FE is iron
iron is an element
so the answer is element 0-0
Sodium loses an electron and chlorine gains an electron.

Answer:
2. 100 times more hydroxide ions,
Explanation:
Acidity and alkalinity are measured with a logarithmic scale called pH. Each one-unit change in the pH scale corresponds to a ten-fold change in hydrogen ion concentration. Therefore, a 1.0 liter aqueous solution with a pH of 5.0 contains 100 times more hydronium ions than a 1.0 liter aqueous solution with a pH of 7.0
You can reduce the charges and subscripts so it is PbS2
The correct answer is option 4. The conversion of energy is from chemical to electrical energy. Voltaic cells are driven by a spontaneous reaction that produces an electric current. Voltaic cells are a type of electrochemical cell.
