Answer:
theory
Explanation:
A theory has been tested and proven several times and oftentimes has a large amount of information, research, and evidence standing behind it.
Hope this helps! :)
True. Atoms with atomic numbers higher than 92 are not very stable and have half lives shorter than the age of the earth so they are not found naturally. Due to that, the process of transmutation must be used to get atoms with the atomic number higher than 92.
Answer:To convert the model of one constitutional isomer to another constitutional isomer one needs to exchange 2 atoms/groups on different atoms.
To convert the model of one stereoisomer to another stereoisomer one needs to exchange 2 atoms/groups bonded to the same carbon.
To convert the model of one conformational isomer to another conformational isomer one only needs to rotate about single bond(s).
Explanation:
Constitutional isomers differ from each other in position of substituents. Hence if we interchange atoms or groups on two different atoms, we get constitutional isomers.
Stereo isomers posses different orientations in space. If two atoms or groups on the same carbon atoms interchange their spatial orientation, we have a different stereoisomer other than the original structure.
Conformers arise by free rotation across single bonds. Different conformers can be created by rotating single bonds.
The sample response given in the question is right.
To find the answer, we need to know more about the distance and displacement.
<h3>How distance differ from displacement?</h3>
- Displacement is the shortest distance between the initial and final points of a body.
- It is the change in position with a fixed direction.
- Displacement is a vector quantity and can be positive, negative or zero values.
- Distance is the length of actual path of the body between initial and final positions.
- It's a scalar quantity and it can be positive or zero.
- The magnitude of displacement is less than or equal to the distance travelled.
Thus, we can conclude that the given sample response is right.

<h3>
Answer: b) 0.250 mol</h3>
============================================
Work Shown:
Using the periodic table, we see that
- 1 mole of carbon = 12 grams
- 1 mole of oxygen = 16 grams
These are approximations and these values are often found underneath the atomic symbol. For example, the atomic weight listed under carbon is roughly 12.011 grams. I'm rounding to 2 sig figs in those numbers listed above.
So 1 mole of CO2 is approximately 12+2*16 = 44 grams. The 2 is there since we have 2 oxygens attached to the carbon atom.
-------------------
Since 1 mole of CO2 is 44 grams, we can use that to convert from grams to moles.
11.0 grams of CO2 = (11.0 grams)*(1 mol/44 g) = (11.0/44) mol = 0.250 mol of CO2
In short,
11.0 grams of CO2 = 0.250 mol of CO2
This is approximate.
We don't need to use any of the information in the table.
