The number of moles of CaCO3 in the Tums, equal to the number of moles in CO2 produced. Therefore, used the PV=nRT idea gas law converted to n=(PV)/RT to find the number of moles in CO2. ... CO2 number of moles was 0.008442mol. Then, we used number of molecules and molar mass of CO2 to find mass of CO2. As the CO2 equals CaCO3 number of molecules, we multiply the CO2 number of molecules by the molar mass of CaCO3 100.086g. ...

Chemical reactions in plants (photosynthesis) convert this light into stored chemical energy. ... Sloan (1970) states that before either glucose or glycogen can be used to generate energy; they must be converted to a compound called glucose-6-phosphate. The conversion of a molecule of glucose requires 1 molecule of ATP but the conversion of glycogen doesn't require any energy'. ... From this process 3 moles of ATP are formed for each mole of glycogen broken down. If glucose is used then only 2 moles of ATP are formed because 1 mole is used in the conversion of glucose into glucose-...

This molecule has a molat mass that is about the same as the weighted aberage of teh molecules within the gasoling. the other reactant in gasoling combustion is oxygen, which is only twenty point nine percent of air by volume. ... EXAMPLE #1 CH4 + 2O2 --> CO2 + 2H2O 10.0 grams of methane has a molecular weight of 16.04 g/mole 10 grams divided by 16.04 grams per mole = 0.623 moles of methane. The ratio of methane to water is 2 water for every 1 methane, so you should expect to form 0.623 moles CH4 times 2 moles H2O/1 mole CH4 equals 1.25 moles H2O We now have to convert back to grams: the...

The electrolytic cell converts electrical energy in to chemical energy, thus the electrodes must be conductive. ... The potential difference is controlled in the plating process; a low amount of constant voltage is preferable as it provides enough efficiency of metal deposition however, does not distribute enough energy to cause a large sub-reaction with the water molecules of the electrolyte solution. ... For example, if there was not a metallic ion close to the cathode and the electrons had built up due to constant current; the electrons would bond to the water molecules and produce hydrogen...
