Answer:
VC = 18
Explanation:
Since L is the midpoint and you have LV, you know that LC is also 9.
1 mole of NH42SO4 contains 42 moles of H. We take the 42 moles of H and multiply that times Avogadro's number (6.02x10^23) and get 2.5284x10^25 atoms of hydrogen
Answer:
Q = 25360.269 j
Explanation:
Given data:
Mass = 165 g
Initial temperature = 10.55 °C
Final temperature = 47.32°C
Energy absorbed = ?
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = T2 - T1
ΔT = 47.32°C - 10.55 °C
ΔT = 36.77 °C
Q = m.c. ΔT
Q = 165 g . 4.18 j/g.°C . 36.77 °C
Q = 25360.269 j
<u>Answer:</u> The layer from where particles of air escape into space is exosphere.
<u>Explanation:</u>
The atmosphere is divided into layers. There are 5 main layers of atmosphere, which are: Troposphere, Stratosphere, Mesosphere, Thermosphere and Exosphere.
- Troposphere is the lowest layer of the atmosphere where most of the weather occurs.
- Then comes the Stratosphere which is about 50 km above the Earth's surface. It contains most of the ozone which is present in the atmosphere.
- Then comes the Mesosphere which starts from 50 km and extends upto 85 km from the Earth's surface.
- Then comes the Thermosphere which starts from 90 km and extends to between 500 km and 1,000 km.
- Exosphere is the last layer of the atmosphere, through which anything escapes the atmosphere to space. This layer extends upto 10,000 km from the Earth's surface.
Hence, the layer from where particles of air escape into space is exosphere.
