The components of poison ivy and poison oak that produce the characteristic itchy rash are catechols substituted with long-chain alkyl groups. If you were exposed to poison ivy, which of the treatments below would you apply to the affected area?

Explanation:

Although there are no actual solutions to the effects caused by poison ivy, there are still various different treatments that can help alleviate the symptoms. Sodium bicarbonate is a base that will increase pH. An increase in pH will cause the catechol to ionize. A charged substance will be more soluble in water. Soap helps with the solubility of the long alkyl chain. Another very helpful treatment would be to rub alcohol on the affected area, this can remove the  urushiol oil from the skin, helping to minimize discomfort

the answer is a and have a great day

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
