The hypothesis states that the fraction of
radioactive nuclei after n half-lives is 0.51
In this expression, the value 0.5 represents
the fraction of nuclei still radioactive after any
half-life cycle.
the fraction of nuclei still radioactive at the
start of the experiment.
the amount of time it takes half of the
radioactive atoms to decay.
the number of half-life cycles.
DONE

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.
