Individual organisms live together in an ecosystem and depend on one another. Other organisms have to get their food by eating other organisms.
There are also cases when a negative change in entropy can lead to a spontaneous reaction. According to this equation, if the free energy, G, of the system is negative, then the reaction is spontaneous.
Answer:
A. London dispersion
Explanation:
London dispersion force is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles.
Answer:
Thus, the pollutant concentration in lake will be reduced to 0.2% after 6.931471 days
Explanation:
From the information given:
A(t) = amount of pollutant for time (t)
A 4 billion cubic ft is the same as 4000 million cubic ft:
∴
The Initial amount of pollutant is
However;
the pollutant rate (input) = 400 × 0 = 0
the pollutant rate (output) =
The net rate =
A(0) = 16
A(t) = 8
Answer:Sol. P base 1 = 10 kpa = 10 × 10^3 pa. P base 2 = 50 × 10^3 pa. v base 1 = 200 cc. v base 2 = 50 cc (i) Work done on the gas = ½ (10+50) ...
Explanation:
