Molar mass of COH1206 is 1243.5857 g/mol

Bohr's model is one of the ea.rliest model of atom in history, modified from Ruth.erford's model.
In 1913, a D.anish physi.cts, Niels Bohr refi.ned Ruth.erford model of the atom. How.ever, he disco.vers that elec.tron can only have spe.cific amo.unts of energy. These energy levels are also known as ele.ctron shells.
As for the Lewis Dot Structure, it is the m.odel of an atom that has the che.mical symbol for the ele.ment surronded by dots to rep.resent the valence ele.ctron of the ele.ment.

HOPE IT HELPS
PLEASE MARK ME BRAINLIEST ☺️
I am pretty sure it is B. If it turns litmus paper red it is acidic. The other 2 make no sense.
I might be wrong tho.
Hope that helped☺️
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>
