What is incorrect about the law of conservation of mass?

It can be stated as: “Mass can neither be created nor destroyed during a physical or a chemical change”. A given compound always contains exactly the same proportion of elements by weight can be explained by Law of Constant Proportion. Hence this is an incorrect statement about the Law of Conservation of Mass.

What is the law of conservation of mass simplified?

The law of conservation of mass is a fundamental principle of physics. According to this law, matter can be neither created nor destroyed. In other words, the mass of an object or collection of objects never changes, no matter how the parts are rearranged.

What is the law of conservation of mass explain with the help of example?

The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted.

Why is matter neither created nor destroyed?

Both the initial and final substances are composed of atoms because all matter is composed of atoms. According to the law of conservation of matter, matter is neither created nor destroyed, so we must have the same number and type of atoms after the chemical change as were present before the chemical change.

What is the law of conservation of mass Class 9?

The law states that mass can neither be created nor destroyed in a chemical reaction i.e. Total masses of reactants is equal to the sum of masses of products and the masses of unreacted reactants.

What is law of conservation of mass explain with an example class 9?

Law of conservation of mass states that mass can neither be created nor destroyed in a chemical reaction. So, the sum of the masses of the reactants and products remains unchanged. For example: CaCO3→CaO+CO2. 100 g 56 g 44 g.

What can be created but not destroyed?

The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. In other words, energy cannot be created or destroyed.

Where did the lost mass go as mass is not created or destroyed?

When hydrogen atoms fuse to form a helium atom, a tiny fraction of mass is lost. The lost mass is converted into the massive amount of energy we experience as sunlight. Even this mass isn’t destroyed, but it is converted into energy.

What types of changes observe the law of conservation of mass?

The Law of Conservation of Mass Matter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.
