Answer:
lowest to Highest
Carbon atom
Methane molecule (CH4)
Graphite
Diamond
Explanation:
A carbon atom would be the lowest complexity on this list, that is because it is a lone molecule with no other bonding between other atoms. The same forces interacting between the carbon atom would be the same for the others.
Next would be methane. Methane is a hydrocarbon composed of a single carbon atom bonded covalently with four hydrogens. The electrons within the hydrogen atoms repel each other causing them to be dispersed around the carbon atom to form a
tetrahedral shape. While more complex, the other two are continuous structures made from carbon atoms bonded to gather to form crystal structures.
Graphite is considered to be a crystal structure, just like a diamond. However, the biggest difference between them is their atomic and crystal frameworks. Diamonds have a rigid 3-dimensional structure whilst graphite is composed of 2d planes of graphite with carbon-carbon double bonds connecting the layers. Due to this, a diamond would be more complex then grpahite
Answer:
Of the following equilibria, only one will shift to the right in response to a decrease in volume.
On decreasing the volume the equilibrium will shift in right direction due to less number of gaseous moles on product side.
Explanation:
Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.
This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.
Decrease the volume
If the volume of the container is decreased , the pressure will increase according to Boyle's Law. Now, according to the Le-Chatlier's principle, the equilibrium will shift in the direction where decrease in pressure is taking place. So, the equilibrium will shift in the direction number of gaseous moles are less.
On decreasing the volume the equilibrium will shift in right direction due to less number of gaseous moles on product side.
On decreasing the volume the equilibrium will shift in left direction due to less number of gaseous moles on reactant side.

On decreasing the volume the equilibrium will shift in left direction due to less number of gaseous moles on reactant side.

On decreasing the volume the equilibrium will shift in no direction due to same number of gaseous moles on both sides.

On decreasing the volume the equilibrium will shift in no direction due to same number of gaseous moles on both sides.
The number of grams of radon 222 did it have 15.2 ago was 49.6 grams( answer C)
<u>calculation</u>
- calculate the number of half life it has covered from 15.2 days to 3.8 days
that is divide 15.2/ 3.8 = 4 half life
- half life is time taken for a radio activity of a specified isotope to fall to half its original mass
therefore 3.8 days ago it was 3.1 x2 = 6.2 grams
7.6 days ago it was 6.2 x2 = 12.4 grams
11.4 days ago it was 12.4 x2= 24.8 grams
15.2 days ago it was 24.8 x2=49.6 grams
