I'm doing an experiment and it's about sand and salt I just need someone to answer these questions for me. Where is the salt after you filter the mixture?

Why was the sand able to be filtered out?

How could you separate the salt from the water?

What other mixtures can be separated by filtering?

Besides filtering, name two other processes that can separate a mixture.

What did you find out from this investigation? Be thoughtful in your answer.

i think   the answer is c hope i'm right

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 just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year
