Why do ashes weigh less than paper?

Why do ashes weigh less than paper?

Combustion. For example, when paper is burned oxygen from the air combines with carbon and hydrogen in the paper turning some of it into carbon dioxide and water vapor, which waft away with carbon particulates in the smoke. This, not surprisingly, leaves the solid ash leftover lighter than the original paper.

When you burn a piece of paper is there more or less mass?

You are left with less mass because the cellulose in the paper combines with the atmospheric oxygen in the burning reaction. As output we get heat, carbon dioxide, carbon monoxide, some water and stuff that does not burn. The water and the gases leave and you are left with the ashes.

Would you expect the mass of the ashes to be the same as the mass of the paper before it was burned?

It may seem as though burning destroys matter, but the same amount, or mass, of matter still exists after a campfire as before. The mass of matter is always the same before and after the changes occur.

How much mass does Ash have?

About 5 pounds for an adult. The weight can vary from 3 pounds all the way up to 10, depending on the size and density of the deceased’s bones. Organ tissue, fat, and fluids burn away during cremation, leaving only bone behind when the incineration’s completed.

Do ashes weigh the same?

Weight of Ashes After Cremation As a general rule, ashes following cremation will weigh between 4 to 6 pounds, or around 3.5% of the person’s original weight. In the case of children, ashes weigh about 2.5% of the original body weight.

Why can’t you recognize the piece of paper anymore after it has burned?

A chemical reaction is when the substance is chemically change. a chemical reaction also can’t be reversed. When paper is burn, the cellulose in the air reacts with the oxygen to form carbon dioxide and water. Also, the action of burning paper can’t be reversed.

What is paper ash made of?

What Is The Composition Of Paper Ash? The primary chemical component of paper ash is carbon with varying amounts of elements such as Magnesium, Calcium, Potassium, and Phosphorus. However, if your paper had ink and incense, it’s most likely that it contains other chemicals, making it toxic for your plants.

Why can we not change the ash into original piece of paper?

When a paper is burnt, the molecules of paper undergo change forming new substances like smoke and water vapour. The change here is irreversible. So, a burnt piece of paper cannot be brought back to its original form.

When a log completely burns in a campfire the mass of the ash is much less than the mass of the log what happens to the matter that composed the log?

Terms in this set (7) When a log completely burns in a campfire, the mass of the ash is much less than the mass of the log. What happens to the matter that composed the log? The matter that composed the log reacts to form gases that are released into the air.

How is the ash produced by burning paper different from the original paper?

The ash produced by the burning paper has much less mass than the mass of the original paper. Was – Brainly.com The ash produced by the burning paper has much less mass than the mass of the original paper.

What happens to the ash when it is burned?

When paper is burned, the mass of the remaining ash is less than the mass of the original paper. Which statement best explains this result? The ash has less volume than the paper. Some of the matter is destroyed during the reaction. The mass of the ash cannot be accurately determined.

Why does paper have a lighter mass than smoke?

When paper burns, oxygen from the air combines with carbon and hydrogen from the paper in a chemical reaction to produce CO2 and water vapour. These waft away after the burning, just like smoke. Therefore, the paper has a lighter mass, because some of the mass it held before (from the carbon and hydrogen) has been lost.

What happens to the mass of paper when it burns?

Mass was not conserved during this change. When paper burns, oxygen from the air combines with carbon and hydrogen from the paper in a chemical reaction to produce CO2 and water vapour. These waft away after the burning, just like smoke.
