl₂) to produce 2 moles of aluminum chloride (AlCl₃)

Now, to determine the number of moles of aluminum chloride that could be produced,

We will determine the number of moles of aluminum present in 19.0 g of Al

Using the formula

$Number\ of \ moles = \frac{Mass}{Molar\ mass}$

Mass of aluminum = 19.0 g

Molar mass of aluminum = 26.98 g/mol

∴ Number of moles of aluminum present = $\frac{19.0}{26.98}$

Number of moles of aluminum present = 0.704 moles

Since,

2 moles of aluminum (Al) reacts to produce 2 moles of aluminum chloride (AlCl₃)

Then,

0.704 moles of aluminum (Al) will react to produce 0.704 moles of aluminum chloride (AlCl₃)

Hence, the number of moles of aluminum chloride that could be produced is 0.704 moles

0.70 moles

Explanation:

$2Al+3Cl_2\rightarrow 2AlCl_3$

As can be seen from the chemical equation, 2 moles of aluminium react with 3 moles of chlorine.

According to mole concept, 1 mole of every substance weighs equal to its molar mass.

Moles of Al = $\frac{\text{ given mass of Al}}{\text{ molar mass of Al}}= \frac{19g}{27g/mole}=0.70moles$

As aluminium is the limiting reagent as it limits the formation of product and chlorine is the excess reagent as it is left unreacted.

2 moles of aluminium reacts to produce 2 moles of aluminium chloride.

0.70 of aluminium reacts to form = $\frac{2}{2}\times 0.70=0.70moles$ of aluminium chloride.

Thus 0.70 moles of aluminium chloride will be formed.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
