# What is conservation of mass in simple terms?

## What is conservation of mass in simple terms?

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 is an example of conservation of mass?

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 conversion of mass important?

According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants. The law of conservation of mass is useful for a number of calculations and can be used to solve for unknown masses, such the amount of gas consumed or produced during a reaction.

### Can matter be destroyed for kids?

Matter never vanishes. Matter is anything that has weight and takes up space. Anything you can see and touch is matter. Remember, matter has three main forms: solid, liquid, and gas.

### Is mass conserved when wood or paper burns?

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. So the mass of the product equals the mass of the reactant.

Is law of conservation of mass always valid?

The fundamental conservation law of the universe is the conservation of mass-energy. Mass is therefore never conserved because a little of it turns into energy (or a little energy turns into mass) in every reaction. But mass+energy is always conserved. Energy cannot be created out of nothing.

#### What violates the law of conservation of mass?

Nuclear reactions appear to violate both the Laws of Conservation of Mass and Energy because mass is converted into energy or vice versa.

#### How does this experiment demonstrate the law of conservation of mass?

Given Alka-Seltzer and a flask, students design and conduct an experiment to prove the Law of Conservation of Mass. The law of conservation of mass indicates that mass cannot be created nor destroyed. This means the total mass of reactants in a chemical reaction will equal the total mass of the products.

Can you destroy matter?

Matter can neither be created nor destroyed. This is the law of conservation of matter (mass). The amount of water (matter) stayed the same, but the volume just changed a bit.
