It’s the 3d one
Good luckkkkkkkk
12, electrons dont have mass. only protons and neutrons do
V1 = 445ml V2 = 499ml
T1 = 274 K T2 = ?
By Charles Law,
V1/T1 = V2/T2
445/274 = 499/T2
By solving we get,
T2 = 307.25 K
Answer:
The answer is steam of fossil fuels
Answer:
: conjugate acid of 
: conjugate base of 
: conjugate base of 
: conjugate acid of 
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.

Here in forward reaction
is accepting a proton, thus it is considered as a base and after accepting a proton, it forms
which is a conjugate acid.
And
is losing a proton, thus it is considered as an acid and after loosing a proton, it forms
which is a conjugate base.
Similarly in the backward reaction,
is loosing a proton, thus it is considered as a acid and after loosing a proton, it forms
which is a conjugate base.
And
is accepting a proton, thus it is considered as a base and after accepting a proton, it forms
which is a conjugate acid.
