Hemiacetals are compounds that are derived from aldehydes and ketones while acetals are compounds with a central carbon atom with 4 bonds attached to it. It must be saturated and has a tetrahedral geometry.
Answer: One way to separate a racemic mixture is through Crystallization.
Explanation:
A separation of a racemic mixture into their component enantiomers, is well know as "resolution"
When separating a racemic mixture of tartaric acid, the easiest way to do it, is by crystiallization.
As we can see in the diagram, we introduce a pure enantiomer seed that will start the desire conglomerate, and under repetead cycles of cooling and heating, the pure conglomerate crystal will grow, thereby leaving the other enantiomer in solution.
All nuclear chemistry revolves around changing the identity of base elements.
The answer is the third statement.
Because nuclear chemistry is changing base elements' identities, the atomic number/number of protons is what is changing. While the number of electrons can change, your question is too general to know whether electrons are going to be gained, lost, or retained in the reaction.
Answer:
The answer to your question is 175 gallons
Explanation:
Data
60% antifreeze solution volume = ? = x
25% antifreeze solution volume = 25%
Final concentration 50%
Process
0.6x + 0.25(70) = 0.5(70 + x)
Simplification
0.6x + 17.5 = 35 + 0.5x
0.6x - 0.5x = 35 - 17.5
0.1x = 17.5
x = 17.5/0.1
Result
x = 175 gallons
