Answer:
1) intra molecular forces
2) within
3) inter molecular
4) between
Explanation:
In image below black lines indicate the <em>intra molecular forces</em> that exist <em>within</em> molecules and the red dotted lines indicate the<em> inter molecular </em>forces that exist <em>between </em>the molecules.
1) intra molecular forces
2) within
3) inter molecular
4) between
Inter molecular forces:
Inter molecular forces exist between the molecules.
Intramolecular forces:
Intramolecular forces exist between the bonded atoms with in same molecule.
Answer:
MM/n will be less than the theoretical value
Explanation:
Provided that
The plating efficiency is proportional to the element weight
i.e.
That represents
So,
MM by N value is
= 65.39 g /mol ÷ 2
= 32.70 g/mol
Also, the experimental plating value is 0.55 that represents that it is much lesser than the normal value
So it would be concluded that the MM by N would be lower than the theoretical value
Answer:
68,2%
Explanation:
Supposing the initial salt concentration of lake Parsons is the same of non-isolated lakes, 6,67L, and the change of salt concentration in isolated lake is just for water evaporation it is possible to write:
6,67gL⁻¹×X = 21gL⁻¹×Y
<em>-Where X is the initial water and Y is the water that remains in the isolated lake-</em>
Thus:
6,67X = 21Y
0,318 = Y/X
0,318 is the ratio of water that remains between total water. To obtain the ratio of evaporated water:
1-0,318 = 0,682
In percentage: <em>68,2%</em>

solution:
You need to find the frequency, and they have already given you the wavelength. And since you already know the speed of light, you can use formula (2) to answer this problem. Remember to convert the nano meters to meters because the speed of light is in meters.
