Why burning a candle is an exothermic reaction not endothermic?
The reaction releases heat and light to its surroundings, so it is exothermic.
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.
When paint dries is it considered an exothermic reaction?
Yes, completely because there is no other chemical added to the paint to create a chemical reaction or to act as a internal catalyst.
Is baking bread a endothermic and exothermic?
Sounds like a homework question. We know that in an exothermic reaction, heat is taken out of the system and given to the surroundings. Whereas in an endothermic reaction, heat is pulled from the surroundings into the system. I am assuming you are thinking of the cookies as the system. So in this case, energy--in the form of heat--is being taken out of the oven and being put into the cookies. The cookies, using the energy increase in temperature, which bakes the cookies, creating the tasty little morsels of joy that cookies are.
Is sweating a chemical reaction?
Oddly enough, evaporation is endothermic. To tell the difference, simply ask yourself, must heat be added or taken away for a phase change to occur. If heat must be added it is endothermic, if heat must be taken away it is exothermic. In the case of evaporation in most cases you must raise the temperature for a substance to evaporate, thus it is endothermic.
If rubidium is added to water will it be endothermic or exothermic?
The reaction is very exothermic.
When sodium hydroxide is added to water the reaction is endothermic or exothermic?
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 happens when dilute sulphuric acid is added to zinc granules . Is it an exothermic or an endothermic reaction?
The reactions between metals and acids are always endothermic.
Water changes phases when heat is added or subtracted?
Boiling and melting are endothermic. Freezing is exothermic.
Why burning a candle is an exothermic reaction not endothermic?
The reaction releases heat and light to its surroundings, so it is exothermic.
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.
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.
When solid sodium hydroxide is added to water the solution gets hot is this endothermic or exothermic?
The hotness of water proves heat is absorbed by water so the process is exothermic which releases the heat and is absorbed by water.
When paint dries is it considered an exothermic reaction?
Yes, completely because there is no other chemical added to the paint to create a chemical reaction or to act as a internal catalyst.
Is the reaction of calcium chloride to ice a endothermic or exothermic reaction?
when CaCl2 is added to ice it becomes ionized slowly the ions become surrounded by water molecules the secondary types of bonding is responsible to evolve the heat so it is an exothermic reaction.
What happens to the temperature of a substance that is an endothermic reaction?
It will decrease as heat is removed from the environment and added to the products of the reaction.
