When choosing unknown organic substances which are critric acid, acetone, urea, benzaldehyde, glycerol, and MTBE Write one or two paragraphs summarizing this experiment of properties of organic substances and see what results they got using the numerical data obtained and calculated to support the claims.

a Assume that mitochondria are cylinders 8.00 um in length and 0.800 pm in diameter. What is the volume of a single mitochondrion? The volume of a cylinder is given by the expression: V = n x y2 x h Volume= m

The mass of magnesium used in this experiment is critical to determining the moles of hydrogen gas generated. The analytical balances used in Chemistry 1A labs are very sensitive to point that touching materials with your fingers before measuring them can affect the measurements. The balances are sensitive enough to detect dirt and oils from your fingers transferred to the magnesium. Would your experimental value of R increase or decrease if the mass of magnesium measured was artificially high due the touching it with your hands? Increase Decrease

A model for the compound 2,3-dimethyl-2-butanol is shown. ball & stick C- + labels [Review Topics] [References] Use the References to access important values if needed for this question. Write a balanced chemical equation that shows the formation of 2,3-dimethyl-2-butanol from the elements carbon (C), hydrogen (H₂), and oxygen (0₂). (Use the smallest integer coefficients possible and do not include states. Enter the elements in the order: C, H, then O in the product box.)

(Incorrect) An impure sample of hydrocarbon having a total mass of 41.0 g undergoes combustion analysis to generate 82.6 g CO₂(g) and 16.9 g H₂O(g). Assuming that the impurities do not contain carbon or hydrogen, what percentage of the initial sample is the pure hydrocarbon? Provide the numerical value of your response in decimal notation rounded to 3 significant figures. You answered: 4.58 The correct answer is: 59.5%

Jset2_5zKMTIDEhEBBQc5Ge4YwKAkK5h... O CHEMICAL REACTIONS Solving for a reactant using a chemical equation Ammonium perchlorate (NH CIO,) is the solid rocket fuel used by the U.S. Space Shuttle. It reacts with itself to produce nitrogen gas (N,), chlorine gas (Cl,), oxygen gas (0,), water (H,O), and a great deal of energy. What mass of water is produced by the reaction of 2.59 g of ammonium perchlorate? Be sure your answer has the correct number of significant digits.

1.064g of an organic compound containing carbon and hydrogen was analyzed by combustion analysis and mass spectrometry. 3.339g of carbon dioxide and 1.367g of water vapor were produced when the sample was combusted. Mass spectra data determined the molar mass of the sample to be 56.1g/mol What is the compound's molecular formula? Enter a number in each space. Answers must be numerical - for example, enter "1" not "one".

High-density lipoprotein (HDL) cholesterol is the "good" cholesterol because adequate levels reduce the risk of heart disease and stroke. HDL levels between 40. and 59 mg/dL are typical for a healthy individual. What is this range of HDL cholesterol in units of mol/L? The formula for cholesterol is C27H46 O. Range of HDL cholesterol is between and mol/L.

Nitroglycerine is a shock-sensitive compound that decomposes as follows:  2 C3H5N3O9(l)     -->     6 CO2(g)   +  3  N2(g)   +   ½ O2(g)   +   5 H2O(g) 10.0 kg of nitroglycerine sits in a 5.0-L cylinder.  A chemist, angry that an experiment didn’t work, foolishly kicks the cylinder, thereby inadvertently performing his last and most dramatic experiment.  The final temperature of the product mixture is 595 oC.  Assume ideal gas behavior and complete decomposition.  Calculate the total pressure (atm) in the cylinder the moment before the explosion.

Q5. As part of the aspirin synthesis lab, the orgo students also had to perform the following calculation to demonstrate their knowledge. Are you able to help them work this out?Saponification is a process in which soap is produced from the chemical reaction between animal fat (triglycerides) and a strong base such as NaOH. An example of such a balanced chemical reaction is shown here:C57H110O6 + 3NaOH à C3H5(OH)3 + 3C18H35O2NaIf, during the saponification reaction, 228.5 g of C57H110O6 is mixed with 211.7 g of NaOH and 180 g of soap is produced: a. Calculate the theoretical yield of soap (in grams), C18H35O2Na, and indicate which species is the limiting reactant. Provide your answer to 2 decimal places. b. Calculate the percent yield for this reaction. Provide your answer to 1 decimal place. Show ALL steps and equations involved in your calculations. Remember to label all steps clearly and use appropriate units
