An ice cube melts after being left on the table over an extended period of time Exothermic or 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.

Is wood being chopped an exothermic or endothermic reaction?
No it is not
Contrast endothermic and exothermic reactions?
Endothermic reactions are chemical reactions that use heat as part of the reactant. Heat is absorbed into the reaction in order for it to continue. Exothermic reactions are chemical reactions that release heat as a product of the reaction.
Is a plastics becoming brittle after being left in the sun a exothermic or endothermic?
Endothermic reactions are characterized by positive heat flow, therefore the plastic left in the sun is endothermic
When iron rusts is it an endothermic or exothermic reaction?
It is an endothermic reaction because in endothermic reaction energy is added .In that reaction nitrogen does not react with oxygen without energy added in the shape current . In that reaction 3000`current is applieded to take reaction b/w nitrogen and oxygen
What are the advantages and disadvantages of exothermic and endothermic reactions?
The big advantage to being exothermic is that the animals save a huge amount of energy. In contrast, endothermal or warm blooded animals use roughly one third of the energy they ingest for heating. The big disadvantage in being exothermic is that moving, digesting and reproducing generaly use more energy and take longer to start up.

No it is not
When a plastic bottle turns brittle when being left out in the sun is this reaction endothermic or exothermic?
endothermic
Is burning a match an endothermic or exothermic change?
Burning a match is an exothermic change because energy is being released.
Contrast endothermic and exothermic reactions?
Endothermic reactions are chemical reactions that use heat as part of the reactant. Heat is absorbed into the reaction in order for it to continue. Exothermic reactions are chemical reactions that release heat as a product of the reaction.
Would you describe the reaction of calcium in water as being exothermic or endothermic?
The reaction between calcium and water is very exothermic.
Is plastics becoming brittle after being left in the sun endothermic or exothermic?
endothermic glad to see you're doing your homework (:

Are exothermic reactions decomposition reactions or are they synthesis reactions?
Synthesis reactions are generally characterized by being exothermic. Decomposition reactions are usually endothermic.
Is a firecracker exploding an example of an endothermic reaction or an exothermic reaction?
Exothermic Reaction because the fizzing is CO2 being released as heat (energy).
Is magnesium ribbon burns an endothermic reaction or an exothermic reaction?
The reaction is highly exothermic as heat energy is released from the system to the surroundings whereas in endothermic the heat is absorbed from the surroundings into the system and you can also observe or see the smoke coming out of the apparatus in which the reaction is occurring or taking place.Heat energy is being released in the form of smoke.Therefore the reaction is exothermic.

How exothermic and endothermic relate to responding to external changes?
Exothermic and endothermic both have to adapt to the climate changes. For example exothermic need to move in the sun or light source when they are cold and move to a cool place when they are hot. Endothermic have to let their body temperature warm up by being in the warmest place possible, when they are cold they instantly start trying to warm up automatically.
