How many grams of oxygen (O) are present in a 6.41 g sample of potassium nitrate (KNO3)? Enter your answer in decimal form with the correct number of sig figs. Use the proper abbreviation for the units. NOTE: If you have taken chemistry before and know what diatomic means, do not take that into consideration. Use just O for this. There are reasons for this.
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.
