Richard Bader is a scientist from McMaster University who developed a way of dividing molecules into atoms. He uses zero flux surfaces to divide atoms. (A zero flux surface is a 2-D surface on which the charge density is a minimum perpendicular to the surface). Usually in molecular systems, the charge density reaches a minimum between atoms and this is a natural place to separate atoms from each other. more info- http://theory.cm.utexas.edu/bader/
What else can I help you with?
To separate two liquids by distillation what must be different?
The boiling points of the two liquids must be different in order to effectively separate them by distillation. This allows one liquid to vaporize at a lower temperature and be collected as a separate distillate from the other liquid.
What properties must a compound have in order to be steam distillable?
For a compound to be steam distillable, it must have a higher vapor pressure than water at the temperature of the steam distillation process. Additionally, the compound should be stable under the conditions of steam distillation, meaning it does not decompose or react with water vapor. Lastly, the compound should have limited solubility in water to allow for efficient separation from the distillate.
Why must two strands of parental DNA separate?
in order to replicate to create more DNA. this is required in order to make more cells
Is Ferrous Sulfate an inorganic compound?
Yes. Ferrous sulfate, FeSO4, contains only iron, sulfur, and oxygen. In order to be considered organic, a compound must contain carbon.
What is required for a compound to conduct a charge?
This compound must be dissociated.
What event must take place to separate a compound into separate elements?
A chemical reaction must occur to separate a compound into its separate elements. This may involve breaking the bonds holding the elements together within the compound, typically through the addition of energy or the introduction of another reactant.
What must be added in order for the petroleum to separate into its fraction?
Energy, in the form of heat, must.
What must be broken down in order for DNA to separate?
Hydrogen Bonds.
In order for something to be a mixture what must you be able to do?
In order for something to be a mixture you must be able, after you mix the ingredients, to be able to separate them; for ex. raisins and bran flakes
Each criterion must be true for the compound criterion to be true?
Yes, in a compound criterion, each individual criterion must be met in order for the compound criterion to be considered true. If any one of the criteria is not satisfied, then the compound criterion as a whole is considered false.
How can you become exposed chemicals?
In order for a chemical to become hazardous to a person's health, it must first not drink, eat, or smoke in areas where they may be exposed to toxic chemicals.
To separate two liquids by distillation what must be different?
The boiling points of the two liquids must be different in order to effectively separate them by distillation. This allows one liquid to vaporize at a lower temperature and be collected as a separate distillate from the other liquid.
How can you separate the elements in a compound using electricity?
To separate the elements in a compound using electricity, one must first know that this is dangerous and should only be done by science professionals. First electrical currents are applied to the compound and then kept there until the compound separates. As the compounds heat up they will begin to separate.
What properties must a compound have in order to be steam distillable?
For a compound to be steam distillable, it must have a higher vapor pressure than water at the temperature of the steam distillation process. Additionally, the compound should be stable under the conditions of steam distillation, meaning it does not decompose or react with water vapor. Lastly, the compound should have limited solubility in water to allow for efficient separation from the distillate.
Why is breaking down a compound into its elements consid A chemical change?
its simple, seeing as how you are breaking a compound down which consists of 2 pure substances. Means that there is a chemical change via taking one pure substance out which will inturn change it chemically and physically
Why should you not reuse chemicals?
Some chemicals can and must be reused.
What precautions must be taken when using the chemicals and the optional equipment?
the operator must be protected from the splashing of the chemicals
