Answer:

Reaction mechanism has been given below

Explanation:

Propanoyl chloride contains an electrophilic carbonyl center to give nucleophilic acyl substitution reaction by removing Cl group with a strong nucleophile like methylmagnesium bromide.
Two equivalent of methyl magnesium bromide react with cabonyl center followed by protonation of negatively charged oxygen atom gives 2-methyl-2-butanol.
In the first step, nucleophilic acyl substituion occurs. In the second step, nucleophilic addition occurs. In the third step, protonation occurs.
Reaction mechanism has been shown below.

The moles of oxygen gas (O2) that is needed is 4 moles

Explanation

2H2 +O2 → 2H2O

The moles of O2 is determined using the mole ratio of H2:O2

that is from equation above H2:O2 is 2:1

If the moles of H2 is 8 moles therefore the moles of O2

= 8 moles x 1/2 = 4 moles

What is the oxidation number of HCLO4?

ki77a [65]

E.g. in H3PO4 (O, -2).
8. The sum of the oxidation states of all the atoms in a species must be equal to net charge on the species. e.g. Net Charge of HClO4 = 0, i.e. [+1(H)+7(Cl)-2<span>*4(O)] = 0.</span>

WHAT ARE SOME POSSIBLE CONSEQUENCES IF A HUMAN BODY DOES NOT MAINTAIN<br> HOMEOSTASIS

BARSIC [14]

Answer: If homeostasis is disrupted, it must be controlled or a disease/disorder may result.

Explanation: What happens if there's disruption? Your body systems work together to maintain balance. If that balance is shifted or disrupted and homeostasis is not maintained, the results may not allow normal functioning of the organism.
