Example of Counting Atoms

For a clearer understanding, here is an example with the first equation:

Example Equation:

[ 2H_2 + O_2 \rightarrow 2H_2O ]

• Reactants:

  • H: ( 2 \times 2 = 4 ) (since there are 2 molecules of ( H_2 ))
  • O: ( 2 ) (since there is 1 molecule of ( O_2 ))

• Products:

  • H: ( 2 \times 2 = 4 ) (since there are 2 molecules of ( H_2O ))
  • O: ( 2 ) (since there are 2 oxygen atoms in 2 water molecules)

Totals:

Element	Reactants (left side)	Products (right side)	Total
H	4	4
O	2	2

Conclusion

Fill in the tables for each equation by counting the atoms carefully. This exercise will help reinforce your understanding of balancing chemical equations and familiarize you with the concept of conservation of mass in chemical reactions. Happy counting!
