A sample of ethanol (C2H60) has a mass of
0.2301 g. Complete combustion of this sample
causes the temperature of a bomb calorimeter to
increase by 1.33°C. The calorimeter has a mass
of 2.000 kg and a specific heat of 2.45 J/g.°C.
What is the heat of combustion for this sample?
kJ

explanation:

crosscutting concepts have application across all domains of science. as such, they are a way of linking the different domains of science. they include patterns; cause and effect; scale, proportion, and quantity; systems and system models; energy and matter; structure and function; and stability and change.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
