Answer:
Whales facilitate carbon absorption in two ways. On the one hand, their movements — especially when diving — tend to push nutrients from the bottom of the ocean to the surface, where they feed the phytoplankton and other marine flora that suck in carbon, as well as fish and other smaller animals.
Answer:
The resonance structure for the cyclopentadienyl anion is shown in the drawing below.
Explanation:
The resonance representation of the cyclopentadienyl anion shows that it is a stable ion. On the other hand it is important to note that it has 6 π electrons and is aromatic.
<span>FIXATION.In the nitrogen cycle, nitrogen is converted into many chemical forms through biological and physical processes like nitrogen fixation, ammonification, nitrification and denitrification.During ammonification, ammonium ions are released after decomposition of plants.During nitrogen fixation, nitrogen gas is changed to nitrates by nitrogen fixing bacteria in the soil.These are used by vegetation.</span>
Answer:
x=34
y=20
Explanation:
let the first number be 'x'
let the second number be 'y'
Equation 1:-
x + y = 54
Equation 2:-
x = y + 14 (Since one exceeds the other by 14)
Substituting Equation 2 in Equation 1:-
(y + 14) + y = 54
=> y + 14 + y = 54
=> 2y + 14 = 54
=> 2y = 54 - 14
=> 2y = 40
=> y = 40/2
=> y = 20
Now in Equation 1:-
x + y = 54
Substituting y=20,
x + 20 = 54
x = 54 - 20
x = 34
Answer:
The final volume of the sample of gas 
= 0.000151 
Explanation:
Initial volume 
= 200 ml = 0.0002
Initial temperature 
= 296 K
Initial pressure 
= 101.3 K pa
Final temperature 
= 336 K
Final pressure 
= K pa
Relation between P , V & T is given by
Put all the values in the above equation we get
= 0.000151
This is the final volume of the sample of gas.
