Answer:
Explanation:
Edit the reaction by drawing all steps in the appropriate boxes and connecting them with reaction arrows. Add charges where needed. Electron flow arrows should start on the electron(s) of an atom or a bond and should end on an atom, bond, or location where a new bond should be created. Include all free radicals by right-clicking on an atom on the canvas and then using the Atom properties to select the monovalent radical.
Answer:
+5
Explanation:
Let's consider the following balanced equation.
Mn(NO₃)₂ + 2 HCl --> MnCl₂ + 2 HNO₃
We can determine the oxidation number of N in (NO₃)₂²⁻ taking into account that the sum of the oxidation numbers of the elements present in a chemical species is equal to this overall charge. For this compound we know:
- The oxidation number of O is -2.
- The overall charge is 2-.
- We have 2 atoms of N and 2× 3 = 6 atoms of O.
2 N + 6 O = 2-
2 N + 6 (-2) = 2-
2 N = +10
N = +5

The correct formula : BeSO₄
<h3>Further explanation</h3>
Chemical formula shows the composition number of the constituent atoms
Polyatomic ion consists of 2 or more ions
The equal charge of the two ions will cancel each other out, while the different charges of the two ions will be crossed each other
Be²⁺ (monatomic ion) has a positive charge of +2, while SO₄²⁻ (polyatomic ion) has a negative -2 charge, so that the two charges with the same magnitude but with different charges cancel each other out so that the compound form is BeSO4
