Compute the internal energy of two moles of argon gas assuming ideal behavior at 298 K. suggest two ways to increase its internal energy by 10J.
The value of ΔE for a certain change is 1325 J. During the change, the system releases 873 J of heat.How much work, expressed in joules, was involved?
A buffer contains 0.50 mol NH4^+ and 0.50 mol NH3 diluted with water to 1.0 L. How many moles of NaOH are required to increase the pH of the buffer to 10.00
A 20.2 g piece of solid Iron, Fe(s), is heated to 66.1 degrees Celsius and is dropped into a 50.0 g of water at 32.4 degrees Celsius. The specific heat of Fe(s) and water are 0.45 J/gC and 4.184 J/gC, respectively. What is the final temperature of..
You will take 10.0 mL of a 0.0100 M KIO3 solution, dissolve excess amounts of KI in it, and using the Na2S2O3 solution, titrate to the disappearance of the starch I2 color. Using the approximate molarity of the Na2S2O3 solution, calculate the appr..
The balance used to measure the mass of the metal reads low (for example, it reads 19.4 g instead of an actual 19.7 g). How will this error, due to miscalculation of the balance, affect the reported specific heat value for the metal. Explain.
Why Nusselt number can be treat as a ratio of conductive resistance to convective resistance
