<span>When ammonium is dissolved in wated, we have,
NH3 + H2O >> NH4+ + OHÂŻ
pOH = -log[OH-]
pOH = -log[2.25x10^-2]
pOH = 1.6478
Since pH + pOH=14. Therefore pH = 14 - pOH = 14 - 1.648 = 12.3522.
[H+]=10^-pH
[H+]=10^(-12.3522)
[H+]= 4.3250 * 10 ^(-5)</span>
Data Given:
Time = t = ?
Current = I = 10 A
Faradays Constant = F = 96500
Chemical equivalent = e = 107.86/1 = 107.86 g
Amount Deposited = W = 17.3 g
Solution:
According to Faraday's Law,
W = I t e / F
Solving for t,
t = W F / I e
Putting values,
t = (17.3 g × 96500) ÷ (10 A × 107.86 g)
t = 1547.79 s
t = 1.54 × 10³ s
The Arrhenius acid is a compound that release hydrogen ion (H⁺) when being dissolved in water.

Answer:</h3>
9,729.73 L
<h3>
Explanation:</h3>
- Based on Boyle's law when temperature is held constant then the volume of a fixed mass of a gas, V is inversely proportional to Pressure, P.
- That is; Pα 1/V
- Mathematically, P= k/V where k is a constant
- Therefore, when the volume of a gas and the pressure are altered,
- P1V1=P2V2 = k, where P1 and P2 are the initial and final pressure respectively while V1 and V2 are the initial and final pressure respectively.
In this case;
Initial Pressure, P1 = 150 atm
Initial volume, V1 = 60.0 L
Final pressure, P2 = 0.925 atm
we are required to calculate the final volume
But, P1V1 =P2V2
Rearranging the formula, V2 = P1V1 ÷ P2
Thus;
V2 =(150 atm × 60.0 L) ÷ 0.925 atm
= 9,729.73 L
The new volume will be 9,729.73 L
