Metallic COpper is formed when aluminum reacts with copper(ii) sullfat. How many grams of metallic copper can be obtained when 54.0 G 0f Al react with 319 G of CuSO4?
What are the masses of CO and CO2 in the tank and what are the partial pressures of each of the three gases at 24C?
Sn2 requires a strong nucleophile while E2 requires a strong base. But relatively compared if you have a very strong base the E2 is preferred. Why is it so?
Calculate the mass of propylene glycol that must be added to 0.360 of water to reduce the vapor pressure by 2.88 torr at 40°C (Pressure of H2O is 55.3 torr at 40°C ).
petit discovered the empirical rule that the specific heat times the atomic weight of many solid elements is a constant: Using this rule, calculate the specific heat of copper and platinum.
If a gas is collected over water at 30.0oC in a 50.0 ml container and the pressure of the "wet" gas is found to be 645 torr, what would the pressure of the "dry" gas be in the same container and temp.
The solubility of the K3[Fe(C2O4)3].3H2O product at 00C is 4.7 g per 100 g water. Given this, calculate the maximum percent yield of product for your own reactant quantities.
Given the values of ΔH ° rxn , ΔS ° rxn , and T below, determine ΔS univ. ΔH ° rxn = 80kJ , ΔS rxn = 143J/K , T= 299K Express your answer using two significant figures.
A mixture of 40 Ml of methyl butyrate (MW-102.1 g/mol,d-0.89 g/mL) and 10 mL butyric acid (MW=88.1 g/mol, d=0.96 g/ML) is distilled.
One of the emission spectral lines for Be3+ has a wavelength of 253.4 nm for an electronic transmission that begins in the state with n = 5
Write equations for the reaction of each of the following with (1) Mg in ether followed by (2) additione of D2O to the resulting solution:
Calculate the mass percent of a solution that is prepared by adding 35.9 gram of NaOH to 30.2 g of H2O.
a 125 g metal block at a temperature of 93.2 Celsius degree was immersed in 100. g of water at 18.3 celsius degree. given the specific heat of the metal (Cp = 0.900 J/g Celsius), find the final temperature of the block and the water.
