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.
What else can I help you with?
What equation indicates an endothermic equation?
An endothermic reaction occur with heat absorption.
How is an endothermic reaction identifed in an equation?
An endothermic reaction can be identified in a chemical equation by the presence of heat or energy being absorbed, which is often indicated by a positive value for the enthalpy change (ΔH). In the equation, this may be shown by including heat as a reactant, such as in the equation: A + B + heat → C. Additionally, if the reaction results in a temperature decrease in the surroundings, it further confirms the reaction is endothermic.
How is heat included in an equation of an exothermic reaction?
Heat is written as a product of the reaction (apecs answer)
What is a general chemical equation for an endothermic double-replacement reaction?
A general chemical equation for an endothermic double-replacement reaction can be represented as: [ AB + CD \rightarrow AD + CB + \text{heat absorbed} ] In this equation, (AB) and (CD) are two ionic compounds that exchange partners to form new compounds (AD) and (CB), while absorbing heat from the surroundings, indicating that the reaction is endothermic.
If heat is required for a reaction to occur what type of reaction is it?
If heat is required for a reaction to occur, it is an endothermic reaction. Endothermic reactions absorb heat from their surroundings in order to proceed.
What is heat included in equation of an endothermic reaction?
The heat in an endothermic reaction is included as a reactant on the left side of the equation, and has a positive value.
Is an endothermic reaction identified in an equation?
Heat is included as a reactant in the reaction.
What is heat included in the equation of an endothermic reaction?
In an endothermic reaction, heat is included as a reactant in the chemical equation to show that the reaction absorbs energy from the surroundings in the form of heat to proceed. The reaction is usually represented as products being greater in energy content than the reactants due to the input of heat.
How is heat included in the equation of the endothermic reaction?
In an endothermic reaction, heat is included as a reactant in the chemical equation. This indicates that the reaction requires heat to proceed, and it is absorbed from the surroundings during the process. The heat is typically written as a reactant on the left side of the equation.
How is an endothermic reaction indicated in an equation apex?
An endothermic reaction in an equation is typically indicated by the presence of heat as a reactant. For example, in a chemical equation, if heat is shown as a reactant (usually on the left side of the arrow), it suggests that the reaction requires energy input to proceed, making it an endothermic reaction.
How is an endothermic reaction indicated in an equation?
An endothermic reaction is indicated in an equation by a positive heat term on the product side, showing that the reaction absorbs heat from the surroundings. This is typically represented by the ΔH value being positive in the reaction equation.
How is endothermic reaction identified in an equation?
heat is included as a reactant in the reaction - apex
What equation indicates an endothermic equation?
An endothermic reaction occur with heat absorption.
How is an endothermic reaction identifed in an equation?
An endothermic reaction can be identified in a chemical equation by the presence of heat or energy being absorbed, which is often indicated by a positive value for the enthalpy change (ΔH).

Additionally, if the reaction results in a temperature decrease in the surroundings, it further confirms the reaction is endothermic.
A reaction that absorbs energy is called?
Endothermic-take in Heat, as opposed to exothermic which gives off heat-like a fire or explosion.
How can you tell if a chemical equation is endothermic?
An endothermic reaction absorbs heat from its surroundings, causing a decrease in temperature. In a chemical equation, if the products have a higher energy content than the reactants, it indicates that the reaction is endothermic. This can be determined by examining the enthalpy change (∆H) of the reaction.
What happens in an endothermic reaction?
An endothermic reaction need heat to occur.
