Answer:
CH3COO-
Explanation:
The conjugate base if a weak acid is a strong base, and the conjugate base of a strong acid is a weak base.
Acetic acid is a weak acid, so its conjugate base (CH3COO-) is a strong base.
Nitric, sulfuric, and hydrochloric acids are all strong acid. Their conjugate bases (NO3-, SO4^2-, and Cl- are all weak bases.
C cuz it just doesn’t make sense
Atomic mass is equal to the total number of electrons neutrons and protons
CBr4 is a symmetric tetrahedral molecule so it will be non-polar.
