m/1,609.344=mi (meters divided by 1,609.344 equals miles)
The answer is actually A, 1s 2s 2p 3s 3p 4s 3d 4p.
B. The atomic number. This is because the atomic number is the same as the number of protons an element has, and the number of protons defines an element.
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>
