Answer:
the boiling point of HF is higher than H2 and F2
Explanation:
it is because inter molecular give is present in HF because of the Hydrogen bond present. Hydrogen bond is strong and will require much energy to break ,since no hydrogen bond is in the rest H2 and F2 has a low boiling point
The answer would be 32.4m
The instrument is a Geiger counter and is used to measure radioactive level around people's bodies.
Answer: 2.186 m
Explanation:
formula for molality: (mol solute)/(kg solvent)
Na2CO3 = solute
510g Na2CO3 * ( 1 mol / 106 g) = 4.811 mol solute
ethylene glycol = solvent
2.2 * 10^3 g * ( 1 kg / 1000 g) = 2.2 kg
(4.811/2.2) = 2.186
