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).
What type of reaction is CH4 plus 2O2 equals CO2 plus 2H2O plus 218kcal?
exothermic
What type of reaction is 2N2O5 plus NO 4NO?
CH4 + 2O2 📷 CO2 + 2H2O + Heat
Does CO2 (g) plus H2 (g) H2O (g) plus CO (g) represent an enthalpy of formation?
This is an exothermic reaction.
What are differences between endothermic and exothermic reactions examples?
The main differences between exothermic reactions and endothermic reactions are: Exothermic reactions are reactions that give off energy (light, electrical or mainly heat), causing the surroundings to warm up. Endothermic reactions are reactions that absorb energy, causing the surroundings to cool down. The products of an exothermic reaction have less energy, or less total enthalpy, than of it's reactants. This is due to the reactants containing more stored energy because energy from external sources is not required. This also gives the products more stability because in order to achieve a reversible reaction and break the chemical bonds of the products, you will need to apply more energy to it. The opposite is for endothermic reactions. The products of the reaction have a greater total enthalpy of the reactants, causing the reactants stored energy to decrease. This produces less stable products that need less energy to break their bonds in a reversible reaction. Finally most exothermic reactions are spontaneous, where as most endothermic reactions are not spontaneous as they generally need energy applied to them before they start.
Is the metabolism of carbohydrates endothermic or exothermic?
Exothermic. Carbohydrates + oxygen (from respiration) yields CO2, H2O and heat.
Is the breakdown of glucose endothermic or exothermic?
Exothermic. Glucose is one of the major source of energy of the body and can only act as an energy source because its breakdown into CO2 is an exothermic reaction.
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).
What is the reaction of sodium bicarbonate and hydrochloric acid is endothermic or exothermic?
Neutralisation reaction will take place. HCl + NaHCO3 ---> NaCl + H2O + CO2
What has primarily ionic bonding na2o3 na2o co2 ccl4?
Na2o
What type of reaction is CH4 plus 2O2 equals CO2 plus 2H2O plus 218kcal?
exothermic
Which compounds is not ionic Nal CaCl2 CO2 Na2O?
CO2
Does heating calcium carbonate produce an endothermic or exothermic reaction?
its an endothermic reaction, because the it broke the bonds of the calcium carbonate (CaCO3) in order to make calcium oxide (CaO) and Carbon dioxide (CO2).
What type of reaction is 2N2O5 plus NO 4NO?
CH4 + 2O2 📷 CO2 + 2H2O + Heat
Is Na2CO3 H2O endothermic or exotermic reaction?
If formed out of elements C + O2 it is exothermic (heat, fire); But as degradation of complex compounds it depends on the compound used and other product formed, but a lot of degradations are endothermic (needs high temperatures and stops after heating is stopt, it cools 'itself' down)
Does CO2 (g) plus H2 (g) H2O (g) plus CO (g) represent an enthalpy of formation?
This is an exothermic reaction.
Why sodium carbonate decomposed?
The reaction is:Na2CO3--------------Na2O + CO2
