The lead acid battery produces energy by oxidation of lead. The amount of lead oxidized in this case is 1.47 g.
<h3>What is lead acid battery?</h3>
The lead acid battery is the common accumulator that we have in use. It is made up of a cell that contains lead electrodes in an acid.
The oxidation of lead occurs according to thr equation;
Pb(s) ----> Pb^2+(aq) + 2e
If 207 g of Pb is oxidized by 2(96500)C
x g of lead is oxidized by (221 * 6.20) C
x = 207 g * (221 * 6.20) C/2(96500)C
x = 1.47 g

Answer: option C) Na, Mg, K
Explanation:
Similar chemical properties are expressed by elements found in the same or close groups. There are Seven (7) groups in the Periodic table.
Of all the options, ONLY sodium Na, Magnesium Mg, and Potassium K, are located in closely together with SODIUM and MAGNESIUM being in the Same period, while SODIUM and POTASSIUM are placed in the same Group 1.
Therefore, Na, My, and K are most similar in chemical properties
Answer:
.094 M
Explanation: 0.32molNaCl/ 3.4L = .094M
D. It is the heat required to change a gram of substance from a liquid to a gas.
Explanation:
The heat of vaporization is the heat required to change a gram of substance from a liquid to a gas.
- It is also known as the enthalpy of vaporization.
- The heat of vaporization is the quantity of heat needed to change one gram of a substance from liquid to gas.
- This heat of vaporization is dependent on the pressure conditions the process is taking place.
- Different liquids have their heat of vaporization.
