Two minerals can have the same chemical formula, and yet have different crystalline structure because of the way the atoms of the composition are bonded together. Diamond and Graphite are an example of two minerals with the same composition (Carbon) but different crystalline structure, so they are called:.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
