A 0.765-gram sample of impure potassium chlorate KClO3was decomposed by thermal decomposition into oxygen gas and potassium chloride. The oxygen, 222.50 mL was collected in a eudiometer over water at a temperature of 20.00 C and a pressure of 777 mm Hg. The water level in the eudiometer is 42.2 mm above the water level in the beaker. The vapor pressure of water at this temperature is 17.54 mm Hg Determine the purity of the original potassium chlorate sample
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.
