What is the name given to a reaction the gives off energy?
A reaction that gives off energy is an exothermic reaction. The reaction will give off energy in the form of either heat or light An example of an exothermic reaction would be the curing of concrete. One chemical reaction that will give off heat is the mixture of Caustic Soda and water. The water dissolves the Caustic Soda which in turn generates heat. There are two types of reactions. Exothermic reactions give off heat, and endothermic reactions require that heat be added to make them work. Be careful with exothermic reactions. A rapid, energetic exothermic reaction is called an "explosion".
What is the scientific name for reactions that give out energy?
The scientific name for the reaction that gives out energy is exothermic
What is the reactions and the products of the reactions?
Question is to be edited. What isreactions.......Not reactions it has to be reactants.Reactants are those which come into reaction and products are those the outcome of such reaction.CH4 + 2 O2 gives CO2 + H2O CH4 , O2 are reactants. CO2 , H2O are products.
What is atom economy reaction?
The question itself makes no real sense. The Atom economy of a chemical reaction is calculated using the formula Atom economy = mass of useful product / mass of products x 100 This effectively gives the percentage of the mass of reactants turned into useful products thus allowing a calculation of waste from a given process.
What is the name of the type of reaction that produces heat?
exothermic reactions1) Combustion: A combustion reaction is when oxygen combines with another compound to form water and carbon dioxide. These reactions are exothermic, meaning they produce heat. An example of this kind of reaction is the burning of napthalene:C10H8 + 12 O2---> 10 CO2 + 4 H2O
What r products of chlorine and humic acid reaction?
Chlorinated products of humic acid (or polyphenols) are formed (by substitution and or addition reactions) which gives them an awefull odor.
What reaction gives out energy?
If by energy you mean heat energy exothermic reactions.
What is a reaction called that gives off heat?
exothermic reactions-gives off heat
What is a chemical reaction gives off heat called?
exothermic reactions-gives off heat

The scientific name for the reaction that gives out energy is exothermic
What are differences between endothermic and exothermic reactions examples?
The main differences between exothermic reactions and endothermic reactions are: Exothermic reactions are reactions that give off energy (light, electrical or mainly heat), causing the surroundings to warm up. Endothermic reactions are reactions that absorb energy, causing the surroundings to cool down. The products of an exothermic reaction have less energy, or less total enthalpy, than of it's reactants. This is due to the reactants containing more stored energy because energy from external sources is not required. This also gives the products more stability because in order to achieve a reversible reaction and break the chemical bonds of the products, you will need to apply more energy to it. The opposite is for endothermic reactions. The products of the reaction have a greater total enthalpy of the reactants, causing the reactants stored energy to decrease. This produces less stable products that need less energy to break their bonds in a reversible reaction. Finally most exothermic reactions are spontaneous, where as most endothermic reactions are not spontaneous as they generally need energy applied to them before they start.
How is energy involved in a chemical reaction?
Activation energy is needed to start a chemical reaction. This energy is used to join the reactants together or break them apart. If a reaction is exothermic then it gives energy out. If it is endo thermic then the reaction takes energy in.
Why amount of reactant and product do not change in reversible reaction?
The amount of reactants and products do not change in reversible reactions because, in a chemical reaction, matter is neither created nor destroyed -- it is only rearranged. This is the law of conservation of matter.
What shows the relationship between the reactants and products in a chemical reaction?
the coefficients of a balanced reaction
What type of reaction gives off heat Does it feel hot or cold?
Endothermic reactions increase their enthalpy by absorbing heat
