Answer:
The new temperature is 1596 C.
Explanation:
Charles's Law indicates that 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.
Statistically, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the ratio that exists between the volume and the temperature will always have the same value:
Being an initial state 1 and a final state 2, it is fulfilled:
In this case:
- V1= 25 L
- T1= 350 C= 623 K (being 0 C= 273 K)
- V2= 75 L
- T2= ?
Replacing:
Solving:
T2= 1869 K= 1596 C
<u><em>The new temperature is 1596 C.</em></u>

Answer:
The freezing point of the solution is -1.4°C
Explanation:
Freezing point decreases by the addition of a solute to the original solvent, <em>freezing point depression formula is:</em>
ΔT = kf×m×i
<em>Where Kf is freezing point depression constant of the solvent (1.86°C/m), m is molality of the solution (Moles CaBr₂ -solute- / kg water -solvent) and i is Van't Hoff factor.</em>
Molality of the solution is:
-moles CaBr₂ (Molar mass:
189.9g ₓ (1mol / 199.89g) = 0.95 moles
Molality is:
0.95 moles CaBr₂ / 3.75kg water = <em>0.253m</em>
Van't hoff factor represents how many moles of solute are produced after the dissolution of 1 mole of solid solute, for CaBr₂:
CaBr₂(s) → Ca²⁺ + 2Br⁻
3 moles of ions are formed from 1 mole of solid solute, Van't Hoff factor is 3.
Replacing:
ΔT = kf×m×i
ΔT = 1.86°C/m×0.253m×3
ΔT = 1.4°C
The freezing point of water decreases in 1.4°C. As freezing point of water is 0°C,
<h3>The freezing point of the solution is -1.4°C</h3>

Answer:
Hi
Inbreeding increases the chances of transmission to the next generation of types of inherited diseases. Our genome is made up of two copies of each gene, one inherited from our father and one from our mother. In order for autosomal recessive diseases to be found, the two copies of the gene need to be mutated. If only one of the copies is mutated and the other is not, the person is a carrier but does not manifest any of the clinical symptoms of the disease. One of these diseases is hemophilia. An example of this is Prince Leopold, he was the first real member affected by hemophilia, in this case hemophilia B. When one of the proteins necessary for blood clotting is missing, the wounds take much longer to heal. Small cuts are not usually a problem, but major injuries can cause bleeding.
The defective gene in people who suffer from this type of hemophilia is called F9, and it is located on the X chromosome. That means it has an inheritance linked to sex. Women have two X chromosomes (XX), while men have an X chromosome and one Y (XY). Since hemophilia alleles are recessive, two defective alleles are needed in women to suffer from the disease, while only one is needed in men. Therefore, the disease is much more common in men. The most frequent hemophilia is that of type A and is due to a defect in coagulation factor VIII, whose gene also has an inheritance linked to sex.
