Answer:
B => Mg° => Mg⁺² + 2e⁻
Explanation:
2Mg° + O₂ => 2MgO rewrite => Mg° + 1/2O₂ => 2MgO
Oxidation Half Rxn => Mg° => Mg⁺² + 2e⁻
Reduction Half Rxn => 1/2O₂ + 2e⁻ => 2O⁻
__________________________________-
FYI Note => For half-reactions one always finds the electrons listed on the product side of the reaction for oxidation reactions and for reduction reactions on the reactant side.
Answer:
2.6166 moles
Explanation:
stp means: T=273k p=101.3kpa
R= 8.31(constant) v=58.6
using the ideal gas law; pv=nRt
101.3 x 58.6 = n x 8.31 x 273
n= (101.3 x 58.6)\(8.31 x 273)
n= 2.6166moles
Its location is in the nucleus, because the particle is a proton or a neutron.
Explanation:
In a magnetic field, the radius of the charged particle is as follows.
r = 
where, m = mass, v = velocity
q = charge, B = magnetic field
Therefore, q will be calculated as follows.
q = 
= 
= 
= 
= +2e
Thus, we can conclude that the charge of the ionized atom is +2e.
