Answer:
mass of S₈ = 96.1146 grams
Explanation:
The balanced equation that describe the reaction is as follows:
8 Fe + S₈ ..............> 8 FeS
From the equation, we can note that:
8 moles of Fe react with 1 mole of S₈
This means that:
8 * 55.8 grams of iron react with 8 * 32 grams of S₈.
To know the mass of S₈ that will react with 167.6 grams of Fe, we will simply do cross multiplication as follows:
mass of S₈ = (167.6 * 8 * 32) / (8 * 55.8)
mass of S₈ = 96.1146 grams
Hope this helps :)
Answer:
Option B
Explanation:
As Brønsted-Lowry theory states, acids are the ones that can donate protons.
When a proton is donated, it is released to become medium more acidic.
HCl is a strong acid.
HCl (l) + H₂O (l) → H₃O⁺ (aq) + Cl⁻(aq)
These always reffers to strong acid where the dissociation is 100% completed.
In a weak acid, dissociation is not 100% complete, that's why we have an equilibrium.
HA (l) + H₂O (l) ⇄ H₃O⁺ (aq) + A⁻(aq) Ka
Answer:
