Explanation:
Explanation:
The compound form in this type of combination is an ionic or electrovalent substance.
Some of the properties of xy, an electrovalent compound are;
- they are usually hard solids with a high melting point or liquids with high boiling points.
- they are soluble in water and insoluble in non-polar solvents.
- in molten form or aqueous form, they conduct electric current.
- in aqueous form, their reactions are usually fast.
The balanced equation for the above reaction is
2Al + 6H₂O ---> 2Al(OH)₃ + 3H₂
stoichiometry of Al to H₂ is 2:3
number of Al moles reacted - 78.33 g / 27 g/mol = 2.901 mol
according to molar ratio
2 mol of Al forms - 3 mol of H₂
therefore 2.901 mol of Al - forms 3/2 x 2.901 = 4.352 mol
molar volume states that 1 mol of any gas occupies a volume of 22.4 L at STP
if 1 mol occupies 22.4 L
then 4.352 mol occupies - 22.4 L/mol x 4.352 mol = 97.48 L
volume occupied by H₂ is 97.48 L
