Which of the following options give the correct relationships between the decimal prefixes? Select all that apply. Pay close attention to the sign and magnitude of exponent. -1 mL= 1x10^3 microliters -1GHz=1x10^6 Hz -10^3 kg=1 g -10^9 nm=1m -10ps=1x10^-13s
The haloform reaction is executed in this experiment to synthesize benzoic acid from a methyl ketone, acetophenone. Provide an explanation for the following steps in the procedure. a) Why is acetone added at the end of the reaction
If 164 mL of wet H_2 is collected over water at 24 C and a barometric pressure of 736 torr, how many grams of Zn have been consumed? (The vapor pressure of water is 22.38 torr.)
What mass of Aluminum is produced when 0.5 mole of Al2S3 is completely reduced with excess H2?
Maleic acid is a carbon-hydrogen-oxygen compound used in dyeing and finishing fabrics and as a preservative of oils and fats. In a combustion analysis, a 1.054- sample of maleic acid yields 1.599 of and 0.327 of.
A solution is prepared by mixing 250 mL of 1.00 M CH3COOH with 500 mL of 1.00 M NaCH3COO.
What mass of Fe will form when 63.0g of CO reacts with 145g of Fe2O3 according to the following equation? 3CO+Fe2O3->2Fe+3CO2.
an aqueous solution is prepared by diluting 3.30mL acetone, CH3COH3, (d= 0.789g/mL) with water to a final volumeof 75.0 mL. The density of the solution is 0.993 g/mL. what are the molarity and the molality of acetone in this solution?
What would you expect the measured decay rate to be 4.00 hours later? The half-life of Ru-97 is 2.79 days.
Identities of the components in a mixture by Gas chromatography may be determined by the technique called "spiking". Suppose you had run a chromatogram of your product and then deliberately added a known sample of 2 methyl 2 butene
Geologists can estimate the age of rocks by their uranium-238 content. The uranium is incorporated in the rock as it hardens and then decays with first-order kinetics and a half-life
A reaction is begun with a reaction mixture containing the following: [dye] = 1.0 x 10-4 M [bleach] = 0.10 M When [dye] = 8.0 x 10-5 M the rate is determined to be 3.74 x 10-7 M/min. When [dye] = 4.0 x 10-5 M the rate is determined to be 1.71 10-7..
