2. The diagram shows a Zn/MnO2-KOH alkaline dry cell. In your response, do the following: • Label all parts. • Label the cathode and the anode, including the charges on each. • Show the flow of electrons. • Explain how the cell works. Include the oxidation and reduction half-reactions in your explanation.

Tin has ten stable isotopes. the heaviest, 124sn, makes up 5.80% of naturally occuring tin atoms. how many atoms of 124sn are present in 82.0 g of naturally occurring tin? what is the total mass of the 124sn atoms in this sample?
