What are reactions that take in heat energy?
Endothermic reactions absorb heat energy from their surroundings in order to proceed. This results in a decrease in temperature of the surroundings as the reaction absorbs the energy to break bonds and form new ones.
Is sparkler burning endothermic or exothermic?
Endothermic reactions take in heat from the surroundings (and make it cooler), exothermic reactions give out heat to the surroundings making it hotter. Get too close to a sparkler and you'll find it is very hot! This is because it is an exothermic reaction.
Which reaction represents chemical bonds being made?
I would guess that the answer here is endothermic or unfavourable. Endothermic reactions take in energy from the surroundings (in the form of heat). Formation of additional bonds between carbons anyway is generally unfavourable, therefore it needs to take in energy from its surroundings (thus the reaction vessel becomes cold)
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is a Exothermic b Reactant c Balanced d Endothermic?
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is endothermic.
Is it true that evaporation and condensation take place when water gains heat energy?
Evaporation is an endothermic process.Condensation is an exothermic process.
What is the name given to reactions which take in heat?
An endothermal (or endothermic) process is the name of the process in which heat is taken in. In an exothermal (or exothermic) process, heat is released.
How does an exothermic reaction differ from n endothermic reaction?
An exothermic reaction releases heat to its surroundings, resulting in a temperature increase. In contrast, an endothermic reaction absorbs heat from its surroundings, causing a decrease in temperature.
How does an endothermic reaction change the entropy of the surroundings?
An endothermic reaction which absorbs heat from the surroundings decreases the entropy of the surroundings. This is because the surroundings lose thermal energy during the reaction, leading to a decrease in the disorder or randomness of the surroundings.
What are reactions that take in heat energy?
Endothermic reactions absorb heat energy from their surroundings in order to proceed. This results in a decrease in temperature of the surroundings as the reaction absorbs the energy to break bonds and form new ones.
Define endothermic and exothermic reaction in terms of sign of?
Endothermic are those which take heat so the sign of energy released will be negative and of change in heat is whcih is equal to heat of product - heat of reactant so in this case Hp - hR = -ve
A reaction that absorbs energy is called?
Endothermic-take in Heat, as opposed to exothermic which gives off heat-like a fire or explosion.
If heat must be added to a chemical reaction for the reaction to take place the reaction is?
Endothermic reactions need heat. Exothermic reactions give off heat.
Is sparkler burning endothermic or exothermic?
Endothermic reactions take in heat from the surroundings (and make it cooler), exothermic reactions give out heat to the surroundings making it hotter. Get too close to a sparkler and you'll find it is very hot! This is because it is an exothermic reaction.
Is a test tube that feels cold to touch after two substances have been mixed is exothermic?
NO. If the test tube becomes hot, then the reaction taking place in the test tube is EXOTHERMIC. The reaction is releasing heat to the surroundings, and the test tube is part of the surroundings.
Endothermic and exothermic reaction?
An exothermic reaction releases energy, usually to the surroundings. There is a net loss of energy from the reactants. However, exothermic reactions also need a little energy to get started, but this is less than the eventual amount given out. An endothermic reaction takes in energy, also usually from the surroundings. There is a net gain of energy into the reactions. Again, a little energy is lost, but this is hardly anything compared to the amount taken in.
Which reaction represents chemical bonds being made?

Formation of additional bonds between carbons anyway is generally unfavourable, therefore it needs to take in energy from its surroundings (thus the reaction vessel becomes cold)
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is a Exothermic b Reactant c Balanced d Endothermic?
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is endothermic.
