You will work on this lab individually. You will write a CER using the rubric below. Your claim should address which metal between two is more reactive. Pick from one of the comparisons below. You need to talk to your table mates in
class and pick a different comparison that your table mates. All tables have no more than 6 people and there are 6
choices below. I will give you the first 5 minutes of class on Tuesday 1/11 to figure this out.
My elements are lithium and potassium

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

i do not get it   at all

the correct answer to this question is 2
