In which way does electricity flow in a DC circuit? * From the negative terminal of the battery to the positive one
From the positive terminal of the battery to the negative one
The electricity flows first from the negative terminal to the positive one, then the
polarity switches
The electricity flows first from the positive terminal to the negative one, then the
polarity switches

From the negative terminal of the battery to the positive one

Explanation:

   DC is just  dirrect current that has e- flowing from the negative terminal to the positive.

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
