Balancing Chemical Equations

The video tutorial demonstrates how to balance the chemical equation for H2CO3 plus NaOH. It begins by counting the atoms on both sides of the equation, focusing on hydrogen, carbon, oxygen, and sodium. The tutorial then proceeds to balance sodium by adjusting the coefficients and updates the oxygen count accordingly. Finally, it balances the hydrogen atoms, ensuring the equation is balanced. The video concludes with a confirmation that the equation is balanced and a thank you from Dr. B.
