The lower the ph of a solution, the a. greater the number of oxygen atoms b. more acidic the solution c. less toxic the solution d. higher the oh— concentration

b.more acidic the solution

Explanation:

pH is the measure of acidity or alkalinity of a solution.  Acids are substances which gives ions when dissolved in water.

pH is calculated by taking negative logarithm of hydrogen ion concentration.

Thus as pH and are inversely related, a solution having lower pH will have more amount of concentration , a lower amount of concentration and will be more acidic.

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.

personal, she chose to do it.
