What mass of O2 does the tank contain. kg (b) What volume would the gas occupy at STP? L (c) At what temperature would the pressure in the tank equal 150. atm
When a 18.5 g piece of copper originally at 99.5C is placed in 58.5 g of water at 24.0C, the temperature of the water rises to 26.1C. If the specific heat of water is 4.180 J , calculate the specific heat of copper. can you show work and the anser..
A cylinder of compressed gas rolls off a boat and falls to the bottom of a lake. Eventually it rusts and the gas bubbles to the surface. A chemist collects a sample of the gas with the idea of trying to identify the gas.
a gas occupies a volume of 458 mL at a pressure of 1.01kPa abd temperature of 295 K. When the pressure is changed, the colume becomes 477 mL. If there had been no change in temperature, what is the new pressure?
Calculate the pH of a buffer solution that is 0.250 M in HCN and 0.170 M in KCN. For HCN, Ka = 4.9 x 10^-10 (pka = 9.31). Use the equilibirum approach to calculate this pH
The sum of the substituent positions do not add up to lowest possible number. -The double bond in the ring does not contain the number one carbon. -Molecule has no cis-trans isomers. -The wrong name for the benzene derivative is used
A solution of .312 M KOH is used to neutralize 15.0 mL of a .186 M H3PO4 solution. what volume, in milliliters, of the KOH is required to reach the endpoint. H3PO4(aq)+3KOH(aq)>K3PO4(aq)+3H2O(l)
A solution is prepared by mixing 4 ml of .20 M NH3, 1 ml of .20 M HCl, and 5 ml of water. Calculate the concentration of NH3 and NH4+ in the final diluted solution.
find the of X-281, you prepare a 0.075 test solution of X-281. The pH of the solution is determined to be 3.00. What is the of X-281?
