A catalyst.
A substance that cannot be broken down any further and stays the same substance would be an element
In physical changes, the amount of mass stays the same because no new substances are formed. In chemical changes, the amount of mass stays the same due to the law of conservation of mass, which states that mass cannot be created or destroyed, only rearranged into different substances.
Temperature remains constant
A staircase.
No, a decomposition reaction is the opposite of a synthesis reaction. In a decomposition reaction, a compound breaks down into simpler substances, while in a synthesis reaction, simpler substances combine to form a more complex compound.
No. The flour stays chemically the same. Sifting mixes air with the flour and breaks up lumps.
the same way yours breaks down~ WITH THERE STOMACH ACID
A controlled variable means that it stays the same while other substances change. This helps prove the exact changes in an experiment.
Heating gasses or liquids has no effect on their masses.
The dissolving of sodium hydroxide in water is a physical change because no new substances are formed. Sodium hydroxide breaks down into its ions in the water, but its chemical composition remains the same.
A variable in an experiment that stays the same is a constant.
No, deposition is not the process that breaks down granite into sediment. The process that breaks down granite into sediment is called weathering, which can be caused by physical, chemical, or biological factors. Deposition refers to the laying down or settling of eroded material in a new location.
