how could measure whether or not the chemical reaction that breaks down hydrogen peroxide is occurring
d1i1m1o1n [39]

Answer:

You could check the pH!

Explanation:

This is an idea, when you break down H2O2 (Hydrogen peroxide) you will be left with H2O (Water) and O2 (Oxygen gas). H2O2 theoretically would have a lower pH than water. Water has an average pH of around 7 while H2O2 will have a pH of about 4.5.

So theoretically to figure out if hydrogen peroxide is being broken down you can test for the pH. This is a very simply process, you just stick a little peice of litmus paper into the solution and immediatly it will change color to tell you the pH.

Compare energy transfer in a food chain to energy transfer in a food web
Ket [755]
Energy flows up a food chain, from the primary producers to the primary consumers, to the secondary consumers, up to the tertiary and then quaternary consumers. Energy flows when one organism eats another lower in the food chain, the energy is transferred by heat and movement, some though is lost. They eat each other but it only gets half the energy stored. A food web is similar - it is just a series of food chains.
