Answer:

Overall, the electric charge of the compound ${\rm NaOH}$ is $0$ .

Explanation:

Sodium hydroxide ${\rm NaOH}$ is an ionic compound. This compound is made up of a large number of sodium ions ${\rm Na^{+}}$ and hydroxide ions ${\rm OH^{-}}$ .

As the superscripts suggest, each sodium ion ${\rm Na^{+}}$ carries a charge of $(+1)$ while each hydroxide ion ${\rm OH^{-}}$ carries a charge of $(-1)$ .

The two types of ions are paired up at a one-to-one ratio within ${\rm NaOH}$ . Charges on these ions would balance one another, such that the overall electric charge on the compound ${\rm NaOH}\!$ would be $0$ .

Which of the following are functions of the ears?

Advocard [28]

The functions of the ears are:

I. Hearing by collecting and processing sound waves

II. Keeping our balance when we turn or bend over; option A

<h3>What is the function of the ear?</h3>

The ear is one of the five sense organs in the body.

The sense organs are the organs which receive external stimulus and send it to the brain for processing and response.

The other sense organs are:

the eye
the nose
the skin
the tongue

The functions of the ear are for hearing and for balance.

In conclusion, the sense organs function to receive stimulus and send them to the brain.

g Select the correct statements. I. Reduction is the loss of electrons, and oxidation is the gain of electrons II. Reduction is

Karolina [17]

<u>Answer:</u> The correct answer is Option D.

<u>Explanation:</u>

Reduction reaction is defined as the reaction in which a substance gains electrons. Here, the oxidation state of the substance decreases.

$X^{n+}+ne^-\rightarrow X$

Oxidizing agents are the agents that helps in the oxidation of other substance and itself gets reduced. These agents undergoes reduction reactions.

Oxidation reaction is defined as the reaction in which a substance looses its electrons. Here, oxidation state of the substance increases.

$X\rightarrow X^{n+}+ne^-$

Reducing agents are the agents that helps in the reduction of the other substance and itself gets oxidized. These agents undergoes reduction reactions.

Oxidation state is the number which is given to an atom when it looses or gains electron. It is written as a superscript. In a compound, the total charge is equal to the sum of the charges of all atoms in that compound. <u>For Example:</u> In $MnO_4^-$ , manganese has +7 oxidation number and oxygen has -2.
