A perfect gas has a constant volume heat capacity of C R V m = 1.5×R, . Calculate q and w for the process where 4.50 mol of this gas is heated with a 12 W heater for 400 seconds at a constant volume.
Consider the following balanced equation: 2 N2O5 → 4 NO2 + O2. If a 5.00 g sample of N2O5 undergoes this reaction, how many grams of O2 will also be formed?
Imagine a silica microsphere half of which is coated with a thin gold coating and having a trimethylammoniumpropanethiol molecule anchored to the gold.
Consider the reaction when aqueous solutions of sodium sulfide and manganese(II) sulfate are combined.
Based on the fact that the alloy has an HCP crystal structure, what general processing technique would you consider for the processing of the turbine blade? Explain your choice.
If 420 Joules are added to 20 grams of water to 30oC, what will be the final temperature of the water?
Hydrogen iodide decomposes according to the equation 2HI(g) H2(g) + I2(g), for which Kc = 0.0156 at 400ºC. 0.550 mol HI was injected into a 2.00 L reaction vessel at 400ºC. Calculate the concentration of HI at equilibrium.
