Answer: mole
A formula unit represents the simplest ratio of elements in a mole of an ionic compound.
Explanation:
The formula unit, also known as the empirical formula, gives the simplest whole number ratio of the components of the elements in a mole of an ionic compound.
Thus, the formula unit and the molecular formula of a compound can be the same.
For example: Glucose with C6H12O6 will have a formula unit of CH2O. Thus, the simplest ratio of carbon, hydrogen and oxygen in glucose is 1:2:1
Answer:
The attached figure shows the structure of dimethyl terephthalate.
Explanation:
Dimethyl terephthalate is a compound whose formula is C6H4 (COOCH3) 2. It is a diester produced from terephthalic acid and methanol. It is characterized by being a white solid. Another method for the preparation is from p-xylene and methanol, which is characterized by having an oxidation and an esterification.
Animals with larger weights compensate for the large force they exert on the ground, by having a large footprint area in order to reduce the pressure of their feet on the ground.
<h3>Why do animals with large weight have large feet?</h3>
Large animals such as elephants, lions, hippopotamus, etc, usually have a large foot print area compared to smaller animals.
This larger footprint area helps to support their weight.
The weight of these animals exerts a force as well as pressure on the ground.
Pressure, force and area are related by the equation below:
The larger the area, the smaller the pressure.
In order to compensate for the large force they exert on the ground, larger animals possess a large footprint area in order to reduce the pressure of their feet on the ground.
