Is it better to have a higher yield or a lower yield in chemistry?

This depends on the application; if you need to produce a specific compound a higher yield is of course preferred.

Why could an actual yield be more than a theoretical yield?
If actual yield is higher than theoretical yield then it means the required products contains impurities.
Relationship between the concentration of reactants and the total number of collisions?
For any chemical reaction, there is a theoretical yield for the products. The theoretical yield is based on the balanced equation for that reaction. If any of the reactants is present at a lower amount, then your actual yield will be less than the theoretical yield.
What are the applications of analytical chemistry in industries?
Applications of chemistry in industries are vast and expansive. Chemistry is required for a wide range of industries such as cosmetics, nanotechnology, synthetic material, and the list goes on and on. The reality of the situation is that many new products whether it is a new drug or a new lubricant, the chances are that it was a product of new applications of chemistry.
How do you improve the yield of 4nitroveratrole?
add more excess agents to inc products. Adding more of the reagents increases the amount of product you will have, not increase your yield. To increase yield, you have to change conditions of the reaction mechanism, such as lowering the temperature to lower than 0C to avoid di-nitration.
How destructive is today's hydrogen bomb?
The most powerful hydrogen bomb ever built had a 50 megaton yield (USSR "Tsar Bomba" 1961), the most powerful hydrogen bomb ever built by the U.S. had a 20 megaton yield ("dirty" high yield warhead for the Titan ICBM, only tested in reduced yield 9 megaton "clean" version). The typical hydrogen bomb in stockpile today is only about 100 kiloton to 300 kiloton as it had been demonstrated that yields higher than this really have little practical military value and actually produce less damage than lower total yield in multiple weapons detonated at multiple locations across the target area.
What is percentage error in a chemistry experiment?
(actual yield-theoretical yield) / (theoretical yield)
What a chemistry word that starts with y?
yield
What is cut off yield?
what is cut off yield? ans. cut off yield is the rate at which bids are accepted. bids at yield higher than the cut off yield are rejected and those lower than the cut off are accepted. the cut off yield is set as the coupon rate for the security. bidders who have bid at lower than the cut off yield pay a premium on the security, since the auction is a multiple price auction.
Which is usually higher the actual yield or the theoreyical yield?
In my experience, the theoretical yield is usually higher, if everything is measured accurately.
Why is percentage yield important?
Percentage yield is purely for an economic view, you dont want to waste chemicals. purity is for reputation of a drug. impurities have negative effects and decrease potency of a drug.
Why the mild steel have two yield points?
Low carbon steels suffer from yield-point runout where the material has two yield points. The first yield point (or upper yield point) is higher than the second and the yield drops dramatically after the upper yield point. If a low carbon steel is only stressed to some point between the upper and lower yield point then the surface may develop Lüder bands.
How does chemistry contribute to energy research?
I don't know of any present research (I'm retired) but in the past, refining crude oil and developing the process known as catalytic cracking to get a higher yield of gasoline for fuel was a chemistry application to energy development. Chemistry was used to separate elements such as radium when the Curies discovered the element.
Why could an actual yield be more than a theoretical yield?
If actual yield is higher than theoretical yield then it means the required products contains impurities.
What is meant by the term micro cap stocks?
Micro cap stocks are generally those with a higher capital funding than other stocks. They typically are lower risk investments but may consequently produce a lower yield and return.
Colemans preferred stock is riskier to investors than its debt yet the yield to investors is lower than the yield to maturity on the debt Does this suggest that you have made a mistake?
Corporate investors own most preferred stock, because 70 percent of preferred dividends received by corporations are nontaxable. Therefore, preferred often has a lower before-tax yield than the before-tax yield on debt issued by the same company. Note, though, that the after-tax yield to a corporate investor and the after-tax cost to the issuer are higher on preferred stock than on debt.
Relationship between the concentration of reactants and the total number of collisions?
For any chemical reaction, there is a theoretical yield for the products. The theoretical yield is based on the balanced equation for that reaction. If any of the reactants is present at a lower amount, then your actual yield will be less than the theoretical yield.
Why do the theoretical and practical values differ?
Theoretical yield is what you have calculated to be your end result of product, usually in mass. Actual yield is what you experimentally were able to produce. Together they are used to determine percent yield.
