Balancing Chemical Equations

The video tutorial explains how to balance the chemical equation LiH + H2O. It begins by counting the atoms on both the reactant and product sides, ensuring that the number of each type of atom is equal on both sides. The tutorial highlights common mistakes, such as forgetting to count certain hydrogen atoms, and concludes by confirming that the equation is balanced. Dr. B provides a clear and concise explanation, making it easier for viewers to understand the process of balancing chemical equations.

What is the first step in balancing the equation LiH + H2O?

• Change the coefficients randomly

• Count the number of electrons

• Count the number of atoms on each side

• Add more reactants

How many hydrogen atoms are there in total on the reactant side of the equation?

• Four

• Two

• One

• Three

What is the total number of oxygen atoms on the product side?

• Three

• One

• Zero

• Two

What common mistake might lead to an incorrect balance of the equation?

• Counting lithium atoms twice

• Forgetting to count all hydrogen atoms

• Adding extra oxygen atoms

• Ignoring the coefficients

What is the balanced equation for the reaction between lithium hydride and water?

• LiH + H2O → LiO + H3

• LiH + H2O → LiH2O + H

• LiH + H2O → Li + H2O

• LiH + H2O → LiOH + H2
