For each chemical reaction listed in the first column of the table below, predict the sign (positive or negative) of the reaction entropy δsrxn. if it's not possible to decide with the information given, check the "not enough information" button in the last column. note for advanced students: assume the temperature remains constant. assume all gases and solutions are ideal. reaction sign of reaction entropy not enough information. an0 nacl (s) → na+ (aq) + cl-(aq) not enough information. 4pci 3(g) → p4(g) + 6cl2(g) not enough information.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
