Fern Hill Lake has a low pH, presumably the result of acid rain. The lake is about 3 kilometers long, 2.5 kilometers across, and has an average depth of 8 meters. Its pH is 4.1. Someone in your community proposes that calcium hydroxide be added to the lake to increase the pH to 6.5, a more favourable level. *About how many grams of calcium hydroxide should be added to the lake to accomplish this task? *What approximations must you make in your calculations? Hoe reasonable do you think your approximations are? *Is adding calcium hydroxide a long-term solution to the problem of acid rain?
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
