An exothermic (exoergic) nuclear reaction is areaction that releases energywhile an endothermic (or endoergic) reaction is one that requires an input of energy to take place. ... If the reaction energy is positive, the reaction is exothermic but if the reaction energy is negative, the reacti...
What is spectrophotometry? What is a halohydrin? (a) What is rubber? (b) What is vulcanization? (c) What is the purpose of vulcanizing rubber? Why would a polystyrene cup be used in an exothermic reaction between HCl and NaOH instead of a beaker?
What is thermodynamics in chemistry? Understand thermodynamics definition, systems and surroundings, and endothermic and exothermic reactions in chemistry. Discover the principles of thermodynamics. Related to this Question Explore our homework questions and answers library ...
Why hydrazine is used as a rocket fuel? Hydrazine is used as a rocket fuel because it reacts very exothermically with oxygen to form nitrogen gas and water vapor. The heat released and the increase in number of moles of gas provide thrust. ... The combustion of hydrazine is an exothermic...
A flame (from Latin flamma) is the visible, gaseous part of a fire. It is caused by a highly exothermic chemical reaction taking place in a thin zone. Fire A rapid, persistent chemical change that releases heat and light and is accompanied by flame, especially the exothermic oxidation of ...
Exothermic vs. Endothermic Here is how to classify the phase changes as endothermic or exothermic: Phase Change Name:Freezing •Phase: Liquid to solid •Energy Change: Exothermic •Example: Freezing water Phase Change Name:Melting •Phase: Solid to liquid ...
Biodiesel is a convenient fuel but I suspect running a tractor on pure methanol would give a higher EROEI, since the lipid-alcohol to ester reaction is exothermic and additional energy must be supplied to recover any excess methanol (if that is not to be totally wasted by venting). ...
What is the product of the reaction given below? What is the product of the reaction given? Identify what occurs in the reaction shown below. What type of chemical reaction is the opposite of synthesis? What happens to the energy release of an exothermic reaction?
What types of reactions are always exothermic? Two chemicals react in an endothermic reaction. What can be known about this reaction? What is the reverse of a combustion reaction? What product(s) would you expect to obtain from each of the following reactions given below: ...
