what is the percent composition of oxygen in glucose, C6H12O6
Suppose we have a 12.2-L sample containing 0.50 mol oxygen gas (O2) at a pressure of 1 atm and a temperature of 25ºC. If all this O2 were converted to ozone (O3) at the same temperature and pressure, what would be the volume of the ozone
A bacteria triples every 15 minutes. If there were originally 45 cultures in the lab, write the exponential function then determine how many cultures there are after 5 hours.
