Which process involves a decrease in the dispersal of matter? Select the correct answer below: heat exchange between two solids

The options are

A.heat exchange between two solids

B.the decomposition of a compound into its constituent elements

C.the precipitation of a solid

D.none of the above

The answer is

C.the precipitation of a solid

Dispersal of matter involves the process whereby there is more space occupied by the resulting element/compound than the initial one. For example the conversion of liquid to gas means that it has an increase in the dispersal of matter as the gas particles will contain more space when compared to a liquid.

Precipitation of a solid means conversion of a liquid to a solid. A liquid is known to contain more space which means there is a decrease in the dispersal of matter.

the element that provides strength to the exoskeletons of clams and oysters is phosphorus.

this is so because calcium carbonate is the main component in the shells. calcium carbonate is strengthened by phosphorus.

explanation:

due to the fact that it skipped a generation we can tell it is definitely not a dominant trait, therefore it must be recessive. i think this is right let me know!
