Concept Review Chapter 9
potassium chloride + silver nitrate potassium nitrate + silver chloride • Look up each part: • potassium • chloride • silver • nitrate + - + • • • - + - KCl + Ag. NO 3 KNO 3 + Ag. Cl Symbol K 1+ Cl 1 Ag 1+ NO 31 ALL THE FORMULAS ARE BALANCED! IS THE EQUATION BALANCED?
Aluminum hydroxide + sodium nitrate aluminum nitrate + sodium hydroxide. Aluminum hydroxide sodium nitrate Al 3+ OH 1 Na 1+ NO 31 Now all the compounds are balanced! Balance the equation. 1+ 3+ 1 - Al(OH )3 + 1 - 3 Na NO 3 1 Al, 3 OH, 3 Na, 3 NO 3 REACTANTS 3+ 1+ 1 - 1 - Al (NO 3)3 + 3 Na. OH PRODUCTS
