How many kilojoules of energy are released from the carbon carbon single bonds when glucose (C6H12O6) is burned???
i asked this before but i don't really understand it any better.
can someone please explain it differently
thanks
I don't know who answered your question nor what the answer was. You must look up the energy of a C-C bond (your text should have a table of bond energies and that will list the C-C bond). My book shows that as 347 kJ/mole. Here is a site that shows the glucose molecule.

Note that if we draw the C-C bonds in a straight line, something like this,
C-C-C-C-C-C, there will be 5 bonds to break; therefore, multiply 347 kJ/mole x 5 bonds = ?? kJ/mole for glucose. Having said all of this, there is no real answer for your question since you don't list the amount of glucose burned, unless you quote it as ? kJ/ mole.
thank you that helps :)
To calculate the amount of energy released from the carbon-carbon single bonds when glucose is burned, you need to use the concept of bond energy. Bond energy is the energy required to break a specific type of chemical bond.
Step 1: First, you need to determine the number of carbon-carbon single bonds in glucose (C6H12O6). In glucose, there are several carbon-carbon single bonds, specifically six carbon-carbon bonds.
Step 2: Find the bond energy value for a carbon-carbon single bond. The bond energy for a carbon-carbon single bond is approximately 348 kilojoules per mole (kJ/mol).
Step 3: Multiply the number of carbon-carbon single bonds by the bond energy value. In this case, multiply 6 carbon-carbon single bonds by 348 kJ/mol.
6 carbon-carbon single bonds * 348 kJ/mol = 2088 kJ (rounded to nearest whole number)
Therefore, approximately 2088 kilojoules of energy are released from the carbon-carbon single bonds when glucose is burned.
Remember, this calculation provides an estimation based on the average bond energy values. In reality, the energy released during combustion also depends on various other factors, such as reaction conditions and other bonds involved.
