The figure represents the initial contents of a reaction vessel mixture of nitrogen monoxide (NO) and oxygen (O2) at a pressure of 1 atm. Keeping the volume and temperature constant, what are the final total pressure (Ptot) and partial pressure of nitrogen dioxide (PNO2) when the reaction is complete (assuming a 100% yield)? 2NO(g) + O2(g) → 2NO2(g)  

A 1.0 g sample of zinc sulfide, ZnS, is mixed with 100.0 mL of pure water and 100.0 mL of a 0.100 M sodium sulfide, Na2S, solution. Which set of diagrams best represents the two solutions? The Ksp of ZnS is 3.0×10–23, and both solutions are saturated. Water molecules and sodium ions are omitted for clarity.

What is the correct formula for iron (III) sulfide?

The reaction of: NO(g) + Cl2(g) ⇌ NOCl(g) + Cl(g) Is found to have an equilibrium constant of 1.1×108 at a particular temperature. What does this mean?

Which aqueous solution all at 25 oC will have the highest osmotic pressure?

Rank the species from most to least soluble in water. Ba(NO3)2, Ksp = 4.64×10–3 Cd(OH)2, Ksp = 7.20×10–15 FeCO3, Ksp = 3.13×10–11

The formation of nitrogen trichloride is: N2(g) + 3Cl2(g) ⇌ 2NCl3(g)   ΔH = +232 kJ/mol Which change will decrease the concentration of the product?

What is the process to determine the mass (in grams) of carbon dioxide (CO2, molar mass = 44.01 g/mol) produced from 5.00 g of acetylene (C2H2, molar mass = 26.04 g/mol) and excess oxygen? 2C2H2(g) + 5O2(g) → 4CO2(g) + 2H2O(l)

What is the theoretical yield (in grams) of iron(III) carbonate that can be produced from 1.72 g of iron(III) nitrate and an excess of sodium carbonate?  The molar mass of iron(III) carbonate, Fe2(CO3)3, is 291.73 g/mol, and the molar mass of iron(III) nitrate, Fe(NO3)3, is 241.88 g/mol. 2Fe(NO3)3(aq) + 3Na2CO3(aq) → Fe2(CO3)3(s) + 6NaNO3(aq)
