Answer: They are all basically the same, but the number of neutrons could vary.

Explanation: The atoms of an element are basically alike. However, atoms of the same element can have different numbers of neutrons and electrons. The number of protons is always the same for atoms of the same element.

Answer: Option (A) is the correct answer.

Explanation:

An element is defined as a substance that contains atoms of same type.

As copper wire is a substance that is made up of only atoms of copper. And, all these atoms of copper will be the same. Hence, it is an element.

This means that all the atoms of copper will have same number of protons, neutrons and electrons.

Thus, we can conclude that the statement they are all exactly the same best describes the copper atoms.

PH of 0,035M HCl? How to count if your calculator hasn't got -lg?
IrinaK [193]

<u>Given information:</u>

Concentration of HCl = 0.035 M

<u>To determine:</u>

pH of the solution

<u>Explanation:</u>

Hydrochloric acid, HCl is a strong acid. It will completely dissociate to give H+ and Cl- ions

HCl → H+ + Cl-

Hence the concentration of H+ = Cl- = 0.035M

Now, pH measures the strength of H+ ions in a given solution. It is expressed as:

pH = -log[H+]

pH (HCl) = -log(0.035) = 1.46

Ans: pH of 0.035M HCl is 1.46
