When 0.538 g of Neon is added to an 800 cm^3 bulb containing a sample of argon, the total pressure of the gases is found to be 1.17 atm at a temperature of 295 K. Find the mass of the argon in the bulb.
The energy change, ?H, associated with the following reaction is +81 kJ. NBr3(g) + 3 H2O(g) → 3 HOBr(g) + NH3(g) What is the expected energy change
Pentane (C5H12) burns in oxygen to produce carbon dioxide and water via the following reaction:
Problem- Determine the percent ionzation of a mixture of 0.5 M solution of CH3NH3Cl and 0.4 M CH3NH2 at 25 degrees C.
Note that in some cases, the "product" may be the result of a proton transfer reaction. Do not assume that an aqueous workup (H3O+) is performed unless it is specified
A 1.6 g sample of a molecular compound is dissolved in 104 g of tetrachloromethane (carbon tetrachloride). The normal boiling point of the solution is 61.51degreesC, the normal boiling point of CCl4 is 61.2degreesC. The boiling point constant for ..
