Student collects 47.56mL of hydrogen gas over water at a temp of 22C. The atmospheric pressure is reported to be 29.78 in Hg. I have found that atmospheric pressure in mmHg is 756.412, and the vapor pressure of water at 22C is 19.827 mmHg. a. what is the pressure of dry H2 in mmHg? and in atm? Assuming the ideal gas behavior, how many moles of H2 gas were collected?
What is the strongest base that may exist in water. What happens to stronger bases
Assume that the partition coefficient, K, for partitioning of compound A between diethyl ether and water is 3; that is, A preferentially partitions into ether.
what an alkane with molecular formula C8H18 gives a single product of monohalogenation?
61.0 mL of a 1.70 M solution is diluted to a volume of 268 mL. A 134-mL portion of that solution is diluted using 119 mL of water. What is the final concentration
A 397 mL container holds 0.146 g of Ne and an unknown amount of Ar at 35°C and a total pressure of 639 mmHg. Calculate the moles of Ar present
Write a balanced equation for each of the two steps of the reaction, namely: (1) the reaction between benzyltriphenylphosphonium chloride and sodium hydroxide
raising the total pressure from P0 (the initial air pressure) to P1 (the total final pressure of H2(g) + air).Compose an algebraic expression for the volume (V2) that this sample of H2(g) would occupy if it were isolated
Consider the following equilibrium process at 686°C: CO2(g) + H2(g) ? CO(g) + H2O(g) The equilibrium concentrations of the reacting species.
Consider one mole of a monatomic ideal gas at 300 K that udergoes a free expansion from a volume of 1m^3 to 10 m^3. a). How much does the chemical potential of each molecule in the gas change?
What type of hybridization is used on the central atom in CHCL3?
Why must the free-radical polymerization reaction be heated when it is not necessary to heat the ionic polymerization
calculate the change in ph when 6 ml of 0.1 M HCl is added to 100 ml of a buffer solution that is 0.1 M in NH3 and 0.1 M in NH4Cl. And calculate the change in PH
