Your question isn't rigorous enough. When you burn coal you are combining carbon from the coal with oxygen in the air. So the mass of Carbon Dioxide created is greater than the original mass of coal. There is no mass destroyed however, you just have to be more rigorous in the parameters of your question.
What else can I help you with?
How could you set up an experiment to prove that burning a paper does not change its mass?
Weigh an empty non-flammable closed box and record its mass. Put a piece of paper with a large enough mass to be detected inside the closed box. Weigh the closed box with the paper inside it and record its mass. How do we -{Light the paper on fire inside the closed box and wait until the paper is fully burned}? Weigh the closed box with burned paper inside it and record its mass. Subtract the box with ashes weight from the box with paper weight, and analyze the result(s).
What would happen to density if the amount of sample increased?
If the amount of sample increased while the volume remained the same, the density would increase since the mass would be higher with the same volume. Density is calculated as mass divided by volume, so an increase in mass while keeping volume constant would result in higher density.
When substances go through a chemical change what happens to the mass'?
In a chemical change, the total mass of the substances involved before and after the reaction remains the same. This is known as the law of conservation of mass. This means that no atoms are created or destroyed during a chemical reaction.
What happens to the total mass of the carbon and oxygen after they form carbon dioxide?
The total mass of the carbon and oxygen remains the same before and after they form carbon dioxide. In a chemical reaction, mass is conserved, meaning that atoms are rearranged but not created or destroyed.
What Three Things Stay The Same Before And After A Chemical Reaction?
The number of atoms of each element participating in the reaction, the total mass of the substances involved, and the total charge of the reactants and products (law of conservation of mass and charge).
Does your mass increase decrease or stay the same if you so to Saturn?
Your mass will stay the same no matter where you go.
Does you mass always stay the same no matter what?
Yes, no gas is given off, therefore the mass of conversation will stay the same.
What would happen to your mass if you went to a planet with less gravity?
Your mass will stay the same. Mass is always the same no matter what.
After the water is boiled its mass stays the same yes or no?
After water has been boiled, its mass will stay the same.
If your mass is 68 kg on earth your mass on mars would be?
Your mass would stay the same. Mass is the amount of matter in an object, so your mass would stay at 68kg.
Does the mass of an object always stay the same?
Yes
What properties stay the same during physical and chemical change?
mass mass
When two properties of a crayon will stay about the same after the crayon is melted?
The two properties of a crayon that will stay about the same after being melted is it's color and mass.
When water evaporates why does the mass stay the same?
The law of mass conservation is generally valid.
How will the mass of a rocket change when it has reached outer space?
NO. the rocket will not shrink,grow,compact,or spread out and stay same size.the stuff in it will stay the same,,,,,,,,,,but the weight will change because there is no gravity to pull down on it. (The mass of the rocket will change continuously from the time it leaves the launch pad until sometime after it has reached space. That's because of the fuel mass it loses, as the engines burn. But once the engines cut off, the vehicle's mass doesn't change.)
Why does mass of an object stay the same on earth?
The mass of an object remains constant on Earth because mass is a measure of the amount of matter in an object, and this does not change based on the location or environment. Gravity affects weight, not mass, so an object's mass will stay the same regardless of where it is on Earth.
When Fe and CuS04 react does the mass stay the same?
Yes. See the Law of Conservation of Mass.
