<u><em>The variable quantities are expressed by the ideal gas law equation are; </em></u>
<u><em>pressure, volume, temperature, number of moles</em></u>
<u><em /></u>
This question is simply based on defining the ideal gas law.
- Now, A gas is considered to ideal if its particles are so far from each other in such a manner that they don't exhibit any forces of attraction between themselves. Now, in real life this is not possible but under high temperatures and pressure, we can have something close to it and that's why ideal gas laws are very important.
- This law states that states that the pressure, temperature, number of moles and volume of a gas are related to each other by the formula;
PV = nRT
Where;
P is pressure
V is volume
n is number of moles
T is temperature
R is ideal gas constant (This is fixed and not variable)
The variable quantities are expressed by the ideal gas law equation are;
<em>pressure, volume, temperature, number of moles</em>

Answer: New concentration of 
is 0.23 M.
Explanation:
The given data is as follows.
Moles of = 0.06 mol
Moles of 
= 0.08 mol
Therefore, moles of 
added are as follows.
Moles of = 
= 0.003125 mol
Now, new moles of = 0.06 + 0.003125
= 0.063125
Therefore, new concentration of will be calculated as follows.
Concentration = 
= 0.23 M
Thus, we can conclude that new concentration of is 0.23 M.
People can reduce their exposure to BPA by washing out plastic cups, buying BPA free plastics. BPA should be kept out because it can cause a chemical interference in the human body
The molecular compound in the given statement is CH₆N₂.
<h3>What defines a molecular compound?</h3>
Chemical compositions of molecules that make up molecular compounds reflect the number of elements that are really bound together within the molecule. Due to the sides and angles of a atoms' links to one another, the complex has a certain structure.
<h3>Briefing:</h3>
Consider 140.22 g/mol of compound
Carbon = 140.22 * 51.38/100
Carbon = 72 gm = 1 mol
Hydrogen = 140.22 * 8.64/100
Hydrogen = 12 gm = 6 mol
Nitrogen = 140.22 * 39.97/100
Nitrogen = 56 gm = 2 mol
The molecular compound is CH₆N₂.

The plants are the primary source of food in a food chain or a food web. The animals which feed on plants will be termed as herbivores or primary consumers like the grasshopper. The organisms feeding on primary consumers will be the secondary consumers like mice. The snake is considered to be a tertiary consumer.
If any one of the organisms were to be removed let’s say the plant, all the other consumers would most likely die since their food supply is no longer available for them to eat. The population of other consumers could fall but could also stay somewhat the same if they eat any other food.
