d. the chemical is a limiting factor for the gnats.
Answers
Answer:
The correct answer is option b.
Explanation:
A limiting factor or limiting reagent is a compound of reactant which gets used up first and effects the formation of product in a chemical reaction.
Around the pond frog would be feeding on gnat, and due to their presence population of gnats were in control .But due to accidental spilling of chemical in pond resulted in death of frogs. Which were actually responsible for less population of gnats around the pond but due to dead action of chemical on them (frogs) their population in pond declined due to which increase in population of gnats was observed.
On generalizing this fact:
- Higher the population of frogs lower will be the population of gnats.
- lower the population of frogs higher will be the population of gnats.
So, from this we can conclude that frogs are the limiting factors for the gnats as more the number of frogs lessor will be number of gnats.
the frogs limit the reproduction of the gnats, and therefore with less frogs the gnat population can increase

Answer: Option (d) is the correct answer.
Explanation:
Density is defined as mass per unit volume.
Mathematically,
where d = density
m = mass
v = volume
Density is also known as degree of compactness, that is, more closely the atoms are linked more will be the mass of object or atom. Hence, more will be its density.
Thus, we can conclude that

Answer:
-1215.9J is the work done
Explanation:
It is possible to find work done in the change of volume of a gas at constant pressure using:
W = -P×ΔV
Where W is work, P is pressure and V is change in volume}
Replacing:
W = -6atm×(5L-3L)
W = -12atmL
As 1atmL = 101,325J, work done in joules is:
-12atmL ×(101.325J / atmL) = -1215.9J is the work done
The value of work done when a volume increases from 3 liters to 5 liters at 6 atm of pressure is -1215.9 Joules.
How do we calculate workdone?
Workdone on any boby or by the body will be calculated as:
W = -P×ΔV, where
W = workdone
P = applied or exerted pressure = 6 atm
ΔV = change in volume due to workdone = (5-3) L
Negative sign in the formula shows that work is done on the opposite side of the pressure or volume.
On putting all these values on the above equation, we get
W = -6atm × (5L-3L)
W = -12 atmL
We know that, 1 atmL = 101,325 J,
So, workdone in joules will be written as:
-12 atmL × (101.325J / atmL) = -1215.9 J
Hence, -1215.9 J is the workdone.
