Question

Find the number of atoms
C5H12 + 6O2 ---> 6CO2 + H2O

Answer 1

The balanced chemical equation is:

C5H12 + 6O2 ---> 5CO2 + 6H2O

From this equation, we can see that for every one molecule of C5H12 that reacts, we get 5 molecules of CO2 and 6 molecules of H2O.

To find the number of atoms involved, we need to look at the number of atoms in each molecule.

One molecule of C5H12 contains:
- 5 carbon atoms
- 12 hydrogen atoms

One molecule of CO2 contains:
- 1 carbon atom
- 2 oxygen atoms

One molecule of H2O contains:
- 2 hydrogen atoms
- 1 oxygen atom

Using this information, we can calculate the total number of atoms present:

5 (C atoms) + 12 (H atoms) + 6 (O2 molecules x 2 O atoms per molecule) = 5C + 12H + 12O = 29 atoms

So, there are 29 atoms involved in the reaction.
