Explanation:
The molar mass of the compounds are incorrect
Answer:
5 g
Explanation:
The heat required to vaporize ice is the sum of
i) Heat required to melt ice at 0°C
ii) Heat required to raise the temperature from 0°C to 100°C
iii) Heat required to vaporize water at 100°C
Thus;
H = nLfus + ncθ + nLvap
H= n(Lfus + cθ + Lvap)
Lfus = 6.01 kJ/mol
Lvap = 41 kJ/mol
c = 75.38
n =?
2100 = n(6.01 + 75.38(100) + 41)
n = 2100 KJ/7585.01 kJ/mol
n = 0.277 moles
Mass of water = number of moles * molar mass
Mass of water = 0.277 moles * 18 g/mol
Mass of water = 5 g
Definitely their jawline… just kidding, it’s how much they dissociate
B) convection
Explanation:
Once the sun's energy reaches the earth's atmosphere by radiation, it is circulated within the atmosphere and oceans through convection.
The energy of the sun on earth is moved between the ocean and the atmosphere by air around us.
- Heat transfer in fluids is by convection.
- It involves the actual motion of the particles of medium from one place to another due to differences in temperature and density.
- Air close to the surface of the ocean is less dense and hot due to high temperature.
- The air rises and it is replaced by colder air masses.
- This exchange leads to the development of convective cells.
- This moves the energy of the sun between the atmosphere and the ocean surface.
