Answer:
C. 2.0 mL
Explanation:
This value is due to the fact that the burettes are instruments that allow accurately measure volumes of liquids, in this case it has a precision of ±0.01 mL, which indicates that this is the smallest value that the burette can measure with accuracy, which indicates that 2 mL can be measured accurately without any problem.

Answer:2 Li+CO2+H2O=LiHCO3+H2
Explanation:
Answer:
a partial negative charge
Explanation:
The oxygen on water molecules carries a partial negative charge on it. Water is made up of oxygen and hydrogen bonded via polar covalent bonds.
This bond involves the attraction between two atoms that shares their valence electrons in covalent bonding. The oxygen atom is more electronegative with more affinity for the shared electron. This suggests that it will pull the shared electrons more closer than the hydrogen atom.
This pull due to electronegativity difference leaves a partial negative charge on oxygen and a partial positive charge on hydrogen.
