The compound tin(II) fluoride is produced according to the following reaction: Sn (s) + 2 HF (g) --> SnF2 (s) + H2 (g) If 45 grams of HF reacts with Sn, How many grams of SnF2 will be produced? a. 353g
b. 176 g
c. 5.7 g
d. 11.5 g

answer; /// the amount of material dissolved in a measure of liquid(concentration) the above statement is (true); /// good luck

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
