Answer:
Physical Properties of Water (H2O):
It is Colorless Liquid.
It is Tasteless.

It freezes at (0) zero, degree Celsius.
It boils at 100 degrees Celsius.
Chemical Properties:
It is the BEST solvent of all solvents.
When decomposes, it gives two atoms of Hydrogen (H2) and one atom of Oxygen (O).
It is an excellent diluent for all acids.

you can also use the key, which is where certain places have a specific sign to that area, that probably didnt make sense...
Answer: C. Ionic
Explanation: The transfer of one or more electrons from one atom to another means that certain atoms are "amplified" by negative charge, since the electrons are negative, while the other atoms from which the electrons leave become positive. This means that such atoms become negative and positive ions, causing each other to attract opposite charged ions, creating an ionic bond.
