How many argon atoms are contained in 7.66 x 105 mmol of argon?

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.

the maximum mass of nh3 is nh3 in grams

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 .
