If the resulting ph is 7, it was most likely a titration. a. strong acid, strong base b. strong acid, weak base c. weak acid, strong base d. weak acid, weak base

a. Strong acid, strong base

Explanation:

pH = 7 , is the neutralization point , where , the concentration of Hydronium  ions ( H⁺ ) becomes equal to the concentration of the hydroxide ions ( OH⁻ ) .

In case of strong acid and strong base ,

The acid and the base will dissociate completely , and will give the corresponding ions , i.e. , the ( H⁺ ) and ( OH⁻ ) , which will combine to give water , which has a pH of value 7.

In case of weak electrolytes , there wont be complete dissociation and the ions generated wont be enough to generate water of pH 7 .

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.
