Answer:
B
Explanation:
I looked it up and found the answer lol
Shielding effect being attendency of the inner electrons to repel the outermost electrons, an increase in shielding effect increases atomic radius and decrease reduces the atomic radius
Answer:
B mixture can be separated by physical means
Answer:
Rate = −1/2 Δ[N2O] / Δt = 1/2 Δ[N2]/ Δt = Δ[O2]/Δt
Explanation:
Based on the reaction:
2 N2O(g) → 2 N2(g)+O2(g)
The rate of reaction is the change in concentration per mole of reaction.
In this problem, 2 moles of N₂O are consumed, the rate per mole of reaction is:
Rate = -1/2 Δ[N₂O] / Δt
<em>Negative because this reactant is consumed</em>
In therms of N₂:
Rate = 1/2 Δ[N₂] / Δt
<em>1/2 because 2 moles are produced per mole of reaction</em>
And for O₂:
Rate = Δ[O₂] / Δt
Right solution is:
<h3>Rate = −1/2 Δ[N2O] / Δt = 1/2 Δ[N2]/ Δt = Δ[O2]/Δt</h3>
