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.
What else can I help you with?
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
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.
Differentiate exothermic from endothermic reactions?
Exothermic reactions release heat energy to the surroundings, usually in the form of light or heat, resulting in a temperature increase. In contrast, endothermic reactions absorb heat energy from the surroundings, resulting in a decrease in temperature as the surroundings get colder.
What is the name of a reaction that occurs when products become colder?
This reaction is called an exothermic reaction. It releases heat to the surroundings as the products lose energy and become colder.
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 solid kbr is dissolved in water the solution gets colder is this endothermic or exothermic?
The process of dissolving solid KBr in water and the resulting decrease in temperature is an exothermic reaction. This means that heat is being released to the surroundings during the dissolution process.
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 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 the reaction between copper sulphate and hydrochloric acid endothermic?
No, the reaction between copper sulfate and hydrochloric acid is exothermic, meaning it releases heat. This is because energy is released when the products are formed, making the overall reaction exothermic.
Difference between endothermic and exothermic?
Endo draws heat from around it. Exo gives off heat. Example: Ice melting is a endothermic reaction. A match lighting is an exothermic reaction.An exothermic reaction releases heat to it's surroundings. The change in energy is negative. An example is combustion of natural gas.An endothermic reaction absorbs heat, so the temperature of the surroundings drops. The energy is positive. An example is melting ice cubes.
