Answer:
Pencil is always used to mark chromatography paper or TLC plates because ink may run and interfere with the chromatogram. ... As soon as the paper/plate is taken out, mark the solvent front with a pencil before the solvent evaporates and the front becomes impossible to see.
Nonmetals is most likely the answer
Answer:
Following are the responses to this question:
Explanation:
They can measure the spontaneity of the reaction with the form,
Substituting the values of
in the above expression information mostly on the playfulness of the reaction would be given to us from the expression above. This reaction is spontaneous if the price of
is negative, and if it is positive the response is not random. At equilibrium, the values of
are 0.
Answer:
1.) 9 carbon atoms, only
Explanation:
Prefix: non- simply means 9.
Suffix: -ene means double bond, -yne means triple bond, and -ane means single bonded carbons.
Answer:
The heat of vaporisation of methanol is "3.48 KJ/Mol"
Explanation:
The amount of heat energy required to convert or transform 1 gram of liquid to vapour is called heat of vaporisation
When 8.7 KJ of heat energy is required to vaporize 2.5 mol of liquid methanol.
Hence, for 1 mol of liquid methanol, amount of heat energy required to evaporate the methanol is = 
= 3.48 KJ
So, the heat of vaporization 
Therefore, the heat of vaporization of methanol is 3.48KJ/Mol
