You are able to carry a maximum of 35 kg. What is the maximum volume of aluminum that you can carry? (Al has a density of 2.7 g/cm3)
The experiment involves reactivities of alkyl halides. Explain what is the soluble product of reaction between silver nitrate as well as 2-bromo-2-methylbutane. Is this a SN1 or SN2 reaction-explain
You are given the masses, in grams (g), and the volumes, in cubic centimeters (cm3), for a series of substances. Arrange them in order of increasing density(Lowest to Highest)
A chemist places 1.7823 g of Na2SO4 in a 100 mL volumetric flask and adds water to the mark. She then pipets 10 mL of the resulting solution into a 50 mL volumetric flask and adds water to the mark and mixes to make a solution.
The nuclide 241Am decays with a half life of 458 yrs. If the activity of 241Am in the detector is 3*10^4 Bq, calculate the mass of 241Am present.
Many power plants produce energy by burning carbon-based fuels, which also produces carbon dioxide. Carbon dioxide is a greenhouse gas, so over-production can have negative effects on the environment.
which one of the liquids would you expect to have the lowest vapor pressure at room temperature?
What pressure would have to be applied to a 28.0mL sample of gas at 25°C and 1.00atm to compress its volume to 10.0mL at constant temperature?
Isoprophyl alcohol has a vapor pressure of 90 mm Hg at 40C. If its normal boiling point is 335 K, what is the vapor pressure of isopropyl alcohol at its normal boiling point
A 347 mL container holds 0.146 g of Ne and an unknown amount of Ar at 35°C and a total pressure of 630. mmHg. Calculate the moles of Ar present.
four beakers containing potassium nitrate dissolved in water are allowed to evaporate to dryness. beakers 1 through 4
what is the pressure when the volume of the gas is reduced to one-fifth of the original value at the same temperature?
Explain if a solution of compound S (MW = 200) w a known ε of 20,000 at λmax of 300 nm gave an absorbance of 1 in 1cm cell, explain how many mg of compound S was present in 1 mL of the analyzed solution
