The atomic number of cobalt, CO is 27. Since, the cobalt that you asked is in ion. The number of electrons should be 27-3 --> *24* Reasons being that cobalt has donated/given away 3 electrons.
Answer:
0.071 mole
Explanation:
As discovered from Avogadro's hypothesis, 1 mole of any substance contains 6.02x10^23 molecules.
This simply means that 1 mole of H3PO4 also contains 6.02x10^23 molecules.
If 1 mole H3PO4 contains 6.02x10^23 molecules,
Then, xmol of H3PO4 will contain 4.3x10^22 molecules i.e
Xmol of H3PO4 = 4.3x10^22/6.02x10^23 = 0.071 mole
From the calculations made above, 4.3x10^22 molecules of H3PO4 have 0.071 mole of H3PO4

Answer: the correct options are A, B and D
Explanation: the implications of histone acetylation involves that the acetyl groups (-COCH3) are attached to positively charged lysines in histone tails, the process loosens chromatin structure, and
It promotes the initiation of transcription.
