Answer:
RbOH → Rb⁺ + OH⁻
As the hydroxide can gives the OH⁻ in water, it is considered as an Arrhenius's base
Explanation:
Arrhenius theory states that a compound is considered a base, if the compound can generate OH⁻ ions in aqueous solution.
Our compound is the RbOH.
When it is put in water, i can dissociate like this:
RbOH → Rb⁺ + OH⁻
As the hydroxide can gives the OH⁻ in water, it is considered as an Arrhenius's base
The balanced chemical equations are as follows:
- AlBr₃ + K → 3 KBr + Al
- FeO + PdF₂ → FeF₂ + PdO
- P₄ + 6 Br₂ → 4 PBr₃
- 2 LiCl + Br₂ → 2 LiBr + Cl₂
<h3>What are balanced chemical equations?</h3>
Balanced chemical equations in which the moles of atoms of elements taking part in a reaction are balanced on both sides of the equation.
The balancing of chemical equations follows the law of conservation of mass which states that matter can neither be created nor destroyed.
In balancing of chemical equations, the following steps are follows:
- ensure that the all the substances involved are written in the equation
- do not alter the formula of compounds or molecules
- add numerical coefficients in front of the compounds and molecules to ensure that the moles of atoms of elements are balanced on both sides of the equation
In conclusion, a balanced chemical equation obeys the law of conservation of mass.

Moles Li = 3.50 g / 6.941 g/mol= 0.504
the ratio between Li and N2 is 6 : 1
moles N2 required = 0.504 /6=0.0840
we have 3.50 g / 28.0134 g/mol=0.125 moles of N2 so N2 is in excess
the ratio between Li and Li3N is 6 : 2
moles Li3N = 0.504 x 2 /6=0.168
mass Li3N = 0.168 mol x 34.8297 g/mol=5.85 g
