50 " mL of " a mixture of NH3 and H2 was completely decomposed into N2 and H2 by sparking. 40 " mL of " O2 was then added and the mixture was sparked again. After cooling the mixture was shaken with alkaline pyrogallol and a contraction of 6 mL was observed. Calculate the percentage...
A mixture containing 4.562×10-3mol H2(g),7.384×10-4mol I2(g),and 1.355×10-2mol HI(g) in a 1.0 L container at 425.4℃ is at equilibrium. If 1.000×10-3 mol I2(g) is added, what will be the concentration of H2(g), I2(g) and HI(g) after the system has again reac...
A mixture of 4.00 grams of CH4, 1.00 grams of H2, and 5.50 grams of CO2 is brought to 27 degrees Celsius and 749 torr. What is the partial pressure of CH4 in the mixture? A gas mixture contains each of the followin...

The reaction zone of flame 2 became wider due to the injection of H2 in the outer ring of the burner. Hence, a fraction of the hydrogen reacted with the oxygen of the surrounding air containing 80% nitrogen, which led to an approximately 200 K smaller temperature at the outer edge of ...
A mixture of 4,4′,4″-tricarboxyltriphenylamine (H3tca) (18.9 mg, 0.05 mmol), (E)-1,2-di(pyridin-4- yl)diazene (9.2 mg, 0.05 mmol), and Zn(NO3)2·6H2O (29.8 mg, 0.1 mmol) was dissolved in ethanol/water (9/1, 5 mL) in a screw capped vial. The...
