What is law of conservation of mass explain?
The law of conservation of mass states that in a chemical reaction mass is neither created nor destroyed. For example, the carbon atom in coal becomes carbon dioxide when it is burned. The carbon atom changes from a solid structure to a gas but its mass does not change.
What is law of conservation of mass short answer?
The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.
What is law of conservation of mass Class 8?
The ‘law of conservation of mass’ says that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. The mass of the products in a chemical reaction must equal the mass of the reactants.
Who gave the Law of Conservation of Mass?
Antoine Lavoisier’s
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 are some real life examples of the law of Conservation of mass?
A Real-Life Example. A typical scenario that involves the use of the Law of Conservation of Mass is melting of an ice cube of ten grams during a hot day. The ice cube would change its states from solid to liquid and finally become vapor.
Is the law of Conservation of mass always valid?
No, the law is not valid always. First of all, the law of conservation of mass is valid for closed and isolated system only because, in an open system some of the mass can be converted into energy and escapes the system and then the resultant will be different and the rule will be violated.
Can the law of Conservation of mass be violated?
Yes, the law of conservation of mass was violated in Part 1 because the experiment was not conducted like Part 2 which was sealed. The experiment was held in the open which allowed the mass to decrease when the baking soda and the vinegar started to react.
What is equation follows the law of Conservation of mass?
The law of conservation of mass can be expressed in terms of the equation if we consider a chemical reaction: A + B → C + D If X grams of A combines with Y grams of B in a chemical reaction to produce P grams of C and Q grams of D, the law of conservation of mass can be expressed as; X + Y = P + Q
