How could you use the principles of stoichiometry when preparing food in the kitchen? What are some examples of how stoichiometry is used to manufacture products found in your home?
Please answer in 150 words min.
What would you expect to observe in terms of the angle of rotation if you were to double the concentration of a sample, but kept all other variables constant?
How many grams of TiCl4 are needed for complete reaction with 155L if H2 at 430 degrees C and 780mmHg pressure? How any liters of HCl gas at STP will result from the reaction described in part (a)?
A solution containing 0.2 g/mL of a pure R enantiomer in a 1 dm polarimeter rotates plane polarized light by +3 degrees. What is the specific rotation of the R isomer. What will be the specific rotation of its S isomer
Describe your experiences as a reader. When did you learn to read when you were young? What do you remember about that process? Would you describe yourself as a "reader"?
Still on Le Chatelier's principle, Ketones are known to be less reactive in aldol condensations.
How many liters of HCl (g) measured at STP can be produced from 6.94 g of Cl2 and excess H2 according to the following balanced equation?
Upon reaction with excess sulfamic acid, HSO3NH2, a 0.121g sample of a mixture of sodium nitrite, NaNO2, and sodium chloride, NaCl, produced 28.3 mL of nitrogen gas collected over water at 25.3 degrees Celsius and at a barometric pressure of 738 m..
Problem- A 12 fl oz can of Coors Light is labeled as having 4.2% alcohol content. (Note this is % volume, also written as v/v%). Considering that ethanol (C2H60) is the alcohol used, what is the molarity of ethanol in one can.
Calculate the pH of a dilute solution that contains a molar ratio of potassium acetate to acetic acid (pKa = 4.76) of 5:1? Enter answers with 2 decimal points.
from the plots of the boiling point versus the volume of distillate in either of the fractional distillations of the ethanol-water mixture,what conclusion can you draw about the homogeneity of the distillate?
What is the heat capacity of the bomb?(Assume that the quantity of water surrounding the bomb is exactly 2250 g).
As a reference, a standard mixture containing 2.26 micrograms Co/mL and 1.92 micrograms Ti/mL was prepared and measured to have a signal-to-signal ratio of 2.41 Ti: 1.00 Co.
