Answer:. an ionic compound
Explanation:
If it conducts electricity when molten, then it is an ionic compound. No covalent compound conducts electricity in molten state because their crystal lattice is not composed of ions. There are ionic solids which conduct electricity when molten but are insoluble in water such as alumina Al2O3. The solid is soluble in strong acid solutions.
Answer:
Hydrogen bonding is caused by the tendency of some atoms in molecules to attract electrons more than their accompanying atom. This gives the molecule a permanent dipole moment , it makes it polar, so it acts like a magnet and attracts the opposite end of other polar molecules.
Explanation:
Answer:
Warm water has more energy than cold water. The more energy the more the water molecules move around pushing the food coloring. Think gas—liquid is evaporated because of heat and the molecules move more than in a liquid state.
Well to separate talc from water you can use the method of Filtration
and if you don't know what Filtration is go to a dictionary for chemistry/Science
or if you you have one then you could use it .
[hope this helps]
I love this game and love this app so
