Which is always true of an endothermic reaction?
An endothermic reaction consumes energy, and the reduction of energy does lower temperature. Of course, the actual temperature of the chemicals in question may be subject to other simultaneous influences. If you have a solution in which there is an endothermic reaction taking place, but you are also heating the solution to help drive the reaction, you will not observe a lower temperature.
Does endothermic or exothermic get colder?
Yeah, endothermic means that the heat is basically sucked out of it... or released while in an exothermic reaction, the heat is gathered or taken in. Take for example hot gas in a glass container: if it is cooled down of placed into a tub of ice, the gas will condense and the gas forms into droplets of liquid on the sides of the container and then drops to the bottom once there's enough of it.
Is dissolving glucose in water endothermic reaction?
No, because it's not a reaction. Dissolving is a physical, not a chemical, process. Some things dissociate as a result of being dissolved, and this dissociation can be treated as a chemical reaction, but glucose is not one of them. It is slightly endothermic, though, if that's the part you were really interested in.
Why ammonium chloride in water becomes cold?
When ammonium chloride dissolves in water, it undergoes an endothermic reaction, meaning it absorbs heat from the surroundings. This absorption of heat causes the temperature of the solution to decrease, and as a result, the solution feels cold to the touch.
What is a good hypothesis for endothermic reactions?
A good hypothesis for endothermic reactions could be: "Increasing the temperature will result in a higher rate of the endothermic reaction, as more energy is needed to break the bonds of the reactants."

During an endothermic chemical reaction what is the source of energy that causes the reaction to continue?
In an endothermic chemical reaction, the source of energy that drives the reaction is typically heat absorbed from the surroundings. This energy input is necessary for breaking bonds in the reactants and forming new bonds in the products. As a result, the reaction absorbs heat, leading to a decrease in the temperature of the surroundings.
How can an endothermic reaction be spontaneous at room temperature?
An endothermic reaction can be spontaneous at room temperature if the increase in entropy of the system is large enough to overcome the energy input required for the reaction. This can happen if the products of the reaction have higher entropy than the reactants. As a result, the overall change in free energy can be negative even though the reaction is endothermic.
Which salt will result in a temperature decrease when added to water?
Ammonium nitrate (NH4NO3) is a salt that will result in a temperature decrease when added to water due to its endothermic dissolution process. This means that as the salt dissolves in water, it absorbs heat from the surroundings, causing a decrease in temperature.

What effect does the removal of heat have on the equilibrium position?
The temperature of a reaction will entirely change th equilibrium position for any given reaction. If I'm right, as you increase the temperature, the equilibrium shifts closer to the endothermic reaction as there is more heat to consume. It may also, of course, change other properties of the substances involved in the reaction, but that depends on the chemicals.
What happens to the energy absorbed during and endothermic reaction?
During an endothermic reaction, energy is absorbed from the surroundings, typically in the form of heat. This energy is used to break chemical bonds in the reactants, allowing the reaction to proceed. As a result, the temperature of the surrounding environment may decrease, and the products of the reaction have higher energy than the reactants. Overall, the absorbed energy is stored within the chemical bonds of the products.
What is known about a reaction with the positive enthalpy?
A reaction with a positive enthalpy change, often referred to as an endothermic reaction, absorbs heat from its surroundings. This means that the products of the reaction have a higher energy content than the reactants. As a result, the temperature of the surroundings may decrease during the reaction. Examples include photosynthesis and the dissolution of certain salts in water.
Is dissolving glucose in water endothermic reaction?

How does increasing temperature effect endothermic reaction?
You can use LeChatelier's Principle to solve this problem. For an endothermic reaction A+heat<-->B Thus, by increasing the heat, you are shifting the equilibrium towards the reactants. The reaction will adjust itself by shifting the equilibrium to the right (producing more of the product).
What is a good hypothesis for endothermic reactions?
