Vinegar is an aqueous solution of acetic acid (hch3coo). when vinegar reacts with dry baking soda (nahco3), the result is an aqueous solution of sodium acetate (nach3coo), liquid water, and carbon-dioxide gas, which bubbles out of the solution. which chemical equation correctly represents this reaction?

its a

Explanation:

The correct representation of reaction will be:

Explanation:

When vinegar that is 10 percent solution of acetic acid reacts with baking soda results in evolution of carbon-dioxide gas along with formation of sodium acetate solution.

Baking soda = sodium bicarbonate

The chemical reaction represented as:

1.solid

2.carbon dioxide

3.helium

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
