Who Gave Law Of Conservation Of Mass Class 9? Antoine LavoisierA portrait of Antoine Lavoisier, the scientist credited with the discovery of the law of conservation of mass. 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.
Why Do Atoms Combine In A Fixed Ratio By Weight? The reason atoms combine in whole number ratios is because of the way the atoms join to create a compound. When an atom has an incomplete valence (outer) shell of electrons, it will combine with other atoms in a way that completes that outer shell,
Why Definition Of Atom Given By Delton Is No Longer Valid? All the matter is made up of very small particle called atoms. Atoms can neither be created or nor destroyed. Why was Dalton’s model of the atom rejected? Answer: According to Dalton atoms of different elements combine in simple whole number ratio to form
What Are The Five Major Points Of Atomism? 1) elements are made of extremely small particles called atoms. 2) these elements will be identical in size, mass and other properties. 3) atoms cannot be destroyed or created. 4) atoms of different elements combine in simple whole number ratios to form chemical compound. What are 5
