5. Fe + Br 2 FeBr 3type: ____________IV.Activity SeriesUse the activity series to write balanced chemical equations for each of thesesingle replacement reactions. If no reaction will occur, write “NR”.1. Sn(s) + NaNO 3 (aq) 2. Cl 2 (g) + NaBr(aq) 3. Cu(s) + FeSO 4 (aq) V. Word EquationsSubstitute symbols and formulas for words and then balance the followingequations. Be sure to use abbreviations to denote physical states.1. When solid potassium nitrate is heated, it decomposes to solid potassium nitrite,and oxygen gas is evolved.2. Solid lithium hydroxide reacts with carbon dioxide to form solid lithium carbonateand liquid water.CHEMISTRY: A Study of Matter© 2004, GPB6.37

VI.Predicting Products1. In a common synthesis reaction, sodium metal is lowered into a bottle of chlorinegas. Predict the product, substitute symbols and formulas for names, and thenbalance the equation. Be sure to use abbreviations to denote physical states.2. Aluminum sulfate and calcium hydroxide are used in a water purification process.When each is dissolved in water, they react to produce two insoluble products.Predict the products, substitute symbols and formulas for names, and then balancethe equation. Be sure to use abbreviations to denote physical states.CHEMISTRY: A Study of Matter© 2004, GPB6.38
