b) Using stoichiometry, determine the theoretical yield of hydrogen gas (in moles) that will be produced by the complete reaction of the aluminum metal. c) Refer to Table 1 and calculate the partial pressure of hydrogen gas. O Using the Ideal Gas Law, determine the experimental moles of hydrogen gas collected. Calculate the % yield of the reaction based on the actual yield (d) and the theoretical yield (b) calculations above.

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.
