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.
20 g of K2C2O4 is reacted with KMnO4 according to the following chemical equation:
K2C2O4 (aq) + 2 KMnO4 (aq) + 8 H2O →10 CO2 (g) + 2 Mn(OH)2 (s) + 12 KOH (aq)
a) How many grams of KMnO4 are required for this reaction?
b) How many grams of Mn(OH)2 will be produced?
c) If the reaction is done in 2.5 L of solution, what will be the concentration of KOH at the end?
d) If CO2 is collected,how many liters of CO2 gas will be formed at STP?
