What happens to mass during a chemical change?
Mass is conserved. This means it remains constant.
What is a chemical change and give example?
During a chemical change the molecules of reactants are transformed in molecules of products.Example: burning of methane gas in a burner.
Why is there no chemical equation to describe what happens when water evaporates?
That's because there is no chemical change. In most cases, there is no chemical change when a substance evaporates. The exception is very long molecules, which may break apart during evaporation.
When an electric currents is passed through water during the process of electrolysis?
It is a chemical change which manifests a physical effect of gas being evolved from a liquid. If the gases already existed and were just coming out of solution, it would be a physical change, but since it is a change from water molecules to oxygen and hydrogen molecules it is definitely a chemical change, not a physical one.
Why isn't a change in mass an indicator of chemical change?
A change in mass is not always an indicator of a chemical change because mass is conserved in chemical reactions. The total mass of the reactants is equal to the total mass of the products. However, there are some exceptions where a change in mass can occur due to the release or absorption of gases or changes in the physical state (such as evaporation or condensation) during a chemical reaction.
What happens to mass during a chemical change?
Mass is conserved. This means it remains constant.
What is conserved during any change color volume identity or mass?
The answer is mass. The Law of Conservation of Mass states that when a chemical or physical change takes place, you end up with the same amount of mass that you started in. It may just be in a different state, such as a gas.
What are the differences betwen physical and chemical changes in terms of what happenes to molecules?
During a chemical change the molecule is transformed; during a physical change the molecule is not transformed.
What happens to matter and energy during a chemical reaction?
Conserved.
What happens to the total mass of substances during a chemical reaction?
During a chemical change,chemical energy may be changed to other forms of energy.other forms of energy may also be changed to a chemical energy.
Why is mass conserved during the combution of methane?
Its conserved during the combustion of anything - the mass of the products is always equal to the mass of the materials that react.
What is a chemical change and give example?
During a chemical change the molecules of reactants are transformed in molecules of products.Example: burning of methane gas in a burner.
What type of change occurs in a chemical reaction?
a precipitate is a solid that forms during a chemical reactions
What is conserved when one balances a chemical equation?
Mass (Matter) and Energy is conserved during a Chemical equation
When carbon dioxide in air converts to more complex molecules by plants during photosynthesis is that a physical change?
chemical
What undergo no chemical change during a chemical change?
Catalysts doesn't undergo a chemical change during a chemical reaction.
Why is there no chemical equation to describe what happens when water evaporates?
That's because there is no chemical change. In most cases, there is no chemical change when a substance evaporates. The exception is very long molecules, which may break apart during evaporation.
