your teacher asks you to mix two compounds to find out if the reaction is endothermic or exothermic
what will you do to determine which type of reaction is occurring?
5
you are investigating the reaction rate of a chemical reaction
how might the required activation energy be affected if you add a catalyst to the reaction? if you add a inhibitor to the reaction?

Choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. a 1.0 kg block is placed on top of a 2.0 kg block. a horizontal rope pulls the 2.0 kg block across a frictionless floor with a force of 21.0 n. the coefficient between the two blocks is 0.75. does the 1.0 kg block on top slide?
