Which of the following is a synthesis reaction? bao + co2 → baco3 ch4 + o2 → co2 + h2o feco3 → feo + co2 2nh3 → 2n2 + 3h2 question 2(multiple choice worth 4 points) (04.02 lc) what is true of synthesis and decomposition reactions? synthesis reactions require more energy than decomposition reactions. synthesis reactions produce more products than decomposition reactions. synthesis reactions are the opposite of decomposition reactions. synthesis reactions have fewer reactants than decomposition reactions. question 3(multiple choice worth 4 points) (04.02 mc) an unbalanced chemical equation is shown: 2nan3 → 2na + n2 which of the following statements explains why the equation is not balanced? four molecules of n2 should be produced during the decomposition. three molecules of n2 should be produced during the decomposition. four molecules of n2 should be produced during the synthesis reaction. three molecules of n2 should be produced during the synthesis reaction. question 4(multiple choice worth 4 points) (04.02 mc) which chemical equation correctly represents the reaction that takes place when nitrogen gas and hydrogen gas are formed as ammonia decomposes? n(g) + h3(g) → nh3(g) 2n(g) + 3h2(g) → 2nh3(g) 2nh3(g) → n2(g) + 2h3(g) 2nh3(g) → n2(g) + 3h2(g) question 5 (true/false worth 2 points) (04.02 lc) a synthesis reaction can be identified because it only has pure elements on the left side of the arrow and compounds on the right side of the arrow. true false question 6 (true/false worth 2 points) (04.02 lc) the reaction k(s) + 2h2o(l) → 2koh(aq) + h2(g) is a decomposition reaction. true false
