State the law of conservation of matter? (2023)

State the law of conservation of matter?

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.

What is the law of conservation of matter answers?

The Law of Conservation of Matter says that the amount of matter stays the same, even when matter changes form. Sometimes it may seem that matter disappears during a science experiment, but this law tells us that matter cannot magically appear or disappear, it simply changes from one form to another.

Who described the law of conservation of matter and what does it state?

The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction.

What proves the law of conservation of matter?

All chemical reactions can demonstrate the law of conservation of matter. In some reactions, it will be easier to observe, however. For example, a good reaction is solid KI reacting with solid Hg(NO₃)₂ to form solid KNO₃ and solid HgI₂. The solids are easily massed and no gas produced that must be captured.
