What is the heat balance equation for a exothermic reaction?
For an exothermic reaction, heat should appear as a product since heat is given off. Thus, it would be A + B ==> C + D + heat
What equation indicates an endothermic equation?
An endothermic reaction occur with heat absorption.
What equation show exothermic reaction?
An exothermic reaction is represented by an equation in which the products have lower energy than the reactants. This is typically indicated by the release of heat as a product in the reaction. For example: A + B → C + heat.
How is an exothermic reaction in an equation?
If the reaction is exothermic, this means heat is released and would thus appear as a PRODUCT, i.e. it would appear on the right side of the equation. This would be written as A + B ==> C + D + heat
What are the general formulas for the five main types of reactions?
Synthesis - A + B = AB Decomposition - AB = A + B Single Replacement - A + BC = B + AC Double Replacement - AB + CD = AD + CB Combustion - either a synthesis, decomposition, or single replacement reaction. It combines with oxygen.
Ask us anythingWhich of the following indicates an endothermic reaction?
A + B + heat —> C + D

Which indicates an exothermic reaction?
A+B —> C+D+ HEAT (Apex)
What is the word used to describe a chemical reaction in which energy is released?
Any chemical reaction that releases energy is called an exothermic action. The equations for an exothermic reaction between substance A and substance B would be: A + B --> AB + Heat The heat represents the energy and we can tell it is being released because it is on the product side of the equation. The reverse reaction would be endothermic, meaning it requires energy, heat would be on the reactant side and the equation would be: AB + Heat --> A + B To sum things up, an exothermic reaction releases energy and heat will be on the product side of the equation. An endothermic reaction requires energy and heat will be on the reactant side of the equation.
How is heat included in the equation of an exothermic reaction?
Heat is written as a product of the reaction (apecs answer)
Is oxidation a exothermic or endothermic reaction?
it is exothermic b/c it gives off heat
What equation indicates an endothermic equation?
An endothermic reaction occur with heat absorption.
What type of reaction is shown in this thermochemical equation A plus B plus Heat -- C plus D?
The reaction shown in the thermochemical equation is an exothermic reaction. This is because heat is a reactant (on the left side of the equation) and is released during the reaction.
What does a enzyme do A Adds heat to a reaction speeding it up B Lowers the activation energy of a reaction C Cools a reaction slowing it down D Raises the activation energy of reaction?
B. Lowers the activation energy of a reaction. Enzymes facilitate chemical reactions by decreasing the energy needed to start the reaction, thus speeding up the overall process.
What equation show exothermic reaction?
An exothermic reaction is represented by an equation in which the products have lower energy than the reactants. This is typically indicated by the release of heat as a product in the reaction. For example: A + B → C + heat.
What is the difference between heat of reaction and molar heat of reaction?
Heat of a reacion is the totall amount of heat a reaction produces. Molar heat of a reaction is the heat produced/mol if you have the molar hear of the reaction you can calculate the heat of the reaction based on the moles of reactants you have
Which of the following describes an exothermic reaction A. ht reactants equals 0 B. ht reactants ht products C. ht equals ht D. ht ht?
Hf, reactants > Hf, products apex
