Questions and Answers
What is the principle of conservation of mass in science?
The principle of conservation of mass states that mass cannot be created or destroyed in a chemical reaction. The total mass of the reactants must be equal to the total mass of the products.
Why is the conservation of mass important in scientific investigations?
The conservation of mass is important in scientific investigations because it allows scientists to accurately analyze and predict the outcomes of chemical reactions. It helps in understanding the quantity of substances involved in a reaction and ensures that mass is conserved throughout the process.
Give an example of a chemical reaction that demonstrates the conservation of mass.
One example of a chemical reaction that demonstrates the conservation of mass is the combustion of methane (CH4) in oxygen (O2) to produce carbon dioxide (CO2) and water (H2O). The total mass of the reactants (methane and oxygen) is equal to the total mass of the products (carbon dioxide and water).
