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
Answer:
See below
Explanation:
The common formula of the same alkene series is CnH2n, where n is the quantity of atoms of carbon. Owing to the hydrocarbons of alkenes with at least one double carbon relation, the alkene-like sequence starts with ethen C2H4.

Explanation:
The volumetric pipet is designed for a specific volume of solution. In this case, a 10 mL of volumetric pipet is required to take exactly 10 mL of the solution 1.00 M and add into a volumetric flask of 100 mL. Then water or solvent(s) can be added to reach the ring of the volumetric flask. This volumetric flask is also a laboratory equipment for precis dilutions beside the volumetric pipet
