The balanced equation is Mg + 2AgNO₃ ⟶ Mg(NO₃)₂ + 2Ag

Step 1. Write the unbalanced equation

Mg + AgNO₃ ⟶ Mg(NO₃)₂ + Ag

Step 2. Start with the most complicated-looking formula [Mg(NO₃)₂] and balance its atoms.

Mg: Already balanced —1 atom each side.

N: We need 2 N on the left. Put a 2 in front of AgNO₃.

1Mg + 2AgNO₃ ⟶ 1Mg(NO₃)₂ + Ag

O: Already balanced —6 atom6 each side.

Step 3: Balance Ag

We have 2Ag on the left. We need 2Ag on the right.

1Mg + 2AgNO₃ ⟶ 1Mg(NO₃)₂ + 2Ag

stealth61 [152]

Answer:

Calcium ions.

Explanation:

The generation of the action potential helps in the transfer of information to the different body parts. This potential occurs to the difference in membrane potential inside and outside of the cell.

The sarcoplasmic reticulum is the homologous to the endoplasmic reticulum of the cells. The sarcoplasmic reticulum contains calcium ions in it and releases the stored calcium ions on the generation of the action potential. This calcium ion is important for the action of the actin and myosin.

Thus, the correct answer is option (D).
