Question

What does the Law of Conservation of Mass state?
A) Matter cannot be gained or lost in a chemical reaction.
B) Matter can only be lost in a chemical reaction.
C) Matter can only be gained in a chemical reaction.
D) Matter can be gained and lost in A chemical reaction

Please answer with opposition ​

Answer 1

Answer:

This law states that, despite chemical reactions or physical transformations, mass is conserved — that is, it cannot be created or destroyed — within an isolated system. In other words, in a chemical reaction, the mass of the products will always be equal to the mass of the reactants.

Explanation:

Answer 2

Law of Conservation of Mass states A) Matter cannot be gained or lost in a chemical reaction.

• The Law of conservation of mass is also known as the Principle of Mass Conservation. This law holds for systems where the transfer of mass or energy is not occurring.
• In such a system, the mass will remain constant with respect to time.
• The mass can be converted to another form, but it will not be created or destroyed.
• Thus, the mass and number of elements on reactant side remain conserved or balanced on product side.
• The example of conservation of mass with a chemical reaction is - CH4 + 2O2 --> CO2 + 2H2O.
• In the above mentioned reaction, CH4 represents methane, O2 represents oxygen, CO2 represents carbon dioxide and H2O is chemical formula of water.
