Your question, I guess, How do vapour and gases differ...
Answer:
1.) Vapour is the changed state of any liquid either due to boiling or evaporation
2.) Vapour are more energetic as they have absorbed the latent heat of vaporization whereas Gases are low in energy because they are already in gaseous form at room temperature.
3.) Vapour have boiling points above room temperature while gases have their boiling point below room temperature.
Answer:
How many atoms of each element are there in one molecule of H3PO4? there are 8 atoms in total in H3PO4. there are 3 atoms of hydrogen, 1 atom of phosphorous and 4 atoms of oxygen in the one molecule of this compound, which is called hydrogen phosphate.
The change in heat is simply equal to:
change in heat ΔH = final enthalpy – initial enthalpy
ΔH = [280.25 g * 4.18J/gC * (17.5°C)] – [280 g * 4.18J/gC
* 13.5°C]
ΔH = 4,699.89 J = 4.7 kJ
<span>Hence heat released is about 4.7 kJ</span>
Answer:
hydrogen are converted into energy I dont know other
