Is making chalk dust a chemical change?
No, it is a physical, not chemical change.
When solid sulfur is broken down is it physical or chemical changes?
It is a physical change, the chemical form remain unchanged.
If a solid is crushed to a powder is it a physical or chemical change?
Crushing a solid to a powder is a physical change because the substance's chemical composition remains the same. The particles in the solid are just broken apart into smaller pieces without any chemical reactions taking place.
What reaction doesn't make a new substance?
A physical change, such as changing the state of matter (solid to liquid) or breaking an object into smaller pieces, does not produce a new substance. These changes involve only the physical properties of a substance, not its chemical composition.
Is melting of lead a chemical reaction?
No, melting of lead is a physical change, not a chemical reaction. A chemical reaction involves the breaking and forming of chemical bonds to create new substances, while melting only involves a change in state from solid to liquid with no change in chemical composition.
Is making chalk dust a chemical change?
No, it is a physical, not chemical change.
Is rock broken into small pieces a chemical change?
No actually it isn't. Breaking a bone is a physical change. Think about it. Are you changing it into a different substance. No you're not, so it's a physical change.
What does breaking up a solid reactant into finer pieces do to it in terms of how it reacts?
When breaking up a solid reactant into finer pieces, what will happen is that the rate of reaction will increase. This is really the only major change that will happen in terms of how it will react.
When solid sulfur is broken down is it physical or chemical changes?
It is a physical change, the chemical form remain unchanged.

Does the mass of a solid change or stays the same?
The mass of a solid remains the same as long as it is not altered through processes like physical changes (e.g., breaking it into smaller pieces) or chemical changes (e.g., burning it). Mass is a measure of the amount of matter in an object, and it is conserved in closed systems. Therefore, unless mass is added or removed, a solid's mass will stay constant.
What type of change occurs in a chemical reaction?
In a chemical reaction, a chemical change occurs where the chemical composition of the substances involved is altered, leading to the formation of new substances with different properties. This change involves the breaking and forming of chemical bonds.
