According to Bronsted-Lowry reaction- an acid is any substance that donates a proton (H+ ion) to another substance hence these two substance are acid aspirin (acetylsalicyclic acid) and hydrochloric acid (HCl). And there are two pairs - an acid with a corresponding conjugate base and a base with a corresponding conjugate acid. These pairs are called conjugate acid-base pairs.
Answer:
B - The energy of reactants is conserved.
D - the nuclei of atoms changes completely ( if that's the option)
Answer:
C8H8O2
Explanation:
The molecular formula of a compound is simply a multiple of the empirical formula as shown below:
Molecular formula => [C4H4O]n
From the question given, we were told that molar mass of the compound is 136g/mol. This implies that:
[C4H4O]n = 136
Now, let us find the value of n in order to obtain the desired result. This is illustrated below:
[C4H4O]n = 136
[(12x4) + (4x1) + 16]n = 136
[48 + 4 + 16]n = 136
68n = 136
Divide both side by the coefficient of n i.e 68
n = 136/68
n = 2
Therefore the molecular formula is
=> [C4H4O]n
=> [C4H4O]2
=> C8H8O2
The reduced forms of the electron carries NAD+ / NADH and FADH / FADH2 have high potential energy.
- NAD& FAD used to donate electrons as a reducing agent, they receive electrons from other molecules and then became reduced.
-FAD is called flow in adenine dinucleotide, it is a redox cofactor and it is in many important enzymatic reactions in metabolism.
