I think it is "Known".
Radioactive decay is measured using a formula where the half-life <span>of an isotope is the time it takes for the original nuclei to decay half of its original amount.</span>
Answer:
A. Hydrogen cans oxygen are reactants
Explanation:
Oxygen has a charge of -2. Hydrogen has a charge of +1. So it takes two hydrogens to balange the one oxygen hence the H20. So the reaction is balanced, and H20 is indeed made up of 1 oxygen and 2 hydrogen atoms. The equation 2 hydrogen + 1 oxygen (<---reactants) = Water (<--product) So hence Hydrogen cans oxygen is not a true statement. If cans is a misspelling then C would be your answer.
Hope that helped

Answer:
20 pretzels.
Explanation:
So in the first bag there at 64 pretzels in 16-ounces.
