Answer:
2.15 L
Explanation:
M(NaOCl) = 23.0 + 16.0 + 35.5 = 74.5 g/mol
120.3 g *1 mol/74.5 g = 1.615 mol NaOCl
0.750 M = 0.750 mol/L
1.615 mol * 1L/0.750 mol = 2.15 L
The mass of Copper electroplated is 68.76 g
<h3>What is electroplating?</h3>
The process of plating a metal onto another is known as electroplating.
It is often used to prevent corrosion of metal or for the decorative purposes
In this process, electric current is passed through an aqueous solution containing dissolved cations.
The dissolved cations are reduced developing a thin metal coating on the electrode.
At cathode,

Current, I = 14.5 A
Time, t = 4 hrs = 4×60×60 = 14400 sec
Charge, q = It = 14.5×14400= 208800 C
Copper metal deposited by 2×96487 C = 63.55 g
Copper metal deposited by 208800 C = 
= 68.76g
Hence, The mass of Copper electroplated is 68.76 g

Answer:
(a) 0.25 mol
(b) 0.11 mol
(c) 8.77 mol
Explanation:
(a)
We use the equation given by ideal gas which follows:
where,
P = pressure of the gas = 1.00 atm
V = Volume of the gas = 6.0 L
T = Temperature of the gas = 298 K
R = Gas constant =
n = number of moles = ?
Putting values in above equation, we get:

(b)
We use the equation given by ideal gas which follows:
where,
P = pressure of the gas = 0.296 atm
V = Volume of the gas = 6.0 L
T = Temperature of the gas = 200 K
R = Gas constant =
n = number of moles = ?
Putting values in above equation, we get:

(c)
We use the equation given by ideal gas which follows:
where,
P = pressure of the gas = 30 atm
V = Volume of the gas = 6.0 L
T = Temperature of the gas = 250 K
R = Gas constant =
n = number of moles = ?
Putting values in above equation, we get:

Answer:
A an ionic compound that completely dissolves in water, forming many ions
Explanati
The answer is to increase the surface area of the solute.
You see it dissolves faster because there is a lot more water touching it when it is has a higher surface area.This can be achieved by crushing
