In a chemical reaction, reactants that are not used up when the reaction is complete are called excess reagents. To calculate the excess reagent, you need to find molecular weight then work out molarity.
To react with all of the chlorine you would need 0.3 mol of aluminum, and there are 0.93 moles of aluminum. This confirms that there is enough aluminum to react with all of the chlorine. Chlorine is the limiting reactant, and aluminum is the excess reactant. References Chemistry LibreTexts...
Use the following equation: 4Fe(g) + 3O_2 (g) \to 2Fe_2O_3(s) If 32 moles of Fe and 27 moles of O_2 are reacted, which is the limiting reagent? For the following reaction, calculate how many moles of each product are formed when 0.356 moles of PbS completely re...

Though we did not, ourselves, calculate the COSMO-RS corrections, the use of these led to remarkable quality. The discussion by Sure and Grimme seemed, however, to indicate that this success might depend on the parametrization set utilized. A hybrid solvation model was also considered, where ...
The maximum tricuspid regurgitant jet velocity (TRV) was obtained by continuous-wave Doppler over the tricuspid valve and was used to calculate the pulmonary artery pressure (PAP) via the formula 4 × TRV2. Finally, in order to correctly estimate the sPAP, it was necessary to determine the...
Let us, however, underline that experimentally it is more difficult to determine the amount of waste in a process (required to calculate E factor) than the amount of entering materials (required to calculate PMI). 5. The EcoScale When a more exhaustive determination of the greenness of a ...
