Mass of Aluminum= 8.829 g
<h3>Further explanation</h3>
Given
Reaction
2Al + 6HCl → 2AlCl₃ + 3H₂
Required
mass of Aluminum
Solution
At STP, 1 mol gas = 22.4 L
For 11 L of Hydrogen :
= 11 : 22.4
= 0.491
From equation, mol ratio Al : H₂ = 2 : 3, so mol Al :
= 2/3 x mol H₂
= 2/3 x 0.491
= 0.327
Mass Aluminum(Ar=27 g/mol) :
= 0.327 mol x 27 g/mol
= 8.829 g
it's 3 dollars per 12 eggs so 3/12
simplify 3/12 by dividing both numbers by 3 so you get 1/4
you should know what 1/4 of a dollar is
or think of it this way 12 eggs are 3 dollars so every 4 eggs is one dollar. divide 1 dollar by 4 eggs

Answer: Potassium to fluorine, fluorine to nitrogen, bromine to hydrogen, carbon to hydrogen, lithium to chlorine, sodium to chlorine.
Explanation:
Ionic bond is greater when the electronegativity difference existing between the two atoms are large causing the bonding to be more polar.
