Why do ashes weigh less than the log?

Because much of the carbon and H2O components of the wood have dispersed, the weight of the remaining matter is much lower than the original log. In other words, most of it went up in smoke.

When wood is burned the ashes weigh less than the original wood so this is a violation of the law of conservation of mass?

As observed in the reaction above, the total mass of elements is same on both sides of the equation. After the reaction, wood burns to give carbon dioxide and water (gaseous) and ash. Hence the law of conservation of energy still holds, except that the state of the compounds has changed.

Why do logs have more mass than the ashes that result after they’re burned?

The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant.

When a log burns the resulting ash obviously has less mass than the log did explain whether this loss of mass violates the law of conservation of mass?

So, in other words, mass cannot be created nor destroyed. In a burning log, the initial mass of the wood and the ashes that are left behind after it burns are different, which would seem to violate the law of conservation of mass.

Why is burnt wood lighter?

Oxygen from the air is combining with carbon in the wood to form carbon dioxide. If this counts as smoke, then the smoke weighs more than the wood because it includes the weight of the oxygen. If smoke is just the particulate stuff you can see, then it weighs much less.

When wood burns a small amount of ashes is made Why is the mass of the wood before the fire not equal to the mass of the ashes after the reaction?

When wood burns, a small amount of ashes is made. Why is the mass of the wood before the fire not equal to the mass of the ashes after the reaction? The mass of the wood and the oxygen that allowed it to burn will equal the mass of the ashes and the gas given off during the burning.

When a log is burned the mass of the remaining ash is less than the mass of the original log Which statement best explains this result?

Unit 3 Lesson 2 Chemical Equations | Science Quiz – Quizizz. 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.

Does wood get heavier when burned?

No, its mass does not get destroyed. In fact, since burning involves combining the chemicals in the wood with oxygen from the air, the weight of all the products will be substantially greater than the mass of the original log.

Why do logs turn into ashes?

Ash is the residue left after a fire has consumed all the organic (carbon- based) materials. Wood is composed mostly of cellulose and lignin. When completely burned, these compounds are oxidized to carbon dioxide and water, both of which leave the fire as gases. These inorganic compounds compose the ash.

When a log burns in a fire what happens?

Log burning in a fire. Burning wood is an example of a chemical reaction in which wood in the presence of heat and oxygen is transformed into carbon dioxide, water vapour, and ash.

When paper is burned the mass of the remaining ash is less than the mass of the original paper Which statement best explains this?
