What else can I help you with?
Type of change that happens when you break a rock or freeze water?
Physical change: breaking a rock changes its physical appearance without altering its chemical composition. Freezing water involves a physical change where the water molecules rearrange to form a solid structure, without any change in the chemical composition of water.
What kind of chemical compound do salt in water form?
When salt is mixed in with water, they form a solution. Salt is the solute, and water is the solvent.
What happens to atoms and molecules when a chemical change occurs?
They get rearranged to form new products.
When a cube of ice melts to form a puddle of water is it a physical or chemical change?
The melting of ice to form water is a physical change. It involves a change in state from solid to liquid, but the chemical composition of the substance remains the same.
Suger cube dissolves in water is it chemical or physical change?
The dissolving of a sugar cube in water is a physical change, not a chemical change. This is because the sugar molecules are still present in the water; they have not undergone a chemical reaction to form new substances.
What type of change had to happens for elements to form water?
A chemical reaction/bond.
What kind of change happens when hydrogen gas and oxygen gas react burn and form water?
This reaction is a chemical change.
Is Oxygen and hydrogen combining to form water physical or chemical change?
This is a chemical change.

What is the name of a chemical reaction that happens when chemicals change to a new form?
substance
What kind of chemical compound do salt in water form?
When salt is mixed in with water, they form a solution. Salt is the solute, and water is the solvent.
Is it a physical property or chemical property if it reacts with a base to form water?
It is a chemical property. When a substance reacts with a base to form water, it undergoes a chemical change, illustrating its chemical reactivity.
What happens to atoms and molecules when a chemical change occurs?
They get rearranged to form new products.
Is cooling liquid water to form ice a chemical change?
No. Freezing is a physical change.
When a cube of ice melts to form a puddle of water is it a physical or chemical change?
The melting of ice to form water is a physical change. It involves a change in state from solid to liquid, but the chemical composition of the substance remains the same.
Is water freezing at zero degrees Celsius physical or chemical change?
Water freezing at zero degrees Celsius is a physical change. This is because the change in temperature causes the water molecules to slow down and form a solid structure, without altering the chemical composition of water.
Suger cube dissolves in water is it chemical or physical change?
The dissolving of a sugar cube in water is a physical change, not a chemical change. This is because the sugar molecules are still present in the water; they have not undergone a chemical reaction to form new substances.
