Answer:

It cools down

Explanation:

The expansion valve lowers down the pressure of the refrigerant (in liquid form). This allows the refrigerant to expand. As the refrigerant expands the heated molecules in it get spread to a larger area and thus the oscillatory vibrations in the molecules get reduced there by reducing the kinetic energy ( KE )and thus the heat. Also sometimes spray of Aerosols are used to cool down the refrigerant.

In an electroplating process, copper (ionic charge +2e, atomic weight 63.6 g/mol) is deposited using a current of 10.0 A. What m

salantis [7]

Answer : The mass of copper deposit is, 1.98 grams

Explanation :

First we have to calculate the charge.

Formula used : $Q=I\times t$

where,

Q = charge = ?

I = current = 10 A

t = time = 10 min = 600 sec (1 min = 60 sec)

Now put all the given values in this formula, we get

$Q=10A\times 600s=6000C$

Now we have to calculate the number of atoms deposited.

As, 1 atom require charge to deposited = $2\times (1.6\times 10^{-19})$

Number of atoms deposited = $\frac{(6000)}{2\times(1.6\times 10^{-19})}=1.875\times 10^{22}$ atoms

Now we have to calculate the number of moles deposited.

Number of moles deposited = $\frac{(1.875\times 10^{22})}{(6.022\times 10^{23})}=0.03113$ moles

Now we have to calculate the mass of copper deposited.

1 mole of Copper has mass = 63.5 g

Mass of Copper Deposited = $63.5\times 0.03113 =1.98g$

Therefore, the mass of copper deposit is, 1.98 grams

The best fit curve line to an absorbance vs. concentration plot for standard solutions of a dye has a slope of 0.1815 mL/mg and

omeli [17]

Answer:

The concentration of dye is 2.29 mg/mL.

Explanation:

According to Beer's law the absorbance (A) of a solution is proportional to its concentration (c). The best fit curve line to an A vs. c plot has a slope of 0.1815 mL/mg and intercept of 0.0477. The resulting equation is:

A = 0.0477 + 0.1815 mL/mg . c

If a solution has an absorbance of 0.464, the concentration of dye will be:

0.464 = 0.0477 + 0.1815 mL/mg . c

c = 2.29 mg/mL
