A 100ml sample of sodium bromide containde co104.62g of sodium bromide. upon evaporation, 6.280g of reside was obtained. frome this data calculate each of the folowing for the solution;
a density of the solution
b percent by mass of sodium bromide in the solution
concentration of sodium bromide in grams per 100ml of water.
D grams of sodium bromide per liter of solution
E molarity of the solution
Compute the moment of inertia of the molecule in kg m 2 . And also determine the greatest wavelength of the radiation that can excite the molecule into rotation.
Indicate what precipitates, if any, form when solutions of each of the following are added to a solution containing the Group I cations.
To eliminate heating the bodies of water surrounding the power plant, the evaporation of the coolant water is what cools the steam; the water vapor generated by this evaporation is released to the atmosphere
A sample of propane,C3H8, contains 13.4 moles of carbon atoms. How many total moles of atoms does the sample contain?
Fundamentals of acids and bases - Water self ionizes to a small extent creating equal concentrations of hydronium and hydroxide ions. Find the molar concentration of these ions in water at 25 o C?
What hybridization would you expect for the indicated (bold) atom in each of the following molecules?
A compound contain 60.87% carbon, 4.38% hydrogen, and 34.75% oxygen then determine its empirical formula?
Titrations: Finding Mass Percent of Arsenic in a Pesticide, The arsenic in a 1.0211-g sample of a pesticide was converted to H3AsO4 by suitable treatment. The acid was then neutralized and exactly 40.00 mL of 0.05922M
Begin your explanation by identifying the intermolecular forces of attraction of the solute and the solvent.
Ammonia will react with oxygen in the presence of a copper catalyst to form nitrogen and water. From 164.5°C to 179.0°C, the rate constant increases by a factor of 4.27. What is the activation energy of this oxidation reaction?
Which of the following are a conjugate acid-base pair in the above reaction?
Suppose that Mt=Lt=0.1M (exactly) and the pH is somehow fixed at 5.00. (This means that the charge balance no longer applies.) Use the equilibria and the two mass balances to find the concentrations of ML+, M+2, L-, HL.
