a)
Interpretation:Vapor pressure as applied to melting should be defined.
Concept introduction:Changes that involve no transformation of one substance into another are called physical changes. In these changes, size and shape of matter are changed but these are not accompanied by
b)
Interpretation:Melting point or melting point range should be defined.
Concept introduction:Changes that involve no transformation of one substance into another are called physical changes. In these changes, size and shape of matter are changed but these are not accompanied by chemical reactions. Melting of ice, boiling of water, dissolution of sugar into water are some examples of physical changes.
c)
Interpretation:Mixed melting point should be defined.
Concept introduction:Changes that involve no transformation of one substance into another are called physical changes. In these changes, size and shape of matter are changed but these are not accompanied by chemical reactions. Melting of ice, boiling of water, dissolution of sugar into water are some examples of physical changes.
d)
Interpretation:Eutectic point should be determined.

Determine the Ka of the acid.arrow_forwardAs the lead product manager at OrganometALEKS Industries, you are trying to decide if the following reaction will its major product: 2,0° with a new C-C bond as If this reaction will work, draw the major organic product or products you would expect in the drawing aree below. If there's more than one major product, you can draw them in any arrangement you like. Be sure you use wedge and desh bonds if necessary, for example to distinguish between major products with different stereochemistry. If the major products of this reaction won't have a new C-C bond, just check the box under the drawing area and leave it blank.arrow_forward
