Alexis Becker Pre-Lab Experiment 7 Avinash Pallagani Investigating Stoichiometry with sodium salts of carbonic acid 4/2/14 A summary of the concepts: The purpose of this lab is to better understand “stoichiometry”. We will be reacting sodium carbonate (NaHCO)3 and sodium carbonate (Na2CO3) with hydrochloric acid to produce sodium chloride‚ water‚ and carbon dioxide. The balanced chemical reaction looks like this: NaHCO3 + HCl = NaCl + H2O + CO2 CAUTION: Be especially

Pre-Lab Work Sheet Which type of compound usually has higher melting points: ionic compounds or covalent compounds? What is the reason for this difference in melting points? (3 points) Ionic compounds have higher melting and boiling points than covalent compounds. The electrostatic attraction in an ionic bond is very strong hence a lot of heat energy is required to break it down‚ ionic bonds have high melting and boiling points. In covalent bonds‚ the intermolecular forces are very weak and
