How many total molecules will be present when the reaction of 5,000 molecules of CS2 with 15,000 molecules of O2 goes to completion?

Question

Helmer · Answer

Explanation:

When the reaction of 5,000 molecules of CS2 with 15,000 molecules of O2 goes to completion in the reaction CS2 + 3O2 --> CO2 + 2SO2, a total of 15,000 molecules will be present. This total is made up of 5,000 molecules of CO2 and 10,000 molecules of SO2. Chemical Balancing: In chemical reactions, the number of reactant molecules must be balanced with the product molecules according to the stoichiometric coefficients, which are the numbers in front of molecules in the reaction equation. In this case, the given reaction is: CS2 + 3O2 --> CO2 + 2SO2.

In this reaction, 1 molecule of CS2 reacts with 3 molecules of O2 to form 1 molecule of CO2 and 2 molecules of SO2. Therefore, for every 1 molecule of CS2, you will get 1 molecule of CO2 and 2 molecules of SO2.

Given that there are 5,000 molecules of CS2 and 15,000 molecules of O2 initially, and assuming the reaction goes to complete completion, all of the CS2 and O2 molecules will be used up. As a result, you will have 5,000 molecules of CO2 (1 CO2 for each CS2) and 10,000 molecules of SO2 (2 SO2 for each CS2), totaling 15,000 molecules in total.
