Most covalent compounds have relatively low melting points and boiling points. Covalent compounds usually have lower enthalpies of fusion and vaporization than ionic compounds. Covalent compounds tend to be more flammable than ionic compounds. When dissolved in water, they don't conduct electricity.

2 There is about 1000ml in a liter. 1 multiply 1050 by 0.15.
Answer:
Explanation: Electrolysis uses DC electricity as a energy source.
E°cell =+1.34V
F= 96485C mol-1
3Cu(s) →3CU2+(aq) +6e-E°ck= -0.34V
2MnO4-(aq) +8H+(aq)+6e→2MnO2(s)+4H2O(l)/3CU(s) + 2MnO4-(aq)+8H+(aq)→3CU 2+((aq)+ 2MnO2(s)+4H2O (l)
E°red= +1.68V/E°cell=+1.34V
ΔG° = -nFE°cell = -6×96485×1.34 = -775.7kJ/mol
Vibrate
Explanation:
Through conduction, energy is transferred as particles vibrates into one another.
Conduction is one of the modes of heat transfer. Others are convection and radiation.
- Thermal conduction occurs by the vibrations of molecules of solids.
- When heat is added to body, gain kinetic energy.
- This energy causes the molecules fixed to begin to vibrate around their fixed point.
- When they break free, they start colliding with one another and other molecules with lower energy away from the heat source.
