Question 1(multiple choice worth 4 points) (04.02 lc) which of the following is a synthesis reaction? bao + co2 β†’ baco3 ch4 + o2 β†’ co2 + h2o feco3 β†’ feo + co2 2nh3 β†’ 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 β†’ 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) β†’ nh3(g) 2n(g) + 3h2(g) β†’ 2nh3(g) 2nh3(g) β†’ n2(g) + 2h3(g) 2nh3(g) β†’ 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) β†’ 2koh(aq) + h2(g) is a decomposition reaction. true false

Amines are good nucleophiles, even though they are neutral molecules. how would the rate of an sn2 reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? amines are good nucleophiles, even though they are neutral molecules. how would the rate of an reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? because both reactants in the rate-limiting step are neutral, the reaction will be faster if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will be slower if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will occur at the same rate if the polarity of the solvent is increased. request answer
