A chemical reaction is a process in which one or more substances, also called reactants, are converted to one or more different substances, known as products. Substances are either chemical elements or compounds.

Q. What kind of reaction is a/b c?
7.10: Classifying Chemical Reactions
Name of Reaction | General Form |
---|---|
Exchange: Single Replacement | AB + C → AC + B |
Exchange: Double Replacement | AB + CD → AD + CB |
Combination (Synthesis) | A + B → AB |
Decomposition | AB → A + B |
Q. What does a combustion reaction look like?
Combustion reactions are common and very important. Combustion means burning, usually in oxygen but sometimes with other oxidants such as fluorine. A combustion reaction happens quickly, producing heat, and usually light and fire.
Q. How do you know if its a double replacement reaction?
The easiest way to identify a double displacement reaction is to check to see whether or not the cations exchanged anions with each other. Another clue, if the states of matter are cited, is to look for aqueous reactants and the formation of one solid product (since the reaction typically generates a precipitate).
Q. What is the main source of energy for carrying out decomposition reaction?
Most decomposition reactions require an input of energy in the form of heat, light, or electricity.
Q. What are decomposers reaction give three examples where heat light and electricity is involved?
1) calcium carbonate decomposes in calcium oxide & carbon dioxide when heated. 2)When heated strongly potassium chlorate decomposes into potassium chlorite and oxygen. 1) silver chloride decomposes into silver and chlorine . 2) hydrogen peroxide decomposes into water and oxygen.
Q. What are called thermolysis reaction?
Definition. Thermolysis is chemical decomposition by heating. If a reaction is endothermic, heat is required for the reaction to proceed. The term pyrolysis is often used in place of thermolysis when organic compounds are decomposed at high temperature.
Q. What is thermal decomposition explain with example?
A thermal decomposition reaction occurs when heat is applied to a compound causing it to decompose (break down) into multiple different chemical substances. An example is when baking soda (sodium bicarbonate) is heated. 2NaHCO3(s)→CO2(g)+H2O(g)+Na2CO3(s)
Q. What is an electrolysis reaction?
Electrolysis, process by which electric current is passed through a substance to effect a chemical change. The chemical change is one in which the substance loses or gains an electron (oxidation or reduction).
