Bonds formed between atoms can be classified as ionic and covalent
Ionic bonds are formed between atoms that have a high difference in the electronegativity values.
In contrast, bonds formed between atoms that have a difference in electronegativity lower than the ionic counterparts are polar covalent bonds. If the atoms have very similar electronegativities, they form non-polar covalent bonds.
In H2S, the S atom is bonded to 2 H atoms. The electronegativity of H = 2.2 and S= 2.56. Since the difference is not high the bond formed will be covalent (polar covalent).
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>
