An endothermic reaction is one in which heat is transferred from the surroundings to the reactants.?
Yes, this affirmation is true.
What is the sign for Energy change of an endothermic reaction?
The products of the reaction will have less energy than the reactants
Will there be a reaction if all reactants and possible products are aqueous?
Yes, between reactive chemicals there is likely to be a reaction which will lead to precipitation if all the reactants and possible products are aqueous. The reactants, although aqueous, could fail to react if they are endothermic.
What is a type of chemical reaction where the energy of the products is less than the energy of the reactants?
When a reaction has products that have a lower temperature than the reactants did, the reaction is endothermic.
How us heat included in the equation of an endothermic reaction?
This question is oddly worded, but I am assuming that the author means to ask "in chemical equations for endothermic reactions, is the change in energy (delta H) positive or negative?". For endothermic reactions, heat is absorbed during the reaction, so the energy of the products is higher than the energy of the reactants. Since dH = H(products) - H(reactants). Therefore, dH is positive.
Do endothermic reaction have reactants with more energy than its products?
Kinetic energy has more energy than products.
which of the following describes an endothermic reaction?
Hf, products > hf, reactants
An endothermic reaction is one in which heat is transferred from the surroundings to the reactants.?
Yes, this affirmation is true.
What is the sign for Energy change of an endothermic reaction?
The products of the reaction will have less energy than the reactants
The elements or compounds produced by a chemical reaction are known as what?
The substances produced by a chemical reaction are known as Products. The substances that are reacted are the Reactants.
Will there be a reaction if all reactants and possible products are aqueous?
Yes, between reactive chemicals there is likely to be a reaction which will lead to precipitation if all the reactants and possible products are aqueous. The reactants, although aqueous, could fail to react if they are endothermic.
What is the criteria in terms of temperature changes for exothermic and endothermic reactions?
Endothermic reactions draw heat from the reactants / products and the environment, so they tend to get cooler as the reaction proceeds. Exothermic reactions release heat to the reactants / products and the environment, so they tend to get hotter as the reaction proceeds.
Do reactants and products break during a chemical reaction?
In a reaction, the bonds in reactants are broken down (endothermic) and new bonds formed. The new bonds formed (exothermic) will result in the formation of the products.
What is a type of chemical reaction where the energy of the products is less than the energy of the reactants?
When a reaction has products that have a lower temperature than the reactants did, the reaction is endothermic.
Where does the energy come from that is needed for an endothermic reaction the products or the reactants?
-The Productt/reactant solution -The envoriment when no solution is involved
In an endothermic reaction are the products more or less stable than the reactants and explain your answer?
The products of an endothermic reaction are less chemically stable. They required an input of energy to create so naturally they are at a higher energy state.
What is the best term to describe a chemical reaction in which the reactants have less potential energy than the products?
A chemical reaction whose reactants have less potential energy than the products would be called an endothermic reaction.
