A12-volt car battery pushes a charge through the headlight circuit with a resistance of 8.5 ohms. how much current is passing through the circuit

= 1.41 A

Explanation:

Using the Ohm's law;

V = Ir

where V is the potential difference or voltage

I is the current in Amperes and

R is the resistance in Ohms

In this case; V = 12 V, I = ? and R = 8.5 Ohms

I = V/R

 = 12/8.5

 = 1.41 A

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

particle   p is an electron and particle q is a neutron
