This is the chemical formula for acetic acid (the chemical that gives the sharp taste to vinegar): CH3CO2H An analytical chemist has determined by measurements that there are 38. moles of oxygen in a sample of acetic acid. How many moles of hydrogen are in the sample? Be sure your answer has the correct number of significant digits.
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.
