A 2.0-liter sample of H2(g) at 1.00 atm, an 8.0-liter sample of N2(g) at 3.00 atm and a 4.0-liter sample of Kr(g) at 0.50 atm are transferred to a 10.0-liter container at the same temperature. Calculate the partial pressure of each gas and the total final pressure in the new container.
Consider the reversible reaction: A(g) 2B(g) At equilibrium, the concentration of A is 0.381 M and that of B is 0.154 M. What is the value of the equilibrium constant, Keq?
Rank them in order of size from largest to smallest. In this diagram, A and B are different palindrome sequences on a DNA strand. Only the restriction enzyme that recognizes site B is present. Explain why only two fragments would be produced. How ..
Find the heat transferred (in kJ) when 5.55 L of ethylene glycol (d = 1.11 g/mL) in a car radiator cools from 40.0°C to 25.3°C.
The sample is diluted with 72.178 g of water. A 14.024 g aliquot of this solution is then titrated with 0.1097 M HCl. It required 29.55 mL of the HCl solution to reach the methyl red endpoint. Calculate the weight percent NH3 in the aqueous waste.
A water sample contains 118mg/L of bicarbonate ion, 19mg/L of carbonate ion, and has a pH of 9.5. What is the alkalinity of this water expressed as mg/L of CaCO3
A 4.10 g nugget of pure gold absorbed 278 J of heat. What was the final temperature of the gold if the initial temperature was 25.0°C? The specific heat of gold is 0.129 J/(g·°C).
What is the silver ion concentration in a solution prepared by mixing 419 mL of 0.391 M silver nitrate with 457 mL of 0.417 M sodium carbonate. The Ksp of silver carbonate is 8.1 × 10-12
Assume that you have an aqueous solution of an unknown salt. Treatment of the solution with dilute NaOH, Na2SO4, and KCl produces no precipitation. Which of the following cations might the solution contains
If a pure R isomer has a specific rotation of -133.0°, and a sample contains 64.0% of the R isomer and 36.0% of its enantiomer, what is the observed specific rotation of the mixture
Balance the equation using the smallest possible integers. Also determine the sum of the coefficients of the reactants?
Explain this theary and how the shapes of simple molecules and polyatomic ions can be worked out using it. you will need to illustrate your account with a number of diagrams, in particular showing the difference typical shapes of simple molecules ..
