The equation 10HNO3 + 3Ba -> 3Ba(NO3)2 + 5H2O + 10NO

  1. Detailed information about the equation 10HNO3 + 3Ba -> 3Ba(NO3)2 + 5H2O + 10NO:

    • The above chemical equation describes the reaction between nitric acid (HNO3) and Barium (Ba) to form barium nitrate (Ba(NO3)2), water (H2O), and Nitric Oxide (NO).
    • According to the balanced equation, every 10 moles of nitric acid will react with 3 moles of Barium to form 3 moles of barium nitrate, 5 moles of water and 10 moles of Nitric Oxide.

  2. Reaction conditions:

    • For the reaction to take place, nitric acid and barium need to be placed in a sufficiently humid reaction environment.
    • Temperature is also an important factor, the reaction will occur faster at higher temperatures.

  3. Reaction process:

    • DDuring the reaction process, nitric acid (HNO3) will act on Barium (Ba), causing the electron of Barium to move from its outer shell to the shell of the nitrate atom, forming a nitrate ion (NO3-) and a barium ion (Ba2+).
    • These ions then form the compound barium nitrate (Ba(NO3)2).
    • During this process, water and nitric oxide are also produced.

  4. Phenomena occurring:

    • When nitric acid (HNO3) reacts with Barium (Ba), a white solid of barium nitrate (Ba(NO3)2) is formed.
    • At the same time, nitric oxide (NO) gas and water vapor are released.
    • Another observable phenomenon is that the temperature of the reaction mixture will increase as this is an exothermic reaction.
