Hydrogen-3 has a half-life of 12.35 years. what mass of hydrogen-3 will remain form a 100.0 mg initial sample after 5.0 years? a) 7 mg b) 24 mg c) 76 mg d) 18 mg

that would be b i just took the test : )

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )
