In a reaction of an acid with a base, the pH changes to a value that is closer to what?

The pH changes to a value closer to 7, which is considered neutral.

This, however, only applies to all reactions between strong acids and strong bases. If the reaction either involves a weak acid and/or a weak base, the computation of the final pH may slightly be more complicated.

Which scenario best exemplifies the way a signal is passed down an axon coated with myelin sheath?
goblinko [34]

Runners sprinting short distances in a relay race and handing off a baton scenario best exemplify the way a signal is passed down an axon coated with a myelin sheath.

Axons are long extensions of neurons (or nerve cells) involved in the transmission of nerve impulses away from the cell body. Each nerve cell has an axon that is over a foot long. A nerve cell communicates with another nerve cell by transmitting signals from the branches at the ends of the axon.

Each neuron in the brain has long cables that meander from the body of the cell. These cables, several times thinner than human hair, are called axons and are where electrical impulses leave neurons and are received by other neurons.

Complete the equation to show how hydrofluoric acid, HF, acts as a Brønsted-Lowry acid in water. Balanced equation:
shepuryov [24]

Answer : The balanced equation is,

HF+H_2O\rightleftharpoons H_3O^++F^-

Explanation :

According to the Bronsted Lowry concept, Bronsted Lowry-acid is a substance that donates one or more hydrogen ion in a reaction and Bronsted Lowry-base is a substance that accepts one or more hydrogen ion in a reaction.

The balanced chemical reaction will be,

HF+H_2O\rightleftharpoons H_3O^++F^-

In this reaction, hydrofluoric acid is act as a Bronsted Lowry-acid because it donate one hydrogen ion to H_2O and H_3O^+ is act as a Bronsted Lowry-base because it accept one hydrogen ion from HF.

Is a 3.3% solution dilute or concentrated?<br><br><br><br> Dilute<br><br><br><br> Concentrated
Arisa [49]

Answer:

Dilute

Explanation:

A concentrated solutions is a one which has relatively large amount of dissolved solute in the solution whereas a dilute solution is a one which has relatively lower concentration of dissolved solute.

In the given solution there is only 3.3% of solute. So, we can say that the given solution is a dilute solution. However, these terms are relative.
