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.
How can an endothermic reaction be spontaneous at room temperature?
Exothermic, as endothermic reactions require activation energy.
Which type of reaction requires more activation energy?
endothermic reaction
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.

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
What type of reaction is occurring when you activate an instant cold pack?
endothermic because the energy is absorbed
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.

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.
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.
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
