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
Answer:
Corresponds to a covalent compound.
Explanation:
Both Boron and Fluorine are nonmetals, forming a covalent bond, the result of which is the boron trifluoride compound (BF3). This is a highly toxic gas.
It is synthesized by the reaction between hydrogen fluoride and boron oxide:
B2O3 + 6 HF → 2 BF3 + 3 H2O
151 L
V1/T1 = V2/T2
V1 = 95 L
T1 = 110 K
T2 = 175 K
Solve the equation for V2 —> V2 = V1T2/T1
V2 = (95 L)(175 K) / (110 K) = 151 L
Answer:
the answer is
<em><u>C. to collect rock samples from the moon</u></em>
I swear I did't copy off of the first person I just took the test and at the end went I completed the test it showed me the real answer.
I hope that this is helpful for you
