What does the Law of Conservation of Mass state?

Back

The Law of Conservation of Mass states that mass is neither created nor destroyed in a chemical reaction; the total mass of reactants equals the total mass of products.

How do you identify the products of a combustion reaction?

Back

In a combustion reaction, the products are typically carbon dioxide (CO2) and water (H2O) when hydrocarbons react with oxygen.

What is the balanced equation for the combustion of ethylene (C2H4)?

Back

C2H4 + 3O2 → 2CO2 + 2H2O.

What is the significance of balancing chemical equations?

Back

Balancing chemical equations ensures that the Law of Conservation of Mass is upheld, showing that the number of atoms for each element is the same on both sides.

Front

What is the role of coefficients in a chemical equation?

Back

Coefficients indicate the number of moles of each substance involved in the reaction and are used to balance the equation.
