What key feature must a chemical equation have for it to be classified as a combustion reaction?
A key feature of a combustion reaction is the reaction between a substance and oxygen to produce heat and light as products. In a combustion reaction, oxygen is typically a reactant, and the products formed are usually carbon dioxide and water.
Given the reaction fe s - fes energy which is true It is exothermic The potentialenergyof the reactantis the same as the product The potentialenergyofthereactcantislowerthanthe product endothermic?
The reaction Fe(s) → FeS(s) is exothermic because it releases energy. The potential energy of the reactant is higher than that of the product in an exothermic reaction.
Why a catalyst is not considered a reactant or product in a chemical reaction?
If a substance is a reactant or product of a chemical reaction then, by definition, it cannot be a catalyst.
Is light a product of combustion?
No, light is not a product of combustion. Light is typically produced when atoms or molecules release energy as photons, which can happen in a variety of processes such as electronic transitions in atoms or chemical reactions, not necessarily combustion. Combustion is a chemical reaction that releases heat and light as byproducts, but light itself is not a product of combustion.
Is a combustion reaction an endothermic reaction?
No, a combustion reaction is typically exothermic because it releases heat energy. Endothermic reactions absorb heat energy from the surroundings.
What key feature must a chemical equation have for it to be classified as a combustion reaction?
A key feature of a combustion reaction is the reaction between a substance and oxygen to produce heat and light as products. In a combustion reaction, oxygen is typically a reactant, and the products formed are usually carbon dioxide and water.
What is a true of a catalyst?
The catalyst is not a reactant in a chemical reaction but contribute to the success of this reaction.
What liquid is a product of a combustion reaction?
H20 and CO2 along with energy
is a reactant heat carbon dioxide or oxygen?
The reactant that absorbs heat in a combustion reaction is typically oxygen, not carbon dioxide. Oxygen acts as an oxidizing agent, combining with the fuel to release energy in the form of heat. Carbon dioxide is one of the products of the combustion reaction.
Is the sun reactant or a product?
The sun is neither a reactant nor a product in a chemical reaction. It is a source of energy that drives various chemical reactions on Earth through processes like photosynthesis and evaporation.
Given the reaction fe s - fes energy which is true It is exothermic The potentialenergyof the reactantis the same as the product The potentialenergyofthereactcantislowerthanthe product endothermic?
The reaction Fe(s) → FeS(s) is exothermic because it releases energy. The potential energy of the reactant is higher than that of the product in an exothermic reaction.
8. The ___ states that the TS‡ of a reaction resembles the structure of the species (i.e. reactant or product) to which it is closer in energy?
Organic Chemistry
What is product of combustion of ethanol?
The product of combustion of ethanol is carbon dioxide (CO2) and water vapor (H2O), along with heat energy released during the combustion process. This reaction is exothermic, meaning it releases energy as it proceeds.
Why a catalyst is not considered a reactant or product in a chemical reaction?
If a substance is a reactant or product of a chemical reaction then, by definition, it cannot be a catalyst.
Is 2SO2 plus O2 equals 2SO3 a combustion reaction Why or why not?
Yes, the reaction 2SO2 + O2 -> 2SO3 is a combustion reaction. This is because combustion reactions typically involve a fuel (SO2) reacting with oxygen (O2) to form a combustion product (SO3) with the release of heat and light energy.
What is a combustion reaction describe two ways in which you could increase the route of a combustion reaction?
A combustion reaction is a type of chemical reaction that involves the rapid combination of a fuel with oxygen, producing heat and light. Two ways to increase the rate of a combustion reaction are increasing the concentration of oxygen, which provides more reactant for the reaction, and increasing the temperature, which provides more kinetic energy to the molecules, leading to more collisions and increased reaction rate.
What graph shows the pathway of a reaction that absorbs energy?
A reaction that absorbs energy is endothermic and typically represented on a graph with a reactant energy level below the product energy level. This results in an increase in energy during the course of the reaction, with the energy barrier (activation energy) higher than that of an exothermic reaction.
