  • I am getting decent at these,except the last one which is why I must practice!

    Why do we occassionally see

    H2 + 1/2 O2 ---> H20

  • It is common practice to multiply such things through by 2 so that all of the coefficients are integers. However, it's not a requirement, and sometimes it's handy to have fractional coefficients. For example, you might want to calculate the enthalpy change for a reaction 'per mole of H2', where this version would be most appropriate, or multiply through by 2 to calculate the enthalpy change 'per mole of O2'.
