Brad and Matt are working in the lab. They noticed that when they mixed two dilute solutions together, the reaction between them

happened very slowly. Which of Matt's suggestions would BEST help to increase the rate of this reaction?

Alona [7]

Explanation:

The reaction equation will be as follows.

$Na^{+} + e^{-} \rightarrow Na(s)$

Hence, moles of Na = moles of electron used

Therefore, calculate the number of moles of sodium as follows.

No. of moles = $\frac{mass}{\text{molar mass}}$

= $\frac{4500 g}{23 g/mol}$ (as 1 kg = 1000 g)

= 195.65 mol

As, Q = $n \times F$ where F = Faraday's constant

= $195.65 mol \times 96500 C$

= $1.88 \times 10^{7}$ mol C

Relation between electrical energy and Q is as follows.

E = $Q \times V$

Hence, putting the given values into the above formula and then calculate the value of electricity as follows.

E = $Q \times V$

= $1.88 \times 10^{7} \times 5$

= $9.4 \times 10^{7} J$

As 1 J = $2.77 \times 10^{-7}$ kWh

Hence, $\frac{9.4 \times 10^{7}}{2.77 \times 10^{-7}}$ kWh

= 3.39 kWh

Thus, we can conclude that 3.39 kilowatt-hours of electricity is required in the given situation.

What is it about the structure of methyl alcohol that would result in two major peaks in its NMR spectrum?

UNO [17]

Explanation:

In case of methyl alcohol , i.e. , CH₃OH ,

counting the equivalent protons , there are three protons of the methyl group at are all equivalent , and shows the chemical shift at 3.4 - 4.0 ppm , there is the increase in the chemical shift value due to the presence of an electronegative oxygen atom .

And there is one more hydrogen atom in the alcoholic functional group , and this hydrogen will also show a chemical shift at 5.0 - 5.5 ppm .

Therefore ,

Methyl alcohol will show two signals due to methyl proton and another due to OH hydrogen .
