What type of reaction is dynamite exploding?
Low explosives (like black powder) rely on combustion to generate energy. Combustion is produced by the reaction of oxygen and some sort of fuel at high temperatures. As a result, the rate of a combustion reaction is limited both by the amount of fuel present and the amount of oxygen it comes in contact with.
Is vaporize a chemical change?
Explanation: It is a physical change because it is going from the liquid phase to the gas phase. It is not a chemical change because it is still made of two hydrogen atoms and an oxygen atom.
Is corrosion a chemical change?
Explanation: Chemical change is characterized by the formation of new substances and the making and breaking of chemical bonds. Corrosion is a chemical change.
Is explode a physical or chemical change?
The explosion of fireworks is an example of chemical change. During a chemical change, substances are changed into different substances. Another words, the composition of the substance changes.
Is combust a physical or chemical change?
combustion, a chemical reaction between substances, usually including oxygen and usually accompanied by the generation of heat and light in the form of flame.
Why is fireworks exploding a chemical change?
Fireworks are the result of chemical reactions involving a few key components — like a fuel source (often charcoal-based black powder), an oxidizer (compounds like nitrates, chlorates that produce oxygen) and a color-producing chemical mixture. The oxidizer breaks down the chemical bonds in the fuel, releasing energy.
