How often do you need answers to your chemistry questions? Students face difficulties over and over again when solving their chemistry problems. One solution is to get answers to chemistry questions online. There are few resources that offer chemistry answers for free, and sometimes it takes hours to find an answer to the exact chemistry question you have. Some students need AP chemistry free response answers, some search for chemistry quiz answers or even exam review answers, while others have a hard time answering their chemistry worksheets or homework assignments. Chances are that someone has already asked for a solution to your chemistry problem, or at least to a similar one, and you will be able to view the answer online. However, more often than not, students realize that the answer to this particular chemistry question is nowhere to be found. We offer the perfect solution to your struggle with chemistry. If you have a problem in any branch of chemistry, including General, Organic, Inorganic, Analytical, Physical and Macromolecular Chemistry, and Biochemistry, our experts will gladly offer their professional help. Ask your question here and get chemistry answers quickly and to the point. If you need a solution to more advanced problems, such as AP chemistry free response questions, order now, and our chemistry experts will help you for a reasonable price.

The heat of reaction for a chemical reaction can be calculated by finding the sum of the bond energies of the products and subtracting that from the sum of the bond energies of the reactants:

Heat of reaction==Sum of the energy for the bonds broken − Sum of the energy for the bonds formedSum of reactant bond energies − Sum of product bond energies

When calculating the sum of the bond energies, each bond in the reaction must be accounted for. For example, CH4 is a reagent with a coefficient of 1 in the reaction. There are four C−H bonds in methane and one methane molecule per reaction, for a total of four C−H bonds on the reactant side. All four bonds must be accounted for when finding the sum of the bond energies for the reactants.

Calculate the heat of reaction using the average bond dissociation energies given in the introduction and your answer to Part B for the reaction

CH4 + 2O2 → CO2 + 2H2O
Express your answer in kilojoules per mole to three significant figures.

Thanks so much! My professor was so impressed with the assignment you’ve solved for me… You’ve followed all my wishes and even proceeded with better ideas. That’s what I call a really good job! And the price was pretty reasonable. I’ve never tried services like this before. But now it will be my usual practice. And even more I will use exactly your service! And I’ll tell all my friends to do so. They’ll check it out for sure. Cheers!
