Answer:
Kush would have been able to fight better and probably would have never been invaded by Egypt, and they could have beaten the Assyrians when they tried to takeover Egypt. And the 25th dynasty would have continued.
Explanation:
that is my explanation and answer^
Answer:
1835 J
Explanation:
There are three heat flows in this question.
Heat lost by Fe + heat gained by water + heat gained by calorimeter = 0
q₁ + q₂ + q₃ = 0
m₁C₁ΔT₁ + m₂C₂ΔT₂ + q₃ = 0
Data:
m₁ = 65.06 g
C₁ = 0.450 J·°C⁻¹g⁻¹
Ti = 100.0 °C
T_f = 23.59 °C
m₂ = 32.49 g
C₂ = 4.184 J·°C⁻¹g⁻¹
Ti = 20.63 °C
T_f = 23.59 °C
Calculations:
(a) Heat lost by iron
ΔT₁ = 23.59 °C - 100.0 °C = -76.41 °C
q₁ = m₁C₁ΔT₁ = 65.06 g × 0.450 J·°C⁻¹g⁻¹ × (-76.41 °C) = -2237 J
(b) Heat gained by water
ΔT₂ = 23.59 °C - 20.63 °C = 2.96 °C
q₂ = m₂C₂ΔT₂ = 32.49 g × 4.184 J·°C⁻¹g⁻¹ × 2.96 °C = 402 J
(c) Heat gained by calorimeter
-2237 J + 402 J + q₃ = 0
-1835 J + q₃ = 0
q₃ = 1835 J
The heat gained by the calorimeter was 1835 J.
answer:
I think nine
explanation:
Nuclear fission : It is defined as the splitting of bigger nuclei into two smaller nuclei. During this process neutrons and some energy also released.
Hey there!:
Density = 0.789 g/mL
Mass = 0.0027 g
Volume = ?
Therefore:
D = m / V
0.789 = 0.0027 / V
V = 0.0027 / 0.789
V = 0.00342 mL
hope this helps!
