Find out the empirical formula of the following compound if a sample contains 0.104 mol K, 0.052 mol C, and 0.156 mol O;
What is the standard reduction potential and standard oxidation potential of water? I can't tell from the chart because water is in two places.
Explain why the absolute value of the work done by a process can never be greater than the absolute value of the Helmholtz free energy change.
a room contains 3.9 x 104 grams of argon. if air has a density of 1.7 gl and is 0.255 argon by mass what is the size of
A sample of gas occupies 1.55 L at 27.0°C and 1.00 atm pressure. What will the volume be if the pressure is increased to 50.0 atm, but the temperature is kept constant?
The volume of a certain bacterial cell is 1.60 µm3. What is the volume of 105 cells in liters (L)?
A hard time understanding redox reactions, how would I balance this equation αCr2O2-7(aq)+βH+(aq)+γCu(s)→δCr3+(aq)+?H2O(l)+κCu2+(aq) I don't get it because its not the same as a regular balance.
