If 15.4 g of CO2 was produced from the thermal decomposition of 39.37 g of CaCO3 then what is the percentage yield of the reaction?
To find the percentage yield, you first need to calculate the theoretical yield of CO2 that would be obtained from the given mass of CaCO3. Then divide the actual yield of CO2 (15.4 g) by the theoretical yield, and multiply by 100 to get the percentage yield. The percentage yield is calculated as (actual yield / theoretical yield) * 100.
If a student used 1.34 g of silver to produce silver nitrate and the actual yield was 2.01 g how do you calculate the percentage yield show the steps?
Percentage yield = (actual yield / theoretical yield) x 100. Theoretical yield of silver nitrate can be calculated using stoichiometry based on the reaction involved. In this case, divide the actual yield (2.01 g) by the theoretical yield (calculated from the balanced chemical equation) and multiply by 100 to get the percentage yield.
Calculate the percent yield of chlorine gas in the decomposition of hydrochloric acid if 25.8 grams of hydrochloric acid produces 13.6 grams of chlorine gas?
Percent yield can be calculated using the formula: (actual yield / theoretical yield) x 100. First, determine the theoretical yield of chlorine gas by finding the molar ratio between hydrochloric acid and chlorine gas. Once you have calculated the theoretical yield, plug the values into the formula to find the percent yield.
What is the percent yield for the reaction if 65.0 g of iron lll oxide produces 15.0g of iron?
Percent yield is calculated by dividing the actual yield by the theoretical yield and multiplying by 100. The theoretical yield can be calculated by stoichiometry. In this case, the theoretical yield of iron would be 43.3g. Therefore, the percent yield would be (15.0g / 43.3g) x 100 = 34.6%.
What happens when ethanol is mixed with vinegar?
Probably nothing since vinegar is a dilute concentration of acetic acid...However if you had pure acetic acid & ethanol the two would react to form an ester called ethyl acetate at room temperature: CH3CH2OH (ethanol) + CH3COOH (acetic acid) <==> CH3COOCH2CH3 (ethyl acetate) + H2O However since it is an equilibrium reaction you'd have a mixture of the products & reactants & would need to separate the mixture. Under the presence of an acid catalyst (such as sulfuric acid) & continuously removing the water you can increase the yield of ethyl acetate.
Can meloxicam yield a positive result on ANA testing?
can taking meloxicam yield a positive result on antinuclear antibody (ANA) test
All amino acid having an aromatic ring give a positive xanthoproteic test under identical condition?
No, not all amino acids with an aromatic ring give a positive xanthoproteic test. The xanthoproteic test is mainly positive for amino acids containing aromatic rings with phenolic groups such as tyrosine and phenylalanine. Aromatic amino acids like tryptophan do not give a positive xanthoproteic test under identical conditions.
What color develops when ninhydrin react with amino acids?
These are the amino acids that will yield positive result to the ninhydrin test: Non-polar amino acids: Glycine, Alanine, Valine, Leucine, Isoleucine, Phenylalanine, Methionine, Tryptophan Polar Neutral Amino acids: Serine, Cysteine, Threonine, Asparagine, Glutamine, Tyrosine Polar Acidic Amino Acids: Aspartic acid and Glutamic acid Polar Basic Amino Acids: Histidine, Lysine, Arginine
What amino acid will yield a positive result with millon's test?
Tyrosine. Millon's Reagent-a solution that is usually made by dissolving mercury in concentrated nitric acid and diluting with water and that when heated with phenolic compounds gives a red coloration used as a test especially for tyrosine and proteins containing tyrosine. (from merriam-webster's medical dicitonary) i hope this will help you.
What does hydrolysis of a simple protein yield?
Amino acids.
What is the result of hydrolysis of a dipeptide?
Hydrolysis of a dipeptide results in the breaking of the peptide bond between the two amino acids in the dipeptide to yield two separate amino acids. This process requires the addition of water to break the bond, resulting in the separation of the amino acid components.
What is x divided by negative nine?
X divided by negative nine is expressed mathematically as ( \frac{x}{-9} ) or ( -\frac{x}{9} ). This represents a value that is the result of taking ( x ) and dividing it by negative nine, which will yield a negative result if ( x ) is positive, and a positive result if ( x ) is negative.
How do you convert c6h5nh2 to c6h5ococh3?
To convert aniline (C6H5NH2) to phenyl acetate (C6H5OCOCH3), you can follow these steps: First, acetylate aniline using acetic anhydride or acetyl chloride, which will replace the amino group with an acetyl group, forming acetanilide (C6H5NHCOCH3). Next, you can hydrolyze the acetanilide with an acid or base to yield phenyl acetate. This process involves replacing the amine group with an ester group, ultimately giving you C6H5OCOCH3.
Why do negative and negative become positive?
A negative and a negative can yield a positive result in some cases.SubtractionSubtracting a negative number is the same as adding its negative value, which is positive. So if the subtracted number is larger in value, the answer will be positive.(-4) - (-3) = (-4) + 3 = (-1) * the subtracted number was not large enough(-4) - (-8) = (-4) + 8 = 4 *the subtracted number was large enough to yield a positiveMultiplication and DivisionWhenever a negative number and a negative number are multiplied or divided, the negative signs "cancel out" and the result is positive.(-2) x (-3) = 6(-6) / (-3) = 2A multiplication or division involving one negative and one positive will, however, have a negative result.
How do you prepare ethyl methyl ketone from calcium acetate?
Ethyl methyl ketone can be prepared from calcium acetate by reacting it with barium hydroxide to form barium acetate, which can then be treated with sulfuric acid to yield ethyl methyl ketone. The ketone can be further purified by distillation.
Sodium acetate from glacial acetic acid?
To prepare sodium acetate from glacial acetic acid, you can first neutralize the glacial acetic acid with sodium hydroxide. The reaction will yield sodium acetate and water. Afterward, you can evaporate the water to obtain solid sodium acetate crystals.
What combination of signed numbers always leads to a positive number?
If I understand the question correctly, the sum of two positive numbers will *always* yield a positive number. The product of two positive or two negative numbers will always yield a positive number. The division of two positive or two negative numbers will always yield a positive number. There are more examples along this line. I am not sure if this is what you wanted to know.
