I think the correct answer from the choices listed above is option D. The correct mass of nitrogen would be 2.9 g. The mass is calculated by multiplying the density and the volume of the substance. The correct answer should have two significant figures since it is the least precise operation.
UV rays, gamma rays, and x rays
Hope this help
Answer: 1.33x10^-22g
Explanation:Please see attachment for explanation
Answer:
B) -1551 kJ
Explanation:
There are two heat flows in this question.
Heat released by engine + heat absorbed by water = 0
q₁ + q₂ = 0
q₁ + mCΔT = 0
Data:
m = 2.51 kg
C = 3.41 J°C⁻¹g⁻¹
T_i = 23.8 °C
T_f =205 °C
Calculations:
(a) ΔT
ΔT = 205 °C - 23.8 °C = 181.2 °C
(b) q₂
q₂ = mCΔT = 2510 g × 3.41 J·°C⁻¹g⁻¹ × 181.2 °C = 1.551× 10⁶ J = 1551 kJ
(c) q₁
q₁ + 1551 kJ = 0
q₁ = -1551 kJ
The exploration of the mid-cayman rise is intended to discover that what life may have been like before the evolution of photosynthesis.
<h3>What is mid - cayman rise?</h3>
Mid - cayman rise is an area or era where only some amount of light is coming but still existence of life is present there.
As we know that plants make their own food by the process called photosynthesis in the presence of light, but this is not the scenario for all the time. Before the discovery of photosynthesis plants also prepared their own food.
Hence, option (a) is correct.
