A person who chooses to take drugs has an increased risk of accidents from driving, hence option A is correct.

What is drug abuse?

Overuse of alcohol, painkillers, or illicit narcotics. It could cause injury to one's body, relationships, or emotions. Drug addiction is a sickness that drives people to consume substances compulsively in spite of negative effects.

Abuse of drugs can lead to seizures, strokes, brain damage, lung illness, issues with memory, concentration, and decision-making, as well as rises in body temperature.

Additional signs and symptoms include a rapid pulse, dilated pupils, raised blood pressure, nausea or vomiting, and dilated pupils, in additional behavioral changes including agitation and poor judgment.

Therefore, increased risk of an accident while driving under the influence, hence option A is correct.

Describe the effect of increased carbon dioxide concentration on blood pH​

Answers

Answer:

As it combines with water, it forms carbonic acid, making the blood acidic. So CO2 in the bloodstream lowers the blood pH. When CO2 levels become excessive, a condition known as acidosis occurs. This is defined as the pH of the blood becoming less than 7.35

The increase in the carbon dioxide concentration on blood pH leads to the condition known as Acidosis.

What is the normal blood pH?

The level of normal blood pH in humans significantly ranges from 7.35 to 7.45 on a pH scale. It is considered neutral but experimentally it is slightly basic in nature.

As the concentration of carbon dioxide in the blood increases, the carbon dioxide in the presence of water forms carbonic acid which lowers the blood pH from 7.35.

This reduction in blood pH is known as acidosis. This is caused by the overproduction of acid within the body due to excessive concentration of carbon dioxide in the blood's pH. Acidosis leads to feeling fatigued, lethargic, muscle aches, etc.

Therefore, the concentration of carbon dioxide on blood pH negatively harms the health of an individual.

Which two elements in the list would bond together based on their ionic charges?

A. calcium and potassium
B. potassium and neon
C. potassium and iodine
D. calcium and neon​

Answers

Answer:

It's C. Potassium and iodine

The two elements in the list that would bond together on their ionic charges is potassium and iodine. The correct option is C.

What is ionic bond?

Ionic bond, also known as electrovalent bond, is a type of linkage formed in a chemical substance by the electrostatic attraction of ions with opposite charges.

When the valence (topmost layer) electrons of one atom are indefinitely transmitted to another, a bond is formed.

The complete transmission of valence electron(s) among both atoms is referred to as ionic bonding.

It is a chemical bond that produces two opposing ions. The metal loses electrons in ionic bonds to become a positively charged cation, meanwhile the nonmetal chooses to accept those electrons to become a negatively charged anion.

Ionic bonds are formed by potassium iodide (KI). Iodine and potassium have very divergent electronegativities.

Since ionic bonds form between atoms with a large difference in electronegativity, the two atoms would form an ionic bond.

Thus, the correct option is C.
