Using a sample of gas where 2.0 atm is the pressure exerted by a gas while it has a volume =350 cm3 now you need to calculate What will be the volume of this gas sample at standard atmospheric pressure?
Consider the given equation: - hydrated salt BaX2·2H2O, where X = halogen. salt of 0.2650 g was dissolved in 200 ml of H2O and excess H2SO4 was added and get a mixture that was heated further and held at boiling for forty five min and 0.2533 g of the precipitate, barium sulfate, was filtered off, washed and dried you just need to identify the halogen, X in thi8s reaction?
The vapor pressure of pure acetone (propanone) is 266 torr. When a non-volatile solute is added, the vapor pressure of acetone above the solution falls to 232 torr. What is the mole fraction of the non-volatile solute in the solution?
What mass of sucrose should be combined with 514 g of water to make a solution with an osmotic pressure of 8.85 atm at 295 K? (Assume the density of the solution to be equal to the density of the solvent.)
Polycyclic aromatic hydrocarbons (PAHs) are a class of organic chemicals associated with the combustion of fossil fuels. Undeveloped areas may have total PAH soil concentrations of 5 µg/kg
what is the flow of the gulf stream in milliters per minute (b) what mass of water in the gulf stream flows past a given point in 24 hours? the density of seawater is 1.025 g/ml
The tabulated mass of Cl is 35.45 amu. The two dominant isotopes of naturally occurring Cl are 35Cl (34.97 amu) and 37Cl (36.97 amu).
Why do you suspect that 1-propanol is used as the reaction solvent (Base-Catalyzed Dehydrochlorination of 2-Chloro-2-methylbutane), rather than the more common ethanol
A weak monoprotic acid is exactly neutralized by 11.17mL of a standardized 0.1455M NaOH solution. If the Ka of the acid is 0.00084, what is the pH at the half-equivalence point.
