What else can I help you with?
Is a cold pack an endothermic reazction?
The reaction is endothermic.
Is cold pack exothermic or endothermic?
Endothermic- a change in which energy is taken in. The melting of ice is an endothermic change. Ice absorbs thermal energy from its surroundings when it melts. That's why you pack drinks and food in an ice-filled picnic cooler to keep them cold. So yes an ice cube is endothermic.
Which type of reaction requires more activation energy?
Endothermic reactions typically require more activation energy compared to exothermic reactions. This is because in an endothermic reaction, energy is absorbed from the surroundings to break bonds and form new ones, which requires more energy input to overcome the activation barrier.
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.
Do exothermic reactions require any activation energy?
No activation energy can also be needed by endothermic reactions.
Is a cold pack an endothermic reazction?
The reaction is endothermic.
Explain which type of reaction exothermic or endothermic would be required to make a cold and a cold pack or hot pack?
You would have to have an Eacthomatdid reaction of chemcal chance to change a cold pack to a hot pack.

What type of reaction is occurring when you activate an instant cold pack?
endothermic because the energy is absorbed
When you activate an instant cold pack water mixes with a chemical and the pack gets very cold This is an example of?
an endothermic reaction where the chemical reaction absorbs heat from its surroundings, causing the pack to cool down.
Why does a cold pack get cold when the chemical reacts?
A cold pack creates a endothermic reaction when the chemical reacts, which means that energy is taken from the surrounding, which makes the packaging cold. it is the opposite with a heat pack, an exothermic reaction is created which releases the energy into the surrounding creating the heat. Hope this helped.
When you activate an instant cold pack and water mixes with a chemical and the pack gets very cold what example is this?
This is an example of an endothermic chemical reaction, where energy is absorbed from the surroundings in the form of heat, causing the pack to become cold. The reaction between the chemicals in the instant cold pack and water absorbs heat from the environment, resulting in the cooling effect.
Does endothermic have high or low activation energy?
An endothermic reaction would not necessarily have either a high or low activation energy; it could be either and would depend on the reactants. Also, the activation energy alone does not determine if a reaction is endothermic or exothermic; a low or high activation energy could be part of an endothermic or exothermic reaction, again depending on the reactants.

Which of the following is endothermic a dry ice evaporating b a sparkler burning c the reaction that occurs in a chemical cold pack often used to ice athletic injuries?
Dry ice evaporating is endothermic-->+DeltaH A sparkler burning is exothermic--->-DeltaH The reaction that occurs in a chemical cold pack often used to ice athletic injuries is endothermic--->+DeltaH
