What do the coefficients of a balanced equation represent

Coefficients of a balanced equation represent the amount of moles, that has each reactant and the products that are made

Explanation:

In the reaction:

2H₂ (g) + O₂ (g)  → 2H₂O (g)

2 moles of hydrogen react with 1 mol of oxygen to produce 2 moles of water.

If there is no coefficient, you assume a value of 1.

You can also say, 1 mol of oxygen reacts with 2 moles of hydrogen to produce 2 moles of water.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.

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
