A student prepared benzil according to the experimental procedure using 2.58 g. of benzoin and 12 mL of nitric acid. The mass of the crude benzil product was 2.25 g. and the mass of the recrystallized benzil product was 1.95 g. Find the molecular weights for benzoin and benzil, then answer the following questions. What was the percent yield of the crude benzil? Assume units of %. Round answer to the first decimal place. What was the percent yield of the purified benzil? Assume units of % Round answer to the first decimal place. What was the percent recovery of the purified benzil from the crude benzil? Assume units of % Round answer to the first decimal place
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.
