The reaction between Mentos and soda is primarily a physical reaction rather than a chemical one, resulting in an exothermic process. When Mentos are added to soda, the rapid release of carbon dioxide gas creates a vigorous eruption, releasing energy in the form of heat. This is due to the nucleation sites on the surface of the Mentos facilitating the rapid escape of dissolved gas from the liquid.
What else can I help you with?
Does phenol red mixed with calcium chloride and baking soda turn out to be a exothermic or endothermic?
The reaction between phenol red, calcium chloride, and baking soda is endothermic. The mixture will absorb heat from its surroundings as it undergoes the reaction, causing the temperature of the mixture to decrease.
Is drain cleaner endothermic or exothermic?
Drain cleaner is typically exothermic. When it is mixed with water, it produces heat as a result of an exothermic chemical reaction. This heat helps to dissolve and remove the clogs in the drain.
Is a test tube that feels cold to touch after two substances have been mixed is exothermic?
NO. If the test tube becomes hot, then the reaction taking place in the test tube is EXOTHERMIC. The reaction is releasing heat to the surroundings, and the test tube is part of the surroundings.
Is acid rain an exothermic or endothermic reaction?
The formation of acid rain involves an exothermic reaction. This occurs when pollutants like sulfur dioxide and nitrogen oxides combine with water vapor in the atmosphere to form sulfuric acid and nitric acid, releasing heat in the process.
Take about 2 g barium hydroxide in a test tube. Add 1 g of ammonium chloride and mix with the help of a glass rod. Is this an exothermic or an endothermic reaction?
This is an endothermic reaction. When barium hydroxide and ammonium chloride are mixed, they react to form barium chloride, ammonia, and water. This reaction absorbs heat from the surroundings, causing a decrease in temperature.
Why are you instructed to feel the outside of the test tube after two chemicals are mixed in steps 4 and 5?
Because some chemical reactions result in an exothermic or endothermic reaction in the products.
What mixed with pop gives off a big reaction?
Mentos
What is the difference between Endothermic and Exothermic in five to ten points?
Endothermic and exothermic are both terms used for the transfer of heat through a chemical reaction. When the mixed chemicals give off more heat than before (Become hotter), than an exothermic reaction has occurred. This is where energy is given off to the surroundings, causing the temperature to rise. Exothermic reactions are the opposite to this, where the container holding the chemicals becomes colder. This is because energy was required and heat was taken from the surroundings for the reaction to occur. Hope this helps.
How will you control the temperature of an endothermic reaction in a mixed reactor?
Studies indicate the best way to control the temperature of the endothermic reaction in a mixed reactor is through making adjustments to the coolant temperature. There processes are highly complex.
How heating and mixing increase the solubility?
An endothermic reaction is what increases solubility. When something is heated, and then continues moving (being mixed) it creates a better environment for an endothermic reaction.
Why is it important to observe temperature change when two chemical are mixed?
Observing temperature change when two chemicals are mixed can provide insight into whether a chemical reaction has occurred. An increase or decrease in temperature may indicate that the reaction is exothermic or endothermic, respectively. Monitoring temperature change can also help determine the reaction rate and the efficiency of the reaction.
When ammonium nitrate is mixed with water how would you know that the reaction is endothermic?
The temperature will decrease.
