Answer:
[CO2] > [N2] > [He]
Explanation:
The relative concentration of CO2, N2 and He depends on the solubility of each gas in water. The more soluble in water a gas is, the greater its concentration in aqueous solution.
Among the gases listed, CO2 is most soluble in water hence it is expected to have the greatest concentration in solution followed by N2. Helium gas is insoluble in water hence it has the least concentration in the aqueous solution.
the san andreas fault is the correct answer
Answer:using fertilizers on crops
Explanation:carbon dioxide in the atmosphere is absorbed by plants.plants use it to produce their food. An increase in atmospheric carbon dioxide is caused by cutting down of forest and burning of fossil fuels.this increase in the emissions of carbon dioxide is harmful to the earth. Gases like chlorofluorocarbons ,carbon dioxide etc can cause global warming. This gases causes the heat not to escape from the earth atmosphere,just as it is in a green house. When this happens heat is trapped in the earth it causes global warming. These gases are released by burning of fuel, CFCs from old refrigerators and air conditioner.
Increase in the heat in the earth can cause melting of ice in the polar region.this can lead to a raise in sea level and flooding.
Answer:
The absolute pressure inside the ball is 1.25atm.
Explanation:
Given-
Volume, V = 5..27L
Temperature, T = 27°C
Gauge Pressure, Pg = 0.25 atm
Atmospheric pressure, Patm = 1 atm
Absolute pressure, Pabs = ?
We know,
Therefore, absolute pressure inside the ball is 1.25atm.
Answer:
Coefficient in front of the 
in the balanced equation - 4
Explanation:
The unbalanced reaction is shown below as:-
On the left hand side,
There are 1 nitrogen atom and 3 hydrogen atoms and 3 oxygen atoms
On the right hand side,
There are 1 nitrogen atom and 2 hydrogen atoms and 2 oxygen atoms
Thus,
Right side, 
must be multiplied by 6 and by 4
Left side, 
is multiplied by 5 and 
by 4 so to balance the whole reaction.
Thus, the balanced reaction is:-
<u>Coefficient in front of the in the balanced equation - 4</u>
