i think the next is two nuclei and still together but that stage is not anaphase. Anaphase is when the sister chromatids are pulled apart
[Ar] 3d10 4s2 4p5 is the electron configuration of bromine
In the reaction as follows: NH2- + CH3OH → NH3 + CH3O−, NH2- is the Brønsted-Lowry base.
BRØNSTED-LOWRY BASE:
- According to Bronsted-Lowry definition of a base and acid, a base is substance that accepts an hydrogen ion or proton (H+) while an acid is a substance that donates a proton.
- According to this reaction given as follows: NH2 + CH3OH → NH3+ CH3O-
- NH2- is a reactant that accepts a hydrogen ion (H+) to become NH3+
- NH3+CH3OH is a reactant that donates hydrogen ion (H+)
- Since NH2- accepts a proton, this means that in the reaction as follows: NH2 + CH3OH → NH3 + CH3O−, NH2- is the Brønsted-Lowry base.

The balanced equation for the reaction is ;
2Zn + O2 —> 2ZnO
The stoichiometry of O2 to ZnO is 1:2
The mass of ZnO formed - 358.5 g
The number of moles formed - 358.5 g / 81.4 g/mol = 4.4 moles
Therefore number of O2 moles reacted = 4.4 moles /2 = 2.2 mol
Mass of O2 reacted = 2.2 mol x 32 g/mol = 70.4 g
