A. Atomic radius increases
Answer:
A chemical structure of a molecule includes the arrangement of atoms and the chemical bonds that hold the atoms together. The 2-HEPTANONE molecule contains a total of 21 bond(s) There are 7 non-H bond(s), 1 multiple bond(s), 4 rotatable bond(s), 1 double bond(s) and 1 ketone(s) (aliphatic).
Answer:
The correct option is <em>replication.</em>
Explanation:
<em>In the English language, replication simply means to practice something which has already been done or to copy something.</em>
In an experimental class, the demonstrator has to perform an experiment before the students so that the students get a better understanding about what needs to be done. Also, the demonstrator should guide the students with the precautions which need to be taken for that experiment.
The students then copy the experiments as were shown by the demonstrator. In this way, they can perform the experiment in a better way with not many errors. This shows an act of replication.
Explanation:
A mole is the amount of matter or substance that contains the Avogadro's number of particles.
1 mole of a substance = 6.02 x 10²³ atoms
Now solving:
a:
1.2 x 10² atoms ;
Number of moles = = 2.0 x 10⁻²¹moles
b:
3.87 x 10²¹ molecule:
Number of moles = = 6.4 x 10⁻³moles
c. 4.81 x 10¹⁴ molecules:
Number of moles = = 8.0 x 10⁻¹⁰moles
Number of molecules = number of atoms = formula units
