The variables for this experiment include mass, volume and the materials in the various balls, as well as their densities. In Part II, you will be comparing an inflated football with a deflated one. Use the drop-down menus to
complete the sentences and identify the independent and dependent variables.
In Part II, the independent variable, the one that is intentionally manipulated, is
In Part II, the dependent variable, the one that you measure the response in, is

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.

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.
