.....i don't understand the question sorry
a) Answer:
= 210,000 gram or 210 Kg
Explanation:
14 hr is equivalent to;
= 14 × 3600 s
But;
8.2x10^4 A = 8.2x10^4 Coulomb /second = 8.2x10^4 C/s
1 Faraday = 96485C
Molar mass of Li: 6.941 g/mol
Therefore;
{(8.2x10^4 C/s)×(14×3600s)×(6.941 g/mol)/(96485C/mol)}×70%
= 2.1x10^5 gram or 210 kg
b. Answer;
= 0.23 kWh/mol
Explanation and solution;
Energy per mole is given by;
(96485C/mol) × (8.4V) = 8.10x10^5 (J/mol)
= 8.10x10^5 (Ws/mol)
Divide by 3600s/h to get:
= 8.10x10^5 (Ws/mol)
= 225 Wh/mol
= 0.23 kWh/mol

Particles dissolved in them because water is universal solvent.
Mucus found in the bronchial tubes collects dirt and germs that get into your lungs . Tiny hairs called cilia work to sweep out the debris collected to keep your lungs clean.
