Water (H2O) and hydrogen fluoride (HF) are both polar molecules. Which of the following statements are true about the attractions between water and hydrogen fluoride when they are mixed together? Choose the two statements that apply. (Hint: In HF, the F atom attracts the shared electron more than the H atom.) A. The H in HF and the H in H2O attract each other.
B. The H in HF and the O in H2O attract each other.
C. The F in HF and the H in H2O attract each other.
D. The F in HF and the O in H2O attract each other.

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

im doing test rn im going with 2 but ill give answer if itss wrong,   : )
