Latent heat released during condensation offsets some of the cooling of a rising air parcel, causing the moist adiabatic lapse rate to have a smaller value.
Answer:Nothing, the photon just bounces off the surface.
Explanation:
According to Albert Einstein, a photoelectron can only be emitted from a metal surface when the energy of the incident photon is greater than the work function of the metal.
In the scenario described in the question, the work function of the metal is greater than the energy of the photon. Hence, the photon just bounces off the metal surface without emitting any electron.
The gas, 2 mol of H2, occupies the highest volume at STP since at STP the volume of this gas is approximately 44.8 mol as compared to other options this has the greatest amount.
Answer : The moles of 
formed are, 22.3 moles.
Explanation : Given,
Moles of 
= 16.72 mol
The given chemical reaction is:
From the balanced chemical reaction, we conclude that:
As, 3 moles of react to give 4 moles of
So, 16.72 moles of react to give 
moles of
Therefore, the moles of formed are, 22.3 moles.
Answer:
Explanation:
Endothermic reactions absorb energy from the surrounding, but exothermic reactions release energy to the surrounding.
