Show your complete solution and express your final answer in two decimal places. In a laboratory, a 16.1 g of solid aluminum reacts with oxygen gas to produce 37.5 g of Al2O3. After the experiment, it was found out that only 36.99 g of Al2O3 was created. The reaction between these two substances are chemically represented as: _______ Al(s) + _______ O2(g) → _______ Al2O3(s) Balance the chemical equation. Find the molar mass of Al2O3. What is the theoretical yield and the actual yield of Al2O3? What is the percent yield of this reaction?
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.
