This is the chemical formula for acetic acid (the chemical that gives the sharp taste to vinegar): CH3CO2H An analytical chemist has determined by measurements that there are 8.64 moles of carbon in a sample of acetic acid. How many moles of hydrogen are in the sample? Round your answer to 3 significant digits.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.

ok whats the question if not i cannot you i need question and need a thing to answer

alchemy was - but as new rules were discovered it either changed into chemistry or it became "unscientific".
