The compound known as butylated hydroxytoluene, abbreviated as BHT, contains carbon, hyrdrogen, and oxygen. A 2.626 g sample of BHT was combusted in an oxygen rich environment to produce 7.867g of
CO2(g) and 2.576g of H2O(g).
During the laboratory exercise you will need 100.00mL of a 0.20M Ni^+2 solution and 25.00ml of a 0.10M Co^+2 solution. You will prepare the Ni^+2 solution from solid NiSO4 (X) 6H20 and the Co^+2 solution from solid Co(NO3)2 (X) 6H20
Compare this temperature with the true boiling point of N2. The boiling temperature is the temperature at which the areas under the two van der Waals loops are equal. In order to solve the problem
Prepare 1.00L of a pH~12 buffer with a total phosphate concentration of 0.050 M.You have at your disposal the following compounds
What is the molar solubility of Hg2C2O4 (Ksp = 1.75x10^-13) in 0.34M Hg2(NO3)2
The solubility of barium fluoride, BaF2, is 3.15 x 10-3 M at 25 °C. Calculate the solubility product, Ksp, of both compounds.
A solution is prepared by dissolving 0.11 mol of acetic acid and 0.11 mol of ammonium chloride in enough water to make 1.0 L of solution. Find the concentration of ammonia in the solution.
how is the rate of consumption of O2 related to the rate of consumption of NH3 in the reaction 4NH3 + 5O2 -->4NO +6H2O?
If the initial concentration of cyclopropane is 0.150 M, what will the concentration of cyclopropane be after 22.0 hours? b) What is the half-life for the conversion process?
what is the molar mass of the acid? If the standardization of the NaOH solution, why is it important to rinse the wet pipet with small portions of the standard oxalic acid solution
A sealed-end water manometer attached to an air duct reads 1598 cm. An open-end water manometer attached to the same duct reads 556.2 cm.
Explain why a buffer made of equal concentrations of CH3COOH and CH3COO- does not change in pH when a small amount of NaOH (a strong base) is added to the solution. Does the NaOH dissociate into ions when it is added to the solution?
Is 2-methyl-2-propanamine (C4H11N) a primary amine, secondary amine, tertiary amine, or quaternary ammonium salt? 2) Is N-methyl-2-propanamine a primary amine
