Hello I took this test just now and got 100% your correct answer would be C. Hope this helps.
Mitosis results in two identical daughter cells, whereas meiosis results in four cells.
Answer:
0.429 J/g.°C
Explanation:
Step 1: Calculate the heat absorbed by the water (Qw)
We will use the following expression.
Q = c × m × ΔT
where,
c: specific heat capacity
m: mass
ΔT: change in the temperature
Qw = 4.184 J/g.°C × 150. g × (29.8°C-25.0°C) = 3012 J
Step 2: Calculate the heat released by the sample of nickel
According to the law of conservation of energy, the sum of the heat lost by the sample of nickel and the heat absorbed by the water is zero.
Qw + QNi = 0
QNi = -Qw = -3012 J
Step 3: Calculate the specific heat capacity of nickel
We will use the following expression.
QNi = c × m × ΔT
c = QNi/m × ΔT
c = -3012 J/100.0 g × (29.8°C-100.0°C) = 0.429 J/g.°C
