How many hydrogen atoms are in each molecule of trisilylamine?
lord [1]

Answer:

  • <u>9</u>

Explanation:

The amine functional group is obtained by subsititution of one or more hydrogen atoms in the ammonia compound.

Ammonia is NH₃.

Then,

  • by substituting one hydrogen you obtain R - NH₂.

  • by substituting two hydrogens you obtain R' - NH - R''

  • by subsituting the three hydrogens you obtain:

                        R'''

                         |

                 R' -  N - R''

In this case, the three subsitutuents are silyl groups. The silyl group is derived form silane and is SiH₃. So, the tcompound <em>trisilylamine</em> is:

                    SiH₃

                      |

          SiH₃ -  N - SiH₃

Thus, you can count 3 hydrogen atoms for every silylgroup for a total of <u><em>9 hydrogen atoms in each molecule of trisilylamine.</em></u>

What is the final electron acceptor in cellular respiration?
Artemon [7]
<span>The potential of NADH and FADH2 is converted to more ATPthrough an electron transport chain with oxygen as the "terminal electron acceptor". Most of the ATP produced by aerobic cellular respiration is made by oxidative phosphorylation.

Hope this helps. :)

How do Hydrogen-1, Hydrogen-2, and Hydrogen-3 differ from each other?
Anna71 [15]

Answer:

different from the number of their neutrons

Explanation:

They each have one single proton (Z = 1), but differ in the number of their neutrons. Hydrogen has no neutron, deuterium has one, and tritium has two neutrons. ... Their nuclear symbols are therefore 1H, 2H, and 3H. The atoms of these isotopes have one electron to balance the charge of the one proton.
