Answer:
T2 = 29.79°C
Explanation:
Equliibrium signifies that heat loss = heat gained
Heat gained by Ice;
H = ML
Mass, M = Number of moles * Molar mass = 1 * 18 = 18g
l = 6.01 k J m o l = 334 J/g
C = 4.186 J/g
H = 18(334)
H = 6012
Heat lost by water
H = MCΔT
H = 18 * 4.186 * (50 - T2)
H = 3767.4 - 75.348T2
Since H = H, we have;
6012 = 3767.4 - 75.348T2
- 75.348T2 = 3767 - 6012
T2 = 2245 / 75.348
T2 = 29.79°C
a chemical property of iron is the ability to change it, hammer it, roll it, shape it etc
Answer:
B. HCN
Explanation:
PCN stands for Parent Country National. A PCN is an individual who is working in the country other than his or her native or origin country.
HCN stands for Host Country National. A HCN is the employee of the organization who is a citizen of the country where the foreign subsidiary is been located.
TCN stands for Third Country National. A TCN is an individual of other nation who is hired by a government who represents neither his host country or the government.
Hence in the context, a person who returns to his native country and works at an MNE which have its headquarter in the country where the individual studied is termed as a Host Country National or HCN.
Thus the correct option is (B).

Answer:
The new volume is 8.64 L.
Explanation:
Charles's Law consists of the relationship that exists between the volume and the temperature of a certain quantity of ideal gas, which is maintained at a constant pressure. For a given sum of gas at constant pressure, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases.
In summary, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the quotient that exists between the volume and the temperature will always have the same value:
![\frac{V}{T} =k](https://tex.z-dn.net/?f=%5Cfrac%7BV%7D%7BT%7D%20%3Dk)
Being an initial state 1 that modifies its conditions until a final state 2, it is fulfilled:
![\frac{V1}{T1} =\frac{V2}{T2}](https://tex.z-dn.net/?f=%5Cfrac%7BV1%7D%7BT1%7D%20%3D%5Cfrac%7BV2%7D%7BT2%7D)
In this case:
- V1= 8 L
- T1= 326 K
- V2= ?
- T2= 352 K
Replacing:
![\frac{8L}{326 K} =\frac{V2}{352 K}](https://tex.z-dn.net/?f=%5Cfrac%7B8L%7D%7B326%20K%7D%20%3D%5Cfrac%7BV2%7D%7B352%20K%7D)
Solving:
![V2=352 K*\frac{8L}{326 K}](https://tex.z-dn.net/?f=V2%3D352%20K%2A%5Cfrac%7B8L%7D%7B326%20K%7D)
V2= 8.64 L
<u><em>The new volume is 8.64 L.</em></u>
