Answer:
The final temperature of the mixture is 44.9°C
Explanation:
Mass of the substance (gold) = 2.575g
Specific heat capacity of gold = 0.129J/g°C
Initial temperature (T1) = 75°C
Final temperature (T2) = ?
Energy lost = 10J
Heat energy(Q) = MC∇T
Q = heat energy (in this case lost)
M = mass of the substance
C = specific heat capacity of the substance
∇T = change in temperature of the substance = (T2 - T1)
Q = MC∇T
Q = MC(T2 - T1)
-10 = 2.575 × 0.129 × (T2 - 75) energy is -ve because it was energy lost.
-10 = 0.3321 × (T2 - 75)
-10 = 0.3321T2 - 24.9075
Collect like terms
0.3321T2 = 24.9075 - 10
0.3321T2 = 14.9075
T2 = 14.9075 / 0.3321
T2 = 44.88
T2 = 44.9°C
The final temperature of the mixture is 44.9°C
This would be difficult to specify for you because you did not provide the genotype of the other parent. However, there are limitations to the possible combinations, so I will do each to help you out.
<u>1st possibility:</u>
<u>B B</u>
B BB BB
b Bb Bb
Brown eyes: 4 out of 4 or 100%
Blue eyes: 0 out of 4 or 0%.
<u>2nd possibility:</u>
<u>B b</u>
B BB Bb
b Bb bb
Brown eyes: 3 out of 4 or 75%
Blue eyes: 1 out of 4 or 25%.
<u>3rd possibility:</u>
<u>b b</u>
B Bb Bb
b bb bb
Brown eyes: 2 out of 4 or 50%
Blue eyes: 2 out of 4 or 50%.
<u>As long as there is a capital letter in the genotype, the dominant trait will come out. So if the combination is </u><u>Bb or BB</u><u>, then </u><u>BROWN </u><u>in this case will come out. The only time </u><u>BLUE eyes </u><u>will come out is if has two recessives in its genotype or </u><u>bb.</u>
Mg + Cl₂ -----> MgCl₂
24g 1 mol
24g Mg ---- 1 mol Cl₂
Xg Mg ------ 2 mol Cl₂
X = 2×24
<u>X = 48g Mg</u>
