Question
Determine the number of atoms
C5H12 + 6O2 ---> 6CO2 + H2O
C5H12 + 6O2 ---> 6CO2 + H2O
Answers
To determine the total number of atoms in this balanced chemical equation, we need to count the atoms in each molecule on both sides of the equation.
C5H12: 5 carbon atoms and 12 hydrogen atoms (total of 5+12 = 17 atoms)
6O2: 6 * 2 = 12 oxygen atoms (total of 12 atoms)
6CO2: 6 * (1 carbon atom + 2 oxygen atoms) = 6*(1+2) = 6*3 = 18 atoms
H2O: 2 hydrogen atoms and 1 oxygen atom (total of 2+1 = 3 atoms)
Now, add up all the atoms:
Reactants (left side): 17 (C5H12) + 12 (6O2) = 29 atoms
Products (right side): 18 (6CO2) + 3 (H2O) = 21 atoms
Since the balanced chemical equation has equal numbers of each type of atom on both sides, the total number of atoms on both sides should be the same, which is 29 atoms.
