When melt ice it gets warmer so it is endothermic and when mix vinegar and baking soda it gets colder then would it be exothermic?

Um. Yes, no, maybe. Your grammar skills could use some work, and the result is that I'm not sure if you've actually grasped the basic concept of endo- vs. exothermic. There's also some substantial basic science errors contained in there. Let's break it down point by point to show you why I'm really reluctant just to say "yes" or "no."
Ice melting does not actually get warmer: the energy added to the system goes into what's called the heat (or enthalpy) of fusion, or converting the solid form into the liquid form. After it's liquid, then it can begin getting warmer, but just-melted water and just-about-to-melt ice are the same temperature. The process of melting ice is indeed endothermic, but you've got the reason why wrong.
"Mixing" things tends to be very slightly endothermic, though not always. I assume, though, that when you say "mixing" baking soda and vinegar you're talking about the reaction between sodium hydrogen carbonate and ethanoic acid, which is endothermic. It does, however, get cooler, as you state.
answ2. In agreeing with the above, simply put, exothermic means "giving off heat", such as a fire - it gets warmer.
And an endothermic reaction would absorb heat - it would get colder. Keep up the work.

When solid kbr is dissolved in water the solution gets colder is this endothermic or exothermic?
endothermic.
What reaction will cause the contain to feel colder?
Endothermic reactions can cause the container to feel colder. A simple example would be just mixing baking soda and vinegar.
Is ice endothermic or exothermic?
Definitions Exothermic - accompanied by, or requiring, the release of heat. Endothermic - accompanied by, or requiring, the absorption of heat. Now, does the melting ice get warmer or colder? If it gets colder, then it is exothermic. If it gets warmer, then it is endothermic. Consider how we make ice - we put water into a cold place so that it gets colder with time.
When you mix vinegar and baking soda together why is it cold?
Baking soda and vinegar gets cold in a reaction called an endothermic reaction. Ectothermic reactions get warm, endo cold. All the heat is taken in by the baking soda and used as energy. If you add more baking soda, more baking soda will take in energy and make it colder. Source(s): Fith Grade science project done in Los Gatos, CA
An endothermic reaction causes the surroundings to?
An endothermic reaction is one that absorbs heat energy from the surrounding environment. Therefore, an ongoing endothermic reaction will cause its surroundings to become colder. In contrast, an exothermic reaction radiates heat energy into its surroundings, which will cause the ambient environment to get warmer.
What is one similarity between exothermic reaction and an endothermic reaction?
Endothermic reactions and exothermic reactions all involve something called an enthalpy change: a change in the amount of energy a chemical contains. The difference here is that exothermic reactions release heat energy to their surroundings, whereas endothermic reactions absorb heat from their surroundings (in effect, getting colder).
When oil is burned is it endothermic?
Fire creates an exothermic reaction, not endothermic. To be endothermic, the reaction must draw in heat from its surroundings, thereby making things colder.
Is the reaction between copper sulphate and hydrochloric acid endothermic?
If the test tube containing the reactants mixture became hotter then it is exothermic, and if it became colder then it is endothermic. You must do the reaction to know which is which!
Is endothermic energy occurring when crystals dissolve in water and the container gets hot?
No.I know that in endothermic reactions things absorb heat or get colder. In exothermic reactions they release heat or get warmer. So, since the container gets hot I guess the energy is exothermic.
What is given off in all energy changes?
energy is released which makes it hotter because it is an exothermic reaction, or energy is absorbed which makes it colder and an endothermic reaction =]
Is ice cream a exothermic or endothermic reaction?
endothermic reaction. ice - cream melts because it absorbs heat from the surrounding thus increasing its temperature. exothermic reaction is when a substance reacts with something, thus releasing heat.
How melting is endothermic?
The process of melting is endothermic because you are adding heat (or energy) to the object. When you add heat or energy to an object it begins to melt , Which tells you the object has reached its melting point or the temperature that the object melts at.endothermic is adding heat or energy (ENdothermic means ENtering)exothermic is removing heat or energy (EXothermic means EXiting).Conversely, the process of freezing is exothermic.And easy way to remember this is that when ice melts it makes things cold. This is because it is sucking in the heat.
