Problem- What concluding statement can you make, on the basis of your observations regarding the fluctuations in pH for buffered and unbuffered solutions when small amounts of acid and base are added?
Your answer must be supported by illustrations, Please answer with work shown to receive points
Assuming the vinegar solution has a density of 1.01 g/ml calculate the percent by weight of acetic acid in your sample of vinegar. How does that value compare with 5 percent the value for the percent acetic acid in normal vinegar? I had 10.0ml of ..
Calculate the mass of water formed by the complete reaction of 758 g of propane (C3H8) with excess oxygen
A solution is 0.020 M in each Ca2+ and Cd2+. Adjusting the pH of the solution to which of the following values would achieve the best separation by precipitation of the hydroxides
If I have 2 mM of pyrene in decane, how do I make 10 uM, 0.5 mM, 1.0 mM, and 1.5 mM solutions using the density of decane (0.73 g/mL)
To find the mass of water use the density of water = 1.0 g/mL. I have looked at multipule different solutions that have already been worked but have not been able to get the correct answer no matter how many different ways i got about getting it.
The human eye is able to detect as little as 2.35 × 10-18 J of green light of wavelength 510 nm. Calculate the minimum number of photons of green light that can be detected by the human eye. Physical constants can be found here.
If all the species are at standard conditions except [H+], at what pH will this reaction have a potential of zero? The standard reduction potentials are 1.78 V for H2O2 and 1.36 V for Cl2.
At noon on a clear day, sunlight reaches the earth's surface at Madison, Wisconsin, with an average power of approximately 8.00 kJ·s-1·m-2. If the sunlight consists of photons with an average wavelength of 510.0 nm
What is the pH of a solution prepared by diluting 25.00 mL of 0.10 M HCl with enough water to produce a total volume of 100.00 mL
Problem- A rigid sealed steel container contains only acetone, in both the vapor and liquid phase. The temperature is 30 C. The mass of acetone in the system is 500 g . The volume in the system is 1.00 L.
Calculate the molar solubility of AgCl in a solution made by dissolving 10.0 g of CaCl2 in 1.50 L of solution.
A gas stream that contains 1.50 mole% CO2 flows through a pipeline. 20.0 kg/min of CO2 is injected into the line. A sample of the gas is drawn from a point in the line 10 meters downstream of the injection point and found to contain 2.3 mole% CO2.
