Balance the reactions. A hint is provided to help you decide if the reaction will proceed as written, ie from left to right. Do not leave any fractions. 1. a) Balance Al₂O3 → Al + 0₂ b) What type of reaction is this? c) Is this a redox rx, yes / no ? d) The reaction will go from left to right, yes / no ? (hint: O₂ is very reactive) 2. a) Balance HNO3 + AI → b) What type of reaction is this? c) Is this a redox rx, yes / no ? d) The reaction will go from left to right, yes / no ? (hint: aluminum is a reactive metal, and a gas escapes) C7H14 + 0₂ 3. a) Balance, leave no fractions b) What type of reaction is this? c) Is this a redox rx, yes / no ? d) The reaction will go from left to right, yes / no ?
