ammonium carbonate Correct Answer-(NH4)2CO3 Heisenberg Uncertainty Principle Correct Answer-Cannot know both the momentum and position of an object with absolute certainty Bose-Einstein Principle Correct Answer-Collection of atoms cooled close to absolute zero will coalesce into a single quantum state Le Chatelier's Principle Correct Answer-reversible process, the application of stress to the system will cause the system to respond in a way that will relieve this stress Pauli Excl...

Dynamic Equilibrium Exam with Questions and Answers Dynamic equilibrium ANSWER Forward and backward reaction will be going at the same rate Can only occur in a closed system Le Chatelier's principle ANSWER If there's a chanhe in concentration, pressure or temperature, the equilibrium will move to counteract the change Increasing concentration of reactant ANSWER Equilibrium shifts to the right to get rid of extra reactant by making more product Increasing concentration of prod...
