1-requires carbon
2-requires carbon for photosynthesis to occur
3-carbon is an output of cellular resp.
Hope this helps:)
Water is polar meaning that it has prominent areas of negative and positive charge. Among water molecules there is a weak force called hydrogen bonding which causes the molecules to "stick" to one another. This sticking to itself is called cohesion, and it causes water to ball up into droplets. This same force also causes water to stick to other kinds of molecules. This is called adhesion, and it is what causes water to ride up on the side of a water container slightly.
Answer:
904.8 kg / m3
Explanation:
19.0 kg/0.021 m^3 = 904.761905 kg / m3
That answer is either 3 or 4, but I truly forgot which of the two.
Explanation:
Since, it is shown that the reaction has been reversed. Therefore, value of
will become
.
Hence, new 
= 
= 20
Also, the number of moles of each reactant has been halved. So,
for the reaction
will also get halved.
Therefore,
=
= 
= 4.47
As the value of
is given as +39.0 kJ. So, it means that the reaction is endothermic in nature. So, energy of reactants will be more than the products. Hence, according to Le Chatelier's principle reaction will move in the forward direction.
As a result,
will also increase with increase in temperature.
