For N2(g)+3h2(g) ←→ 2nh3(g) The equilibrium system described by this equation has= 3 reactant molecule(s) and= 2 product gas molecule(s).
Answer:
Polarity is a measure of molecule's electrical charge which means that molecule or it's groups can have a dipole moment and also make hydrogen bonds.
Explanation:
So in terms of polarity methanol is more polar then ethyl acetate due to it's higher dipole moment and that it is a stronger hydrogen bond acceptor and also can be a hydrogen bond donor. So if we add methanol to the elutioning system it becomes more polar because and our compound moves faster on tlc due to methanol providing some more hydrogen bonds to it and increasing dipole-dipole interactions.
Answer:
0.605 molal
Explanation:
molality is the amount of solute in a particular mass of solvent.
lets calculate the amount of benzene solute.
mass of benzene= 13.3g
molar mass of C6H6= 12*6 +1*6 =72+7=78g/mol
amount of benzene= mass/molar mass
=13.3/78
=0.1705mol
molality= amount of solute/mass of solvent in kg
mass of solvent=282g=0.282kg
molality = 0.1705/0.282
=0.605 molal
