Write the structure of the product obtained when cyclohexane is used to decolorize bromine-containing solutions
The resulting W3 was transferred to 500.0 mL of 1.00 M HCl. A 100.00 mL aliquot of the HCl solution required 10.13 mL of 0.08840 M potassium permanganate (KMnO4) to reach the purple endpoint
list three acid, bases, and salt commonly used in therapeutic processes.
A mysterious material was purified from safflower oil (hint: full of fatty acids). Upon ozonolysis it gave the following compounds in their respective molar ratios.
How many molecules of ethanol C2H5OH are present in 135 g of ethanol? The density of ethanol is 0.789 g/cm3?
sulfur dioxide was allowed to effuse through a small opening under constant pressure conditions. It required 179 s for 1.00 L of this gas to effuse. Calculate the effusion time of arsine (AsH3) under identical experimental conditions
If you make three serial 1:5 dilutions, using the solution above, what is the concentration of the final solution?
A 1- L flask is filled with 1.40 g of argon at 25?. A sample of ethane vapor is added to the same flask until the total pressure is 1.05 atm.
Calculate the Q for the water in Joules (c for water is 4.184J/g degrees celsius). Determine the Q for the metal in Joules based on your knowledge of conservation of energy. (you cannot use the Q=mcdeltaT equation, because you do not know the c fo..
The concentration of methane in the biogas leaving an anaerobic digester (part of a wastewater treatment system) is 55% (volume basis) at 50 °C. The remaining 45% is CO2.
For a given sample of {rm CH_3OH}, the enthalpy change on reaction is 19.0 kJ. How many grams of hydrogen gas are produced?
How much heat (in kJ) is required to warm 16.0g of ice, initially at -11.0 C, to steam at 112.0 C? The heat capacity of ice is 2.09 J/g*C and that of steam is 2.01 J/g*C.
