1.) What is the total pressure, in millimeters of mercury, of a gas mixture containing argon gas at 0.25 atm, helium gas at 350 mmHg, and nitrogen gas at 360 Torr?
2.) Your spaceship has docked at a space station above Mars. The temperature inside the space station is a carefully controlled 24 degrees Celsius at a pressure of 745 mmHg. A balloon with a volume of 425 mL drifts into the airlock where the temperature is -95 degrees Celsius and the pressure is 0.115 atm. What is the final volume, in millimeters, of the balloon if n does not change and the balloon is very elastic?
Please write out equtaion and steps
Calculate the hydronium ion concentration and the pH after the addition of 0.25 mL of 0.10 M HCl to each one. What accounts for the difference in the hydronium ion concentrations
The average concentration of bromide ion in sea water is 65 mg of bromide per kg of sea water. What is the bromide molarity if the density of seawater is 1.025 g/ml
a compound contain 60.87 carbon 4.38 hydrogen and 34.75 oxygen then determine its empirical formula?cof2carbonyl
Diet cola drinks have a pH of about 3.0, while milk has a pH of about 7.0. How many times greater is the H3O+ concentration in diet cola than in milk
For oxalic acid (HOOCCOOH) and citric acid (C3H4OH(COOH)3), plot a fraction of species vs pH curve, and create a pH vs volume curve, assuming that the titrant is a 1.00M NaOH solution. What indicators should be used for each endpoint?
Name a solvent for the following to dissolve in (hexane is nonpolar and water is polar): a.Glucose (polar) b.Lard (nonpolar) c.Vegetable oil (nonpolar)
Determine the fuel model (CnHm) and its probable name.- The percent mass composition of the fuel.- The percent of theoretical air used in the combustion.
Question- What name is given to the alpha substitution of a carbonyl compound where the electrophilic component is another carbonyl compound
Three 10.00mL samples of juice were titrated with DCP that had a standardized concentration of 1.01x10-3M. The three titrations took an average of 13.82mL of DCP. Calculate the mass (in mg) in 50.00mL of juice. (MM Ascorbic Acid = 176.124 g/mol)
A sample of an ideal gas at 1.00 atm and a volume of 1.89 L was placed in a weighted balloon and dropped into the ocean. As the sample descended, the water pressure compressed the balloon and reduced its volume.
A 10.00 mL aliquot of weak base is titrated with HCl. The equivalence point is reached after 17.21 mL of 0.4332 M HCl has been added. The pH is equal to 10.03 after 5.00 mL of HCl was added. Determine
4 liters of an ideal gas at 200 K is heated to 400 K. What is the gas's new volume assuming the number of moles and pressure remain constant
