Combustion between Propane and Oxygen?

The belated picture shows 3 molecules of propane and 10 molecules of oxygen.

A.

10 molecules of oxygen would react completely with 10 x (1/5) = 2 molecules of propane, but there is more propane present than that, so propane is in excess and O2 is the limiting reactant.

B.

(10 molecules of O2) x (3 mol CO2 / 5 mol O2) = 6 molecules CO2

(10 molecules of O2) x (4 mol H2O / 5 mol O2) = 8 molecules H2O

3 molecules C3H8 initially – 2 molecules C3H8 reacted = 1 molecule C3H8 left over

No molecules of O2 will be left since O2 is the limiting reactant.

[I hope the comments aren’t important. YA won’t show them to me, so I haven’t seen them.]

Consider the mixture of propane, C3H8, and O2 (figure

Consider the mixture of propane, C3H8, and O2 (figure – consider the mixture of propane, C3H8, and O2 (figure shows 10 O2 molecules and 3 propane molecules). C3H8 + 5O2 —> 3CO2 + 4H2O O2 – limiting reactant how many molecules of CO2, H2O, C3H8, and O2 will be present if the reaction goes to completion? 3,4,0,0 – incorrect; 6,8,5,0 – incorrect;…How many molecules of CO2, H2O, C2H5OH, and O2 will be present if the reaction goes to completion? 4,6,0,1 molecule. Aluminum sulfide reacts with water to form aluminum hydroxide and hydrogen sulfide. Write the balanced chemical equation for this reaction.We need 0.500mol O2 to consume all of the C3H8. Therefore some C3H8 will be unconsumed. moles C3H8 consumed = 0.100mol O2 * (1 mol C3H8 / 5 mol O2) moles C3H8 consumed = 0.020mol C3H8. moles C3H8 unconsumed = 0.100mol C3H8 – 0.020mol C3H8. 0.080mol C3H8 remains and 0.000mol O2 remains. 2. As I have shown above, O2 is totally consumed and C3H8

chem 111 Flashcards | Quizlet – the complete reaction is for the combustion of C2H5OH. C2H5OH + 3O2 —–> 2CO2 + 3H2O. Therefore, the number of molecules of CO2 = 2 , H2O= 3 , C2H5OH= 1, and O2= 3 will be present if the reaction goes to completion.In this video we'll balance the equation C3H8 + O2 = CO2 + H2O and provide the correct coefficients for each compound.To balance C3H8 + O2 = CO2 + H2O you'll…Use the reaction shown below to answer the next 3 questions: 2 C 2 H 6 (g) + 7 O 2 (g) fi 4 CO 2 (g) + 6 H 2 O (g) 8. How many moles of water can be produced when 1.8 moles of C 2 H 6 are used? 26 1.8 mol CH 2 26 6 mol HO x 2 mol CH 2 = 5.4 mol HO 9. How many moles of CO 2

C3H8 + 5O2 =3CO2 +4H2O 4.41 grams of C3H8 and 3.20 grams – The balanced reaction is as follows: C3H8+5O2→3CO2+4H2O A. What is the limiting reactant? B. How many molecules of CO2,H2O,C3H8, and O2 will be present if the reaction goes to completion? Please show how you did this! A little lost.4NH3+5O2 = 4NO + 6 H20 If a container were to have 10 molecules of O2 and 10 molecules of NH3, initially, how many total molecules (reactants plus products) would be present in the container after this reaction goes to completion? Chemistry. A solution containing equal masses of glycerol, C3H8O3, and water has a density of 1.10 g/mL.Molecules of CO₂, H₂O, C₂H₅OH, and O₂ will be present if the reaction goes to completion are . 0 molecules C₂H₅OH. 0 O₂ molecules 2 and CO₂ molecules 3 H₂O molecules Further explanation The reaction equation is the chemical formula of reagents and product substances the reaction coefficient is a number in the chemical
