Why electrons don't spiral into atomic nuclei is best explained by their?

1 answer:

7 0

Electrons are negatively charged particles while protons that are found in the nucleus are positively charged. In the natural scheme of things, positive and negative charge produces an attractive force that pulls one particle towards the other. However, based on Rutherford's model of an atom, which is the planetary model that conclusively suggests that electrons revolve around the nucleus, such attraction between the two opposing particles creates an electromagnetic force that enables electrons to move around the positive nucleus thus preventing the electrons from spiraling towards it.

How might the yield of 1-bromobutane be affected if water was not added, and what product(s) would be favored?

jek_recluse [69]

Due to the inability of the reaction to take place, the yield of 1-Bromobutane would drop.

Since 1-Butanol won't react with the additional sodium bromide, bromination won't happen.

If water had been supplied, the equilibrium would have shifted extremely far to the left, preventing the reactants from interacting with the acid and favoring the yield of 1-bromobutane instead.

<h3>What is Bromination?</h3>

When a substance undergoes bromination, bromine is added to the compound as a result of the chemical reaction.

After bromination, the result will have different properties from the initial reactant.
For example, an alkene is brominated by electrophilic addition of $Br_{2}$ .
Benzene ring bromination by electrophilic aromatic substitution.

Indicate which of the following criteria are important for the selection of a buffer to use in an in vitro biochemical reaction.

JulsSmile [24]

Answer:

The correct answer is: d. The pKa of the chosen buffer should be close to the optimal pH for the biochemical reaction.

Explanation:

The buffer resist or maintain the change in pH in case of Acid or basic addition to the solution. The buffer capacity should be within one or two pH units when compared to the optimal pH.

Thus it is important to select a buffer with pKa close to the optimum pH of the reaction because the ability for the buffer to maintain the pH is is great at the pH close to pKa.
