Answer:
24 hours
Explanation:
The computation is shown below:
The needed mole of is
= 5 ÷22.4 = n
Also 1 mole of required four electric charge
Now the charge needed is
= n × 4 × 96,500 C
= 4 × 96,500 × 5 c ÷ 22.4
= 86160.714 C
Now
q = i t
t = q ÷ i
= 86160.714 C ÷ 0.995
= 86593.7 seconds
= 24 hours
Hence, the correct option is A.
The answer for the following problem is mentioned below.
- <u><em>Therefore the final temperature of the gas is 740 K</em></u>
Explanation:
Given:
Initial pressure of the gas () = 1.8 atm
Final pressure of the gas () = 4 atm
Initial temperature of the gas () = 60°C = 60 + 273 = 333 K
To solve:
Final temperature of the gas ()
We know;
From the ideal gas equation;
we know;
P × V = n × R × T
So;
we can tell from the above equation;
<u> P ∝ T</u>
(i.e.)
<em> </em><em> = constant</em>
=
Where;
= initial pressure of a gas
= final pressure of a gas
= initial temperature of a gas
= final temperature of a gas
=
=
= 740 K
<u><em>Therefore the final temperature of the gas is 740 K</em></u>
