Question

state and prove the law of conservation.of mass

Answer 1

The law of conservation of mass states that when you perform some process, the weight of what you make will be identical to the weight of what you started with. For example, if you melt an ice cube, the weight of the water will be identical to the weight of the ice.

As far as proving this, you really can't. You can disprove things just fine using science, but you can never really prove that anything is 100% always the case. You never know if something will come along to throw you off.

In the case of the law of conservation of mass, it turns out that, strictly speaking, it's not true. In nuclear reactions, very small amounts of mass are lost due to the conversion of mass to energy using Einstein's equation e = mc2. For this reason, it's more correct to call this the law of conservation of mass-energy.

OK.

gives the reasons and includes Lavoisier experiment on this page: https://www.chem.wisc.edu/deptfiles/genchem/sstutorial/Text1/Tx14/tx14.html

Answer 2

law of conservation of mass is given by Antony leavisser ..


according to this llamas neither be created nor be destroyed in a chemical reaction..


for example

$mg +02 = 2mgo$
hopes it will be helps!!!
