What type of reaction releases the most eneergy?
I guess that would be when a "regular" particle meets an antiparticle - in that case, 100% of the mass of both particles will be released as energy.Next come nuclear reactions, where usually something like a fraction of one percent of the matter gets released as energy. Chemical reactions release about a million times less energy than nuclear reactions.
A typical automobile engine converts only about 10 percent of chemical energy in gasoline into mechanical energy. Is this a violation of the law of conservation of energy?
yes
What are the isotopes in use in nuclear power plants and what reaction takes place?
Uranium is used as the feed fuel in nuclear power plants. Natural uranium contains 0.7 percent U235 but this is increased to about 4 percent for light water moderated reactors. The bulk of uranium is U238 and this is not productive, though some of it turns to plutonium during operation and this gives further energy output. The reaction with U235 and Pu239 is called fission, whereby the nucleus splits into two parts and releases energy
If two quantities are directly proportional when one quantity increases by 10 percent what does the other do?
increases by 10 percent increases by 10 percent increases by 10 percent
Thomas Edison said genius is one percent inspiration and 99 percent what?
Thomas Edison said genius is one percent inspiration and 99 percent perspiration.
To determine the formula of a new substance one of the first steps is to find?
The chemical formula is determined by chemical analysis of the components.
What is the importance of calculating percent yield of reaction?
to determine accuracy of a reaction to access how successful the reaction is to know the amount of material to be obtained if efficiency level is at 100%
Why is it important to determine the percent recovery of chemical reactions?
If the rate of reaction is too fast it can not be controlled. From a Health and Safety point of view this is dangerous. If the rate can be controlled by cooling for example, this would require adequate water (or other coolant ) control/flow. This would have to be taken into consideration at the plant design stage. This could involve a lot of extra cost. If the rate of reaction is too slow this could affect the whole process economics.
The ratio of the actual amount you isolate from a chemical reaction compared to the amount you could theoretically isolate is called the?
Percent Yield
Is emission of light evidence of chemical reaction?
ask a friend, family member, teacher, chemist, scientist, but i'm 37 percent sure no
Determine the percent yield of a reaction that produces 28.65g of Fe when 50g of Fe2O3 reacts with excess Al according to the following reaction Fe2O3 plus 2Al equals Al2O3 plus 2Fe?
81.93%
What is the theoretical percent yield?
Percent yield is a term that compares the amount actually produced in a chemical reaction versus how much could have been produced had all the reactants reacted fully. Theoretical percent yield is always 100%, because theoretically, all of the reactants reacted.
