Not always. In a chemical reaction, the process can be either endothermic or exothermic. Endothermic reactions absorb heat from the surroundings, while exothermic reactions release heat into the surroundings. The specific reaction will determine whether it is endothermic or exothermic.

An endothermic reaction is one in which heat is transferred from the surroundings to the reactants.?
Yes, this affirmation is true.
Does anybody know the formula for endothermic reaction and exothermic reaction?
An endothermic reaction absorbs heat from its surroundings, while an exothermic reaction releases heat to its surroundings. The general formula for an endothermic reaction is: reactants + heat → products, and for an exothermic reaction: reactants → products + heat.
How do you predict if a reaction will be exothermic or endothermic?
You can predict if a reaction will be exothermic or endothermic by comparing the energy of the products and reactants. If the products have lower energy than the reactants, the reaction will be exothermic (energy released). Conversely, if the products have higher energy than the reactants, the reaction will be endothermic (energy absorbed).
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.
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?
Yes, endothermic reactions absorb heat from their surroundings, causing the products to have higher energy than the reactants. This results in an overall increase in the energy of the system.
In an endothermic reaction which has the lower energy?
In an endothermic reaction, the products have higher energy than the reactants. This means the reactants have lower energy compared to the products.
which of the following describes an endothermic reaction?
Hf, products > hf, reactants
Are the products favored over the reactants or the reactants favored over the products?
The products are favored over the reactants if the reaction is exothermic, releasing energy. Conversely, the reactants are favored over the products if the reaction is endothermic, requiring energy input.
An endothermic reaction is one in which heat is transferred from the surroundings to the reactants.?
Yes, this affirmation is true.
In an endothermic reaction are the products more or less stable than the reactants and explain your answer?
In an endothermic reaction, the products are generally less stable than the reactants. This is because the reaction absorbs heat from the surroundings to proceed, indicating that the products have higher potential energy than the reactants.
Does anybody know the formula for endothermic reaction and exothermic reaction?
An endothermic reaction absorbs heat from its surroundings, while an exothermic reaction releases heat to its surroundings. The general formula for an endothermic reaction is: reactants + heat → products, and for an exothermic reaction: reactants → products + heat.
How do you predict if a reaction will be exothermic or endothermic?
You can predict if a reaction will be exothermic or endothermic by comparing the energy of the products and reactants. If the products have lower energy than the reactants, the reaction will be exothermic (energy released). Conversely, if the products have higher energy than the reactants, the reaction will be endothermic (energy absorbed).
What is the difference of endothermic reaction from exothermic reaction?
Endothermic reactions absorb heat from their surroundings, resulting in a decrease in temperature, while exothermic reactions release heat to their surroundings, causing an increase in temperature. In endothermic reactions, the products have more energy than the reactants, whereas in exothermic reactions, the products 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 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.
