How many miles of co2 are produced if 5.0 moles of c10h22 react with an excess of o2?

Chemistry

Naily [24]2 years ago

The balanced equation for the above reaction is as follows;
2C₁₀H₂₂ + 31O₂ ---> 20CO₂  + 22H₂O
stoichiometry of C₁₀H₂₂ to CO₂ is 2:20
this means that for every 2 mol of C₁₀H₂₂ that reacts - 20 mol of CO₂ is formed 
therefore when 5.0 mol of C₁₀H₂₂ reacts - 20/2 x 5.0 = 50 mol of CO₂ is formed 
50 mol of CO₂ is produced.

Question 1:  Which of the following is true?

Answer:

            Figure II and Figure IV are both compounds.

Explanation:

                   Compound is a substance which is formed by chemical reaction of different elements.

Example:

              Water  =  H₂O  =  Which is made up of hydrogen and oxygen atoms.

              Carbon Dioxide  =  CO₂ =  Which is made up of carbon and oxygen                       atoms.

In given figures, Figure I and Figure III are not compounds because Figure I is containing a substance which is made up of same atoms like N₂, O₂, Cl₂ and Figure III is containing a substance which is made up of single monoatomic element like Ne, Kr, Xe gases.

Question 2:  Which of the following statement is true?

Answer:

            The Figure is the Molecule and a Compound

Explanation:

                    Molecules are formed when two or more, either same or different atoms join chemically. While, compound is any substance which formed when two different atoms join together chemically.

                    In given figure, it can be seen that the particles are made up of two atoms. Hence, it is said to be a molecule. Also, the atoms which are forming the molecule are different in color means, they are different atoms therefore, it is also called as compound.

Question 3:  Which of the following list includes only molecules?

Answer:

            Third List only include Molecules

Explanation:

                    Molecules are formed by the combination of two or more same or different atoms. In given options;

List 1 is containing a substance ( Mg ) which is existing in monoatomic form. It means we can exclude the first list.

List 2 is containing a substance ( Fe ) which is existing in monoatomic form. It means this list can also be excluded.

List 3 is containing all substances in molecular forms. Like NaCl made up of Na and Cl, N₂ made up of two nitrogen atoms and H₂O (water) made up of two hydrogen and one oxygen atoms.

List 4 is containing a substance ( He ) which is existing in monoatomic form. It means this list can also be excluded.
