<span>50 quarts of 60% solution and 50 quarts of 40% solution.
You want a total of 100 quarts, so we'll use the following expressions
x = amount of 60% solution
(100 - x) = amount of 40% solution.
The total amount of alcohol will be
0.6x + 0.4(100-x)
We want the final result to be 100 quarts of 50% solution, so we express that as
0.5 * 100
Now we set them equal to each other, and solve for x
0.6x + 0.4(100-x) = 0.5 * 100
Distribute the .4
0.6x + 0.4*100 - 0.4x = 0.5 * 100
0.6x + 40 - 0.4x = 50
Subtract 40 from both sides and combine the x terms
0.2x = 10
Divide both sides by 0.2
x = 50
Now we know we need 50 quarts of the 60% solution. And we need (100 - 50) = 50 quarts of the 40% solution as well.</span>
Answer:
Neon molecule does not exist.
Explanation:
Neon is denoted by Ne which is noble gas. According to the "Molecular Orbital Theory", only those molecules exist that have a positive bond order and molecules with no bond or negative bond order cannot exist.
Well the group fluorine is in is known as Halogens. Halogens all have seven valence electrons in their outer shell. They exist as diatomic molecules. Furthermore they readily combine with metals to form salts
Well the solvent is the liquid in a solution so your answer would be Solute, D. That is the one that would represent the sugar crystals being evenly mixed into a solution.
