An ion is a charged particle that is formed when an atom gains electrons or an atom loses electrons.

First you need to know the definition of ion. An ion is a molecule or atom that has a positive or negative electrical charge. That is, an ion is an atom whose electric charge is not neutral. This charged particle can be positive or negative.

Ionization is the chemical or physical process by which ions are produced. In this process, negatively charged ions are produced by gaining electrons and are known as anions. The positively charged are produced by the loss of electrons and are known as cations.

In summary, an ion is a charged particle that is formed when an atom gains electrons or an atom loses electrons, and they are known as cations and anions respectively. The correct answer is both A and B.

If a substance has a mass of 12.50 g and takes up 3.4 mL of space, what is the density?

miskamm [114]

Answer:

The answer is

Explanation:

The density of a substance can be found by using the formula

<h3> $density = \frac{mass}{volume}$ </h3>

From the question

mass of substance = 12.50 g

volume = 3.4 mL

The density of the substance is

$density = \frac{12.50}{3.4} \\ = 3.676470588...$

We have the final answer as

Hope this helps you

Consider the reaction: HCN (aq) + H2O (l) ⇄ CN- (aq) + H3O + (aq) Which of the following statements will decrease the amount of

alekssr [168]

Answer: Option (b) is the correct answer.

Explanation:

The given chemical reaction shows that hydrogen cyanide acid has been added to water which results in the formation of hydronium ion and cyanide ion.

Also, when we add a base like sodium hydroxide (NaOH) to HCN then it will help in accepting a proton ( $H^{+}$ ) from hydrogen cyanide. As a result, formation of $CN^{-}$ anion will be rapid and easy.

This will make the system not to do any extra work. So, amount of work done by system will decrease.

Thus, we can conclude that out of the given options, add solid NaOH to the reaction (assume no volume change) will decrease the amount of work the system could perform.
