Balancing Chemical Equations Steps

The video tutorial demonstrates how to balance the chemical equation for potassium iodide and bromine gas. It begins by counting the atoms on both sides of the equation, then proceeds to balance iodine by adjusting coefficients. Next, it balances potassium and bromine, ensuring the equation is fully balanced. The tutorial concludes with a summary of the balanced equation.

What is the initial number of iodine atoms on the reactant side of the equation?

• One

• Two

• Three

• Four

How do you balance the iodine atoms in the equation?

• Add a coefficient of 3 in front of KI

• Add a coefficient of 2 in front of KI

• Add a coefficient of 2 in front of Br2

• Add a coefficient of 3 in front of Br2

What is the effect of placing a coefficient of 2 in front of KI?

• It balances the bromine atoms

• It balances the entire equation

• It balances the potassium atoms

• It balances the iodine atoms

What is the next step after balancing iodine atoms?

• Balance the oxygen atoms

• Balance the potassium atoms

• Balance the hydrogen atoms

• Balance the nitrogen atoms

What is the final step to ensure the equation is balanced?

• Add a coefficient of 4 in front of KBr

• Add a coefficient of 1 in front of KBr

• Add a coefficient of 2 in front of KBr

• Add a coefficient of 3 in front of KBr
