A cylinder is filled with 10.0L of gas and a piston is put into it. The initial pressure of the gas is measured to be 295.kPa. The piston is now pushed down, compressing the gas, until the gas has a final volume of 5.90L. Calculate the final pressure of the gas. Be sure your answer has the correct number of significant digits.
What happens to the interference pattern that results from the diffraction of electrons passing through two closely spaced slits if the rate of electrons going through the slits is decreased to one electron per hour
What is the electron configuration of a third period element that forms an ion with a -2 charge
the critical temperature of the mixture is known to be 200 F. Compare your answer with the critical pressures of pure methane and pure n-hexane.
Calculate the volume of 1M solution of HCL needed for 1 unit shift of the pH of the following solutions: A. 100 mL of 0.01 M solution weak acid (pKa = 6) and 0.05 M of its sodium salt
The problem though is that Schaum's doesn't give an explanation for why they got that answer without merely stating to use the quadratic formula to solve it.
Problem- Calculate the change in pH when 7.00 mL of 0.100 M HCl(aq) is added to 100.0 mL of a buffer solution that is 0.100 M in NH3(aq) and 0.100 M in NH4Cl(aq). Calculate the change in pH when 7.00 mL of 0.100 M NaOH(aq) is added to the original..
The lowest molecular weight on the list of unknowns is formic acid, MW = 46.03 g/mol. Your titration volume should be between 10 mL and 50 mL. What is the smallest and largest masses of formic acid that would give titration volumes within these li..
2NOCl(g) → 2NO(g) + Cl2(g) ,At 450 K the rate constant is 15.4 atm-1s-1. How much time (in s) is needed for NOCl originally at a partial pressure of 46 torr to decay to 25.8 torr.
State the name of the major organic product produced when 2-methylpropanoyl chloride react with3-methylbutanoic acid in the presence of the weak base, pyridine
If a closed "piston-container" of water and CO2 gas were warmed, and the volume were expanded, what would be the expected change in solubility of the gas
Explain how many liters of O2 gas measured at 807torr and 250.0°C are formed by the decomposition of 253 g of KClO. You will need a balanced equation where KClO is the reactant. The other product is KCl.
Draw the Lewis structure for H2SeO3 from the skeletal template structure below. If the valence shells are filled to the usual limit (maximum of 8), how many non-bonding valence electrons are there in the molecule?
