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.
In order to prepare for a qualitative analysis experiment, Felix is predicting whether small samples of several pairs of 0.10 M control solutions will form a precipitate when mixed. He uses the table of solubility values provided as well as the general solubility guidelines in the chempendix.
Solubilities of Alkaline Earth Salts (g/100 g H2O, at 20−25∘C)
OH− CO2−3 SO2−4 CrO2−4 C2O2−4
Mg2+ 0.00069 0.18 35.7 54.8 0.038
Ca2+ 0.16 0.00066 0.205 13.2 0.00061
Sr2+ 2.25 0.00034 0.135 0.106 0.005
Ba2+ 4.91 0.0014 0.00031 0.00026 0.0075
For each pair of compounds, predict the formula for the precipitate that Felix will see when he mixes the solutions in lab. If no precipitate forms, enter NP for no precipitate.
