1 2 3 4 5 and how the question ask
Answer:
For the reaction CH3COOH→CH3COO– + H+
Among the given statements which is the correct statement?
CH3COOH is a Brønsted-Lowry base.
CH3COO– is an Arrhenius base.
CH3COOH is a Brønsted-Lowry acid.
CH3COO– is a Lewis base.
Explanation:
Bronsted acid is the proton donor.
Bronsted base is the proton acceptor.
Arrhenius base is the one that releases OH- ions when dissolved in water.
Lewis base is the one that is an electron-pair donor.
In the given reaction,
CH3COOH→CH3COO– + H+
Acetic acid releases a proton.
So, it is a proton donor.
Hence, It is a Bronsted-Lowry acid.
Third option is the correct answer.
Answer:
N₃O₆
Step-by-step explanation:
Data:
EF = NO₂
MM = 138.02 g/mol
Calculations:
EF Mass = (14.01 + 32.00) u
EF Mass = 46.01 u
The molecular formula is an integral multiple of the empirical formula.
MF = (EF)ₙ
n = MF Mass/EF Mass
n = 138.02 u/46.01 u
n = 3.000 ≈3
MF = (NO₂)₃
MF = N₃O₆
