A student is given two beakers. The first contains a 2M solution of an acid. The second a 2M solution of a base.
A) Which has the lowest pH?
B) Which has the highest hydronium concentration?
C) In which is the water acting as a base?

The answer to your question is below.

Explanation:

a) pH is a scale to measure the acidity or basicity of a solution. It goes from 0 to 14. Acid solutions have a lower pH than basic solutions.

Then, the 2 M acid solution has a lower pH

b) Hydronium ions are represented by [H₃O⁺]  and are characteristic of acids. So the concentration is higher in the solution 2 M of an acid.

c) Also, the answer is the 2 M solution of an acid.

idk i’m struggling too

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
