Explanation:
Part A
Boiling point of HF is much higher as compared to the boiling point of HCl.
Reason:
The strongest inter molecular hydrogen bonding exist between HF molecules This is due to highly electronegative Fluorine atom.
Part B
The type of bonding present in the given compounds are:
1. Ice
The water molecules in ice are linked to each other through intermolecular hydrogen bonding due to the presence of electronegative oxygen atom that is attached to hydrogen atom.
2. Copper dioxide
In Copper dioxide, Copper and oxide ions are linked to each other via electrostatic force of attraction due to the presence of electronegative Oxygen atom and electropositive Cu atom.
Therefore, ionic bond is present in it.
3. Steel
In steel, metal and negatively charged electrons are linked to each other, thus giving rise to metallic bond between steel molecules.
4. Silicon elastomer
In silicon elastomer, Silicon atom is linked to other atom via covalent bonds due to sharing of electrons.
5. Tungsten
In the case of tungsten also, atoms are bonded to each other via metallic bond.
Mixture because your pouring something into it then stirring it i don’t know.
Answer:
mass spectrometer
Explanation:
The masses of atoms and molecules can be measured using an instrument called mass spectrometer. This instrument can be used to also measure their relative concentrations. The mass spectrometer functions using the magnetic force that is applied on a charged particle that is in motion.

I will try my best.
1. To improve how people live
2. A constraint
3. Test product safety
4. None of the above.
Sorry if any of them are wrong.
