Burning Wood is similiar to Volcanic Ash
yes
True
Oxidation.Rust is an example of an oxidation reaction between iron and oxygen. This is why a coat of oil on iron-containing metal prevents rust--the oil stops oxygen from reaching the metal's surface so that the oxidation reaction cannot take place.
Burning of paper is an oxidation reaction.
It's not entirely clear what the question is asking... but oxidation involves the loss of electrons from an atom or ion, and reduction involves the gain of electrons. The other parts of a redox (reduction-oxidation) reaction may involve atoms forming and breaking bonds, but the oxidation or reduction part is just about losing or gaining electrons. You might be talking about what is called a "half-reaction." A half-reaction is the part of the reaction that is only either the oxidation step or the reduction step. Neither is a complete reaction, but put together the two half-reactions give the overall reactions. In the oxidation half-reaction, electrons come out as products, and in the reduction half-reaction electrons go in as reactants. Remember: OIL RIG Oxidation Is Loss; Reduction Is Gain.
When the oxidation states of reactants in a chemical reaction are changed (parallel phenomena of oxidation and reduction) a redox reaction occur:Fe2O3 + 2 Al = Al2O3 + 2 Fe
True
When tarnish forms on silver
Both oxidation and reduction

An example of elimination reaction is seen in the reaction of isobutylbromide with potassium ethoxide in ethanol. Isobutylene, ethanol and potassium bromide is the resulting reaction.

It is an example of chemical change which cannot be reversed. In this change, Iron oxidizes under the presence of oxygen and moisture. The reaction is called a reduction-oxidation, or redox, reaction.
Candle burning is the process called oxidation. This is, it's the reaction that takes place when a gaseous material reacts with oxygen, the wax needs to change to gaseous state for the reaction to take place.
burning is a good example
