Convert 75 mL of water to gallons (show work)

Explanation:

1 mL = 0.000264 gallons

Multiplying both sides by 75

75 mL = 0.000264 * 75 gallons

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.
