1. 9.36 moles S
2. 0.213 moles Al
<h3>Further explanation</h3>
Given
Reaction
2Al+3S⇒Al₂S₃
Required
moles of S
moles of Al
Solution
The reaction coefficient in a chemical equation shows the mole ratio of the compounds involved in the reaction (reactants or products)
From equation, mol ratio of Al₂S₃ : S = 1 : 3, so mol S :
= 3/1 x mol Al₂S₃
= 3/1 x 3.12
= 9.36 moles S
From equation, mol ratio of Al : S = 2 : 3, so mol Al :
= 2/3 x mol S
= 2/3 x 0.32
= 0.213 moles Al
Hi!
Why is second ionization energy larger than first ionization energy?
The reason second ionization energy is larger is because it takes more energy to remove an electron from a poistively charged ion than it does from an neutral atom.
Answer:
Electrons are the only subatomic particles that have a negative charge.
Water's high polarity
Water's attraction to other polar molecules
I hope this works!!
