Answer: MgS, MgBr_2, V_2S_5 and VBr_5 are four binary ionic compounds that could be formed.

Explanation:

For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.

Mg is having an oxidation state of +2 called as Mg^{2+} cation and S^{2-} is an anion with oxidation state of -2. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral MgS. Also Mg^{2+} cation and Br^{-} can combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral MgBr_2.

Also Vanadium is having an oxidation state of +5 called as V^{5+} cation and S^{2-} is an anion with oxidation state of -2. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral V_2S_5. Also V^{5+} cation and Br^{-} anion can combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral VBr_5.

Zigmanuir [339]

Answer:

C. Na⁺ is entering the cell.

Explanation:

In the depolarization phase, the permeability of sodium ions (Na⁺) increases, allowing a large flow of sodium ions to enter the cell through the membrane by simple diffusion.

This process causes intracellular liquids to be <u>positively</u> charged due to the large amount of cations.

Stels [109]

Answer:

Increases

Explanation:

Atomic size is the amount of space between the nucleus of an atom and the outermost electron. So, as each additional energy level is added, the overall amount of space between the nucleus and the outermost electron increases because there is now an extra shell of electrons that is farther out.
