FRQ #3 a.) The first property of water is its polarity. A water molecule is formed by one oxygen atom covalently bonded to two hydrogen atoms. The electronegativity of the oxygen atom creates an unequal sharing of electrons between the O and H atoms of the molecule. This also gives water the ability to form hydrogen bonds between the slightly negative oxygen atom and the slightly positive hydrogen atom. Water has a high specific heat due to the hydrogen bonds. Because of this‚ water requires

Biology 20 IB Design Lab Does increasing or decreasing the ph level of a 3% concentration H2O2 (l) solution affect the amount of oxygen released between 15.0ml of the solution and a 5g sample of liver? The reaction is measured by the difference in mass of a balloon that is used to capture the amount of gas released by the catalase enzyme found in liver reacting with a basified 3% H2O2 (l) and an acidified 3% H2O2 (l) . Chemical reactions occur when two or more molecules interact and the molecules
