Okay so, 24.00 mL of a 0.25 M NaOH solution is titrated.
Answer: norfenefrine 
Explanation:
Depression in freezing point is given by:
= Depression in freezing point
i= vant hoff factor = 1 (for non electrolyte)
= freezing point constant = 
m= molality
Weight of solvent (ethanol)= 
Molar mass of unknown non electrolyte = M g/mol
Mass of unknown non electrolyte added = 82 mg = 0.082 g (1g=1000mg)
The molecular mass of norfenefrine is near to 154 and thus the identity of the white powder is norfenefrine .
Answer: the graph of Charles' law is a graph that passes through the origin in which as one variable increases, the other also increases and vice versa.
Explanation:
Answer:
Molecules are made of atoms.
Answer:
differing electronegativity
Explanation:
the electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.
in ionic bond one of the 2 atoms attract the electrons from the another and don't share it so the electronegativity must be different to make the attract tendency different.
so,
first, when we speak about bond we should deal with electronegativity not the number of the neutrons or the melting points
second if the two electonegativities are similar then the electrons will be shared as in covalent bonds. but if they are different one will lose the electrons for the another one
