How would you know if a reaction was endothermic or exothermic?
An endothermic reaction is one in which thermal energy, or heat, is absorbed. If heat is absorbed in the reaction process, it is endothermic. By monitoring the temperature of the reactants in a reaction, an observer could identify an endothermic reaction through observation of a decrease in the temperature.
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.
Is Reactants are substances that exist after the reaction has taken place?
see i dont know
How do you know that the decomposition of limestone is an endothermic reaction?
Endothermic means that a reaction needs heat to occur. Limestone needs to be heated to decompose into calcium oxide and carbon dioxide
Is ammonium endo or exothermic?
endothermic but don't know why? As AN crystals are formed the reaction is exothermic. Endothermic when it melts back with water. This is the reason AN is used in cold packs.
Is baking bread a endothermic and exothermic?
Sounds like a homework question. We know that in an exothermic reaction, heat is taken out of the system and given to the surroundings. Whereas in an endothermic reaction, heat is pulled from the surroundings into the system. I am assuming you are thinking of the cookies as the system. So in this case, energy--in the form of heat--is being taken out of the oven and being put into the cookies. The cookies, using the energy increase in temperature, which bakes the cookies, creating the tasty little morsels of joy that cookies are.
When ammonium nitrate is mixed with water how would you know that the reaction is endothermic?
The temperature will decrease.
If the reaction gets hot is it an endothermic or an exothermic reaction?
The reverse reaction is not always endothermic or exothermic, the reverse reaction is the opposite of whatever the initial reaction is, so if the reaction is endothermic, the reverse reaction is exothermic and vise versa.
Is the reaction between copper sulphate and hydrochloric acid endothermic?
No, the reaction between copper sulfate and hydrochloric acid is exothermic, meaning it releases heat. This is because energy is released when the products are formed, making the overall reaction exothermic.
The production of a certain chemical is an endothermic reaction How is equilibrium affected by doubling the pressure in the system?
It is impossible to know without more information.
Endothermic means that heat has evaporated?
in an endothermic reaction the reacting substances are releasing energy, making them feel cold. i don't know what you mean by evaporating heat, but you cannot create or destroy energy if that helps.
What three ways would let you know that a reaction had taken place?
Changes in color: If the color of the reactants or products changes during the reaction, it is a sign that a chemical reaction has occurred. Formation of a gas: Production of gas bubbles or fizzing indicates a chemical reaction, such as in the reaction between an acid and a carbonate. Changes in temperature: If the reaction absorbs or releases heat, causing a change in temperature in the surroundings, it signals a chemical reaction has taken place.
