What evidence of a chemical reaction might you see when burning a match?
Volatile compounds in the wood undergo combustion, or reaction with oxygen, forming H20 and CO2 gases. Because of the makeup of wood being mostly carbon-based compounds, this reaction leaves behind soot and charcoal.
What might be formed in the chemical reaction H202?
H2O2 is not a chemical reaction, it is Hydrogen Peroxide.
What kind of reaction is also commonly called 'burning'?
Another name for burning is combustion. The term combustion is more commonly used in scientific fields like chemistry and physics.
What simple test might be undertaken to check if a chemical reaction produces oxygen?
glowing splint ... if it relights then the chemical reaction produces oxygen.
Is burning wood a chemical or physical change'?
It is a chemical change as you are altering the chemical structure of the wood.Burning wood is a chemical change. Although some might be confused on whether or not it is a chemical change it definitely is chemical change because when you burn wood, or mostly anything actually, a carbon dioxide gas is released into the air. As most might know a chemical change is when some type of substance reacts with another when in contact and it produces a new substance. In this case burning wood was created off of the burning chemicals in the wood, thus the carbon dioxide gas was released and exposed into the air.its chemical change definitely chemical changedefinite.It can be both actually because if you start a fire your self and do it or if it is a wild fire. :)its really physical.Chemical--new compounds are created. Example: glucose becoming water and carbon dioxide.Chemical change. Components in the wood combine with oxygen, releasing heat.chemical change;because once you have burnt it you cant make it a piece of wood again.Burning wood is a chemical change.its a chemical change, because you can not reverse itChemicalThe burning of wood is the oxidation of wood by combustion.Oxidation is a chemical reaction where (usually) oxygen reacts with a chemical to form other chemicals and gives off heat (an exothermic reaction).So the burning of wood is a chemical change. The resultant chemicals, (ash/soot/water/CO2...depending on the completeness of the reaction) are physically different to the wood, but the change is much more than physical.No, it is a chemical changeBurning wood is a chemical change.Burning wood is a chemical change because the reaction is not reversable and the end product is two separate chemicals.Burning wood is a chemical change because you are altering the CHEMICAL structure of the wood.it is chemical changeCombustion is a chemical process involving the oxidation. Burning wood is an example of this.ChemicalA chemical change. The composition is being changed and mass is lostChange of state from wood to ash can be described as physical change and burning of wood is through coming in contact with oxygen and hence it is both physical and chemical change.it is a physical changeA chemical change. The substances present before burning are altered to something else by the end of the burning.
What evidence of a chemical reaction might you see by rusting of an iron nail?
oxidation
What might release energy during a chemical reaction?
a cake anything cooked
Do catalyst produce chemical reactions?
yes chemical reactions in order to induce a chemical reaction that might normally take a long time
What type of chemical reaction is this caCO3 CaO CO2?
Decomposition Reaction
What from of energy might be needed for a chemical reaction to take place?
heat & electric energy !
What evidence of a chemical reaction might you see by dropping an alka seltzer in water?
its a chemical reaction becase once the alka seltzer melts you cant take it out and put it back together
How do you turn a chemical reaction into a physical reaction?
A good example might be a steam locomotive. It starts with a chemical reaction, where carbon combines with oxygen in the firebox. This heats water to generate steam which drives the cylinders, which turn the wheels and make the locomotive move...a physical reaction. Or a gun, where a chemical reaction, the decomposition of a propellant creates gas which propels a bullet.
