When you activate an instant cold pack water mixes with a chemical and the pack gets very cold This is an example of?
its an endothermic reaction
When you activate an instant cold pack and water mixes with a chemical and the pack gets very cold what example is this?
It is an example of an endothermic reaction. It is absorbing heat.
What happens to the reaction during endothermic and exothermic reaction?
During an endothermic reaction, heat is absorbed from the surroundings, causing the reaction to feel cold. The reactants have less energy than the products, so energy is absorbed to form the products. In an exothermic reaction, heat is released into the surroundings, making the reaction feel hot. The reactants have more energy than the products, so energy is released during the reaction.
When cold temperatures are produced in a chemical reaction the reaction is known as?
Endothermic reaction
What can be mixed to produce a very cold effect that doesn't give off an unsafe gas?
Instant cold packs use water and ammonium nitrate. The ammonium nitrate is a powder found inside the cold pack, and the water is inside a plastic container inside the cold pack. When the plastic container containing the water is broken and mixed with the ammonium nitrate, the water dissolves the ammonium nitrate, which is overall an endothermic reaction, causing the cold pack to get cold.

Is nuclear chain reaction is called fusion?
The idea of nuclear fusion occurring at room temperature is called cold fusion.
What happens to the reaction during endothermic and exothermic reaction?
During an endothermic reaction, heat is absorbed from the surroundings, causing the reaction to feel cold. The reactants have less energy than the products, so energy is absorbed to form the products. In an exothermic reaction, heat is released into the surroundings, making the reaction feel hot. The reactants have more energy than the products, so energy is released during the reaction.
Is ice hot?
Ice is cold, in the form of water put in a freezer. But some special reactions, such as Instant Ice, emit heat as the supercooling reaction releases energy.
What if yeast does not activate?
Might be old or the water is too cold to activate it or too hot and killed it.
Can you make a rocket with a instant cold pack?
no
When a chemical cold pack is activated it becomes cool to the touch what is happening terms of energy?
C An endothermic reaction is occurring, transforming chemical potential energy into thermal kinetic energy.
Instant cold packs can be reused?
Instant cold packs cannot be reused once they are activated. The chemical makeup inside the package was created for one time use.
Is does not react with cold water is a physical property?
A reaction with water (hot or cold) is a chemical reaction.
What is the chemical equation for ammonium nitrate decomposes into nitrogen and water?
When ammonium nitrate (NH4NO3) is mixed with water, the dissolution of ammonium nitrate occurs - that is, it is broken up into its ions. This is endothermic, and is the driving reaction behind instant cold packs.
What is the cold can a flame be?
A flame cannot be any cold but always hot even at the first instant it is lit.
