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

It can be any row
Explanation:
An element with a valence electrons of 3 can be in any row on the periodic table.
The rows are the horizontal arrangement of elements on the periodic table.
Elements on the same row have the same energy level.
- The periodic table rows are called periods.
- It is only in the groups that we can find such element.
- Group 3 elements have 3 valence electrons.
- Since this group cuts through all the rows, therefore, elements with 3 valence electrons can be found in any row.

The reactants has 2 NO2 and the product has 3. So we need to make sure we have 6 on each side.
Al + 3Fe(NO2)2 -> Fe + 2Al(NO2)3
This leaves us with us just to balance the Fe And Al
2Al + 3Fe(NO2)2 -> 3Fe + 2Al(NO2)3
