Answer: The pair that consists of a base and its conjugate acid in that order.
Explanation:
According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.



is gaining a proton, thus it is considered as a brønsted-lowry base and after gaining a proton, it forms
which is a conjugate acid.

Answer:
Physical Property
Explanation:
Magnetism is temporary untill you seperate the objects. There is no chemical change involved before, after, or during.
Answer:
A. 1.63g/dm^3 (3 s.f.)
B. 0.833g/dm^3 (3 s.f.)
C. 1.92g/dm^3 (3 s.f.)
Explanation:
Please see attached picture for full solution.
λ=Wavelength = .129 m = 0.129 m
E = energy = ?
h =Planck constant = 6.63 × 10^-34 J.s
f = frequency of photo/ electromagnetic radiation = c/λ
c = Speed of light in a vacuum = 3 × 10^8 m/s
