Based on their formulas which of these compounds is not likely to be an ionic compound: kbr, so2, or alcl3? explain.

The volume of hydrogen gas produced is 4.24 L

Explanation:

To calculate the number of moles, we use the equation:

Given mass of aluminium = 3.12 g

Molar mass of aluminium = 26.98 g/mol

Putting values in above equation, we get:

For the given chemical reaction:

As, NaOH is present in excess. It is considered as an excess reagent.

Aluminium is the limiting reagent because it limits the formation of product.

By Stoichiometry of the reaction:

2 moles of aluminium produces 3 moles of hydrogen gas

So, 0.116 moles of aluminium will produce = of hydrogen gas

To calculate the volume of hydrogen gas produced, we use the ideal gas equation:

where,

P = pressure of the gas = 750 torr

V = Volume of the gas = ?

T = Temperature of the gas =

R = Gas constant =

n = number of moles of the gas = 0.174 mol

Putting values in above equation, we get:

Hence, the volume of hydrogen gas produced is 4.24 L
