Not at all. Just be consistent with the units of both actual and theoretical yield.
In this case the yield is 77,27 %.
Theoretical yield is what would be if 100% of the reaction was complete and no amount of product was lost in any way, actually processes are not as efficient.This all depends on the accuracy of the one doing the experiment and on the reaction. Some reactions are reversible so less than 100% of the reaction goes to completion; other reactions do not go to completion because they require high amounts of energy or more time etc. Substances in the reaction can be lost during the procedure or be hard to separate from other parts of the experiment. In chemistry there is always an expected amount of error to a degree.The percent of error can be calculated with this formula:% error = (|actual yield - theoretical yield| / theoretical yield) x 100%
Yes, 12H2O do count toward theoretical yield of alum, since it is an integral part of alum formula. Otherwise it would be just K-Al double sulfate, with different structure.
Theoretical Chemistry
Theoretical yield is the theoretical amount of product possible to be created from particular amounts of reagent in a chemical reaction. The reaction itself, as well as the different components and complexity of steps, determine what a normal actual yield achieved will be. There are several reasons why theoretical yield is not generally (and I would speculate never) achieved. Firstly, it assumes ideal reaction conditions, such as standard temperature and pressure, which are not generally achieved or kept constant. Secondly, other reactions between chemicals might occur, or the reverse reaction might keep all the reagents from forming products. Lastly, the process by which the reagents are worked up to the final reaction, for instance measuring or purification, might result in a loss of reagent and thus change the amount of product you could actually get.
In this case the yield is 77,27 %.
because of variable in the situation '
"Better" is an interesting word. I would guess that theoretical MA beats actual MA any day of the week. Some energy is lost in friction.
the experimental % oxygen would be lower because there would be more KCL in the simple than oxygen
The shortest 'theoretical' air distance from Washington DC, USA to Manila, Philippines is 8572 miles. Actual distance would depend on airport location and actual route of the flight.
The atmosphere would be much more volatile.
There are 3 types of pour cost: 1) Theoretical PC, 2) Ideal PC, and 3) Actual PC. Theoretical cost refers to a theoretical or asking price, that you would like to get for a drink. It's the price that one would typically see on a drink menu. Ideal cost is the PC that you would get if you sold every ounce of liquor that was used, regardless of the selling price. Actual cost is the actual cost of selling the drink, which but includes waste, theft, etc. So the Pour Cost for liquor (or anything else) should be whatever the Ideal PC says it should be.

Theoretical probability = 0.5 Experimental probability = 20% more = 0.6 In 50 tosses, that would imply 30 heads.
Depending on whether you subtract actual value from expected value or other way around, a positive or negative percent error, will tell you on which side of the expected value that your actual value is. For example, suppose your expected value is 24, and your actual value is 24.3 then if you do the following calculation to figure percent error:[percent error] = (actual value - expected value)/(actual value) - 1 --> then convert to percent.So you have (24.3 - 24)/24 -1 = .0125 --> 1.25%, which tells me the actual is higher than the expected. If instead, you subtracted the actual from the expected, then you would get a negative 1.25%, but your actual is still greater than the expected. My preference is to subtract the expected from the actual. That way a positive error tells you the actual is greater than expected, and a negative percent error tells you that the actual is less than the expected.
What is the difference between practical and theoretical grammar? I am Russian , i would like to get to know about theoretical grammar more?
Well .9 in a % would be 90%, and .09 would be 9%. So I would say yes.
