What is an aqueous solution? what is an aqueous solution? an aqueous solution is a homogeneous mixture of a substance with water. an aqueous solution is a dispersoid solution. an aqueous solution is a mixture of a liquid substances. an aqueous solution is a heterogeneous mixture of a substance with water.

The answer to your question is: first option.

Explanation:

What is an aqueous solution?

Aqueous solution is a solution which solvent is water and is homogeneous.

a) An aqueous solution is a homogeneous mixture of a substance with water.  This is the correct definition of aqueous solution because it mentions the characteristics of this kind of solutions.

b) An aqueous solution is a dispersoid solution. This option is wrong, it is a homogeneous solution, and the description do not mention water.

c) An aqueous solution is a mixture of a liquid substances. Aqueous solution is a mixture but one of the components is water not a liquid substance.

d) An aqueous solution is a heterogeneous mixture of a substance with water. Aqueous solution is homogeneous not heterogeneous, this option is wrong.

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
