Acertain oxygen atom has the electron configuration 1s22s22px22py2. how many unpaired electrons are present? 2 incorrect: your answer is incorrect. is this an excited state of oxygen? yes no in going from this state to the ground state would energy be released or absorbed? neither, the oxygen atom is in the ground state. energy would be absorbed. energy would be released.

The equation below shows a chemical reaction. a + b + heat —> c + d according to the law of conservation of energy, which statement is true? a. the reactants absorb heat because they have less energy than the products. b. the products release heat because they have more energy than the reactants. c. the reactants generate heat because they have more energy than the products. d. the products require heat to form because they have less energy than the reactants.
