Examples of chemical changes in the nature?
Examples of chemical changes in nature include wood burning in a forest fire, photosynthesis, the formation of sulfuric acid in volcanic vents, and the fixing of nitrogen in lightning bolts and bacteria.
Describe the sequence of energy changes beginning with the sun and ending with burning wood for a campfire?
See, I don't exactly know if this is correct or not. The suns energy is mechanical energy and it shines down on some wood and starts heating it up. the wood starts burning and that is chemical energy. Check with someone else to make sure it is correct.
If you chop wood for a fire and then burn the wood you have made both physical and chemical changes.?
Yes, chopping is a physical change: the chemical composition of the molecules inside the wood remains the same. Burning causes the molecules in the wood to react with the air (mostly with the oxygen in the air), and the result is different compounds than before.
When you burn wood in a campfire what energy is change?
Burning wood is an example of chemical energy changing into heat and light energy. Energy is not destroyed, it simply changes from one form to another.
Is burning of wood an example of an oxidation reduction reaction?
Burning Wood is similiar to Volcanic Ash
What are several ways that burning changes the nature of wood?
Burning is an oxidation (reaction with oxygen): wood is an organic material and easily burn. The final products are water, carbon dioxide and ash.
What are the ways that burning changes the nature of wood?
Burning causes a physical and chemical change to wood. The physical change comes from the cellulose in the cell walls undergoing incomplete combustion and leaving behind ash and charred residue. The chemical changes that occur happen when the organics undergo complete combustion and turn into carbon dioxide and water vapor.

Is burning wood sublimation?
Burning wood does not involve sublimation. Sublimation changes a solid to a gas without altering it chemically. Wood burning does involve destructive distillation. The wood is chemically destroyed, and parts of it go off as gasses, which then combust.

The burning of wood creates what kind of energy?
Energy cannot be created. (Or destroyed) Burning changes the chemical energy of the wood to heat energy and light energy.
Ways that burning changes the nature of wood?
heat change in shape change in size change is texture, I think those are right anwser
What are the example of chemical changes?
burning of wood evaporating salt water cocout water turning into vinegar
Is a burning wood into ashes and smoke a physical or chemical change?
Burning wood is a chemical change - although, like most chemical changes it is accompanied by a physical change. Usually we reserve the term physical changes for things like erosion, melting, or evaporation where no change in composition occurs.
What is an example of a chemical change wood burning glass breaking water freezing?
The chemical change is the burning wood because the products, carbon dioxide, water, ash, and soot, have different physical and chemical properties. The other changes are physical changes because the physical and chemical properties of the substances did not change.
Is wood burning an example of combustion?
Yes, wood burning is an example of combustion.
When wood is burned heat ash and smoke are produced describe this reaction and explain what type of change is occurring?
The reaction of the wood burning is Oxidation as wood combines with air, the type of change that is occurring is a chemical change.
