1. When solid mercury (II) nitrate is heated, it decomposes to form solid mercury (II) oxide, gaseous nitrogen dioxide, and oxygen
2. Copper metal reacts with hot concentrated sulfuric acid solution to form aqueous copper (II) sulfate, sulfur dioxide gas, and water
The solubility of nitrogen gas "N2" in water at 20oC and 520 mmHg is 5.0×10-4 mol/L. The Henry's law constant (in mol/L.atm) at 20oC for the solubility of nitrogen gas in water is: A) 7.3×10-4 B) 7.1×10-4 C) 6.9×10-4 D) 6.7×10-4 Show steps please.
Why must we the wavelength bet set to 447nm when the FeSCN2+ solution is an orange-brown colour
The best combination of reactants for preparing (CH3)2CHSH is a. (CH3)2CHBr + NaSH b. (CH3)2CHOH+CH3SH c. (CH3)2CHONa +CH2SH d. CH3CH2CH3 + NaSH
Calculate the molar Gibbs free energy change for the phosporylation of glucose by ATP to produce glucose-6-phosphate. Assuming the reaction happens at 310K and at pH 7. The concentration of ATP, ADP, G6P, and Glu are 1850 µM, 138 µM, 83 µM, and 50..
Na2SO3, to the calorimeter above that contains 20.00g of water at 23.15 degrees C, what will the final temp of the calorimeter be when the reaction gose to completion
The complete combustion of 1.076g of C9H8O in a bomb calorimeter ( Cccalorimeter=3.895 kJ/ degree C) produced an increase in temperature of 11.21C. Calculate the molar enthalpy of combustion in kJ/mol.
Kp = 3.7x10-6 at 900K for the synthesis of ammonia from N2 and H2. Assuming that ?Ho = -92 kJ, calculate Kp at 550 K
What is the pH for a buffer solution containing 0.49 molar acetic acid and 0.02 molar potassium acetate
Chemists often use molarity ,M in Moles/liter , to measure the concentration of solutions. Molarity is a common unit of concentration because the volume of a liquid is very easy to measure
write the name and the structural formula of the organic product that would result from the reaction below. dont forget
What is the pH of a one liter mixture of .15 M nitrous acid and .20 M sodium nitrite after .020 mol of HCl have been added (no change in volume). (Ka for nitrous acid is 4.0x10^-4.
