Nuclear engineers use chlorine trifluoride in the processing of uranium fuel for power plants. This extremely reactive substance is formed as a gas in special metal containers by the reaction of elemental chlorine and fluorine. This is the reaction:
______Cl2(g) + ____ F2(g) + _____ ClF3(g)
When this reaction is run with 53.3 g of Cl2 and 114.0 grams of F2, what mass of chlorine trifluoride will be prepared?
A 4.000-g sample of the metal nitrate M(NO3)2 was dissolved in water and treated with excess aqueous sodium sulfate. The sulfate salt that formed weighed 3.318 g. Determine the identity of the metal.
A 255-mL sample of HCl solution reacts with excess Mg to produce 14.0 L H2 gas at STP. What is the molarity of the HCl solution?
A mixture of sand and iron pieces weighs 53.29 g. Using a magnet, the iron is removed and weighs 15.63 g. What is the percent composition of sand in the mixture?
What mass of solid sodium fluoride (molar mass = 41.99 g/mol) should be added to 1.0 L of 0.23M hydrofluoric acid to make a buffer with a pH of 2.94? (Ka of HF = 1.36 x 10-3)
Two of the following ions depend on their conversion into a gas for detection. What are the 2 ions? The two ions will form an ionic compound.
Calculate the pH of a solution resulting from the titration of 50mL of 0.033M HBr with 25 mL of 0.117M KOH. Give your answer to two decimal places.
The concentration fo certain sodium hydroxide solution was determined phthalate(abbreviated as KHP). KHP is an acid with one acidic hydrogen and a molar mass of 204.22 g/mol.
A lactic acid/lactate ion buffer solution contains 0.29 M HC3H5O3- and 0.80 , respectively. The Ka value of lactic acid is 1.4x10^-4. Calculate the pH of the buffer.
What is the concentration of [Cl?] in a solution of 10 mL of 12 M HCl when 6 mL of water is added?
From the ration of the mass of the black product to the initial 5g placed in the flask, could the remaining black compound be the anhydrous copper carbonate hydroxide molecule?
If 76.0 mL of .150 M HCL is needed to neutralize all the NH3 from a 2.25-g sample of organic material, calculate the mass percentage of nitrogen in the sample.
A solution of ethanol (C2H5OH) in water is prepared by dissolving 57.0 mL of ethanol (density = 0.79 g/cm3) in enough water to make 255.0 mL of solution.
