Two negatively charged objects are brought near each other and then repel each other Which of these statements explains this?

Select one

1.Two electrical fields of energy push against each other and force the objects apart

2.Two electrical fields of energy pull towards each other but then switch and this suddenly forces the objects apart.

3.Two electrical energy fields create force fields that surround the two objects

4. The electric energy fields intertwine to create a magnetic field that pushes the two apart.

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

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042

0.42

2.4

24

the correct answer would be b) volume versus temperature, because they are also directly proportional.
