A Geiger-Müller counter, used to detect radioactivity, registers 14 units when exposed to a

radioactive isotope. What would the counter read, in

units, if that same isotope is detected 60 days later?

The half-life of the isotope is 30 days.

Significant figures are digits read directly from the measuring instrument plus one more digit, which is __ by the observer.

What will most likely happen when two bromine atoms bond together?

Substance a is a nonpolar liquid and has only dispersion forces among its constituent particles. substance b is also a nonpolar liquid and has about the same magnitude of dispersion forces among its constituent particles. when substance a and b are combined, they spontaneously mix.
