Balancing Chemical Reactions of Methane

The video tutorial explains the process of balancing a chemical equation involving methane (CH4) and chlorine gas (Cl2) to produce dichloromethane (CH2Cl2) and hydrochloric acid (HCl). It begins by introducing the reactants and products, followed by counting the atoms of each element. The tutorial then demonstrates how to balance the hydrogen atoms by adjusting coefficients and proceeds to balance the chlorine atoms. The video concludes with the final balanced equation and a brief summary.

What are the products formed when methane reacts with chlorine gas?

• Methanol and chlorine gas

• Two

• Three

• Four

What is the initial imbalance in the number of chlorine atoms between the reactants and products?

• One chlorine atom

• Two chlorine atoms

• Three chlorine atoms

• Four chlorine atoms

What coefficient is placed in front of HCl to balance the hydrogen atoms?

• 2

• 1

• 4

• 3

After balancing hydrogen atoms, how many hydrogen atoms are there in total in the products?

• Two

• Three

• Four

• Five

What coefficient is used to balance the chlorine atoms in the equation?

• 1

• 2

• 3

• 4

What is the final balanced chemical equation for the reaction between methane and chlorine gas?

• CH4 + Cl2 → CH2Cl2 + HCl

• CH4 + 2Cl2 → CH2Cl2 + 2HCl
