Four clear solutions are sitting on a lab table. You have the same volume and concentration of each. Two will neutralize each other. Using the pH table, interpret the possible results below and draw conclusions as to which two of the solutions will neutralize each other.

A) Mixing solutions B & D give a pH color similar to solution A.
B) Solution B reveals a dark green during a litmus paper test and Solution C has a pH of 11.
C) Solution A has a pH of 4 and a litmus paper test on solution C gives reveals a blue color.
D) A litmus paper test of solution A shows a yellow-green color and solution D gives dark orange during a litmus test.

b false

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

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 believe the answer is 5,000
