3.45 g of an unknown gas at 41 °C and 1.00 atm is stored in a 1.25-L flask. What is the density of the gas ? What is the molar mass of the gas.
The cell potential of the following electrochemical cell depends on the gold concentration in the cathode half-cell: Pt(s) | H2(g,1atm) | H+(aq,1.0M) | Au3+(aq,?M)|Au(s).
A traveling wave is produced on a rope. The wave travels until it hits a wall and it is reflected. If the speed of the wave is 1.8 m/s and it takes 6.5 s to get back to the starting point, how long (m) is the rope. Round to two decimal places, do ..
Equilibrium constant (Kc) is 1 and inital concentrations of A and B are Cao and zero (Cbo = 0), respectively. Da is equal 2 for each reactor in series configuration. What is the overall conversion of A for above equilibrium reaction?
