1. Provide a balanced molecular equation for these written chemical r eactions. Include states of matter. A. When liquid propanol reacts with gaseous oxygen, gaseous carbon dioxide and gaseous water are produced. B. When aqueous sodium hydroxide reacts with aqueous sulfuric acid, aqueous sodium sulfate and liquid water are formed. C. When fluorine gas is put into contact with solid calcium metal, solid calcium fluoride are formed. D. When aqueous hydrochloric acid reacts with sodium sulfide, gaseous hydrogen sulfide and aqueous sodium chloride are formed. E. When sodium metal reacts with aqueous iron (II ) chloride, solid iron metal and aqueous sodium chloride are formed. �) �WA.O \-1 °1. t l-11,SO� '1. f\l"' ---- / � 0 - A J- lt/ j Y � O tt ., 1 --, C.)

4 ) In class, I told you that we would only consider strong acids in neutralization reactions. Let's consider what would happen if we use a weak acid in a neutralization reaction. As an example, let's consider HF, which does not completely dissociate in water. Keeping that in mind, write the molecular, complete ionic, and net ionic equations for the following neutralization reaction between HF and NaOH. �Tni6 \� �W '601\'\LTI'll,. 1'\a.t (M�l� �t­ � Y\Dt� � �\A.Lt.., 14 �1�""""°"'�
