50 g of aluminum oxide is produced in the reaction of aluminum metal and oxygen gas at STP. How many liters of oxygen gas were reacted?
A small amount of the radioactive isotope Pb-212 was mixed with a small quantity of a non-radioactive lead salt containing 0.0100 g lead (Ar = 207).
Calculate the solubility (in M units) of ammonia gas in water at 298 K and a partial pressure of 9.00 bar . The Henrys law constant for ammonia gas at 298 K is 58.0 M/atm
Some sugar substitutes are made from derivatives of sucrose. SucraloseTM is a sweetener found in soft drinks and low-calorie foods such as yogurt.
How long would it take to electrodeposit all the Cu2+ in 0.200 L of 0.250 M CuSO4 solution with an applied potential difference of 0.270 V and a current of 3.55 amperes. Enter your answer in minutes.
A 36.4 L volume of methane gas is heated from 25 degrees celcius to 88 degrees celcius at constant pressure. What is the final volume of the gas?
Many drugs are high-molecular-weight amines that are weak bases. Such amines are not soluble in water, which limits the ways they can be administered and means that they are not soluble in body fluids such as blood plasma and cerebrospinal fluid
A 2.983 gram sample containing an unknown amount of arsenic trichloride and the rest inerts was dissolved into a NaHCO3 and HCl aqueous solution. To this solution was added 1.910 grams of KI and 50.00 mL of a 0.00894 M KIO3 solution.
Phosgene decomposes by the reaction COCL(g) CO(g) + Cl2 K2=8.3x10^-4 (at 360C) When 5.00 of COCL2(g) are placed in a 10.0 L flask, find the quilibrium concentration of COCL2, CO and CL2 using the follow steops
Fructose contains only C,H, and O. 17.1g of carbon dioxide gas and 7.26 g of water vapor were produced when 12.1 g of solid fructose were combusted with excess of oxygen gas.
What is the pH of a solution resulting from the addition of 11.9 mL of 0.20 M HCl to 50.0 mL of 0.12 M NH3? Assume the volumes are additive. Kb of NH3 = 1.8 10-5.
