Law of Conservation of Mass, Properties, and changes

Front

What is the Law of Conservation of Mass?

Back

The Law of Conservation of Mass states that mass is neither created nor destroyed in a chemical reaction. The total mass of the reactants equals the total mass of the products.

What is magnetism?

Back

Magnetism is a physical property that describes how a substance reacts to a magnetic field, either by being attracted or repelled.

Front

What is a chemical property?

Back

A chemical property is a characteristic of a substance that can only be observed during a chemical reaction, such as reactivity with other substances.

Front

What is a physical property?

Back

A physical property is a characteristic of a substance that can be observed or measured without changing the substance's identity, such as color, density, or melting point.

What does density determine about an object in water?

Back

Density determines whether an object will sink or float in water. If the density is less than 1 g/mL, it will float; if it is more, it will sink.

Front

What is a triple beam balance used for?

Back

A triple beam balance is a tool used to measure the mass of an object accurately.

Front

What is a physical change?

Back

A physical change is a change that affects one or more physical properties of a substance without altering its chemical composition, such as breaking glass.

Front

What is a chemical change?

Back

A chemical change is a change that results in the formation of new chemical substances, such as rusting iron or burning wood.

Front

What is solubility?

Back

Solubility is the ability of a substance to dissolve in a solvent, such as salt dissolving in water.

Front

What is malleability?

Back

Malleability is the ability of a substance to be deformed or shaped under pressure, such as metal being hammered into sheets.
