Answer:
You didn't give any options/statements, so I'm just going to give you context on what catalysts does. Catalysts decrease the activation energy needed, allowing more particles for successful reactions.
I know my colleague tried doing an experiment by using hydrogen peroxide as a catalyst and seeing how rates of reactions were affected. It ended up with a stain on our chemistry lab and him re-doing his entire lab.
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
Alpha and beta particles, I saw this somewhere, but I can't remember where
Chemical because its mixing two chemicals which are substances
