Calculate the heat of formation for pentane (C5H12) 5C (s) + 6H2 (g) →C5H12 ; ∆Hf = ?

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

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 .
