Two nitro (NO,) groups are chemically bonded to a patch of surface. They can't move to another location on the surface, but they can rotate (see sketch at right). It turns out that the amount of rotational kinetic energy each NO, group can have is required to be a multiple of ɛ, where ɛ = 1.0 x 10 so forth – but it cannot have just any old amount of rotational kinetic energy. J. In other words, each NO, group could have ɛ of rotational kinetic energy, or 2ɛ, or 3ɛ, and Suppose the total rotational kinetic energy in this system is initially known to be 87ɛ. Then, some heat is removed from the system, and the total rotational kinetic energy falls to 66ɛ. Calculate the change in entropy. Round your answer to 3 significant digits, and be sure it has the correct unit symbol.

So you escaped the fate of wrapping hamburgers. The next step is to continue proving that you know dimensional analysis (it’s never too late for the hamburger people to come get you!) The great thing about dimensional analysis is that sometimes you can solve problems without equations. Here is such a case: a. All matter has a property called a specific heat capacity. For silver, this specific heat capacity is 0.24 J/°C · g. How much energy (in Joules) would be required to heat 120.0 g of silver (Ag) so that its temperature changes by 32°C? Use dimensional analysis, not an equation! Dimensional Analysis Practice Problems Page 6 of 6 b. Based on how you set up the problem above, what would be the equation? Fill in the rest of this expression to form your own equation (that you figured out by using dimensional analysis above.) You will use the terms “mass” “specific heat” and “temperature” and some mathematical operation signs). This answer is an equation, not…
Ammonia burns in air as follows:NH3(g) + O2(g) → N2(g) + H2O(g) (unbalanced)If x liters of N2(g) are formed by burning 9.8 L of ammonia and 9.8 L of oxygen with all species at the same temperature and pressure, what is the value of x?
Every day a certain amount of water evaporates from Earth’s oceans, lakes, and land surface and forms water vapor and clouds in the atmosphere. Every day a certain amount of rain falls back to Earth. Make the reasonable assumption that, on average, the energy absorbed by the evaporation and lifting of the water is equal to the energy released by its condensation and falling back to earth. The evaporation of one mole of water requires approximately 40.6×103 J of heat. An equal amount of heat is released when a mole of water condenses. The annual volume of rainfall on Earth is approximately 4.9×105 km3 and the average cloud altitude is 8.9 km above Earth’s surface. How much energy, in joules, is required every day to evaporate and lift the water?
Calculate how much energy would be needed for 64.8 g titanium at 19.4 oC to reach 582 degrees Celcius.
The synthesis of Hansa yellow dye takes place in a series of two steps. On Sunday June 9th, 1996 a violent runaway reaction occurred causing very significant damage to equipment and buildings. After a detailed analysis, the plant was rebuilt, and production resumed. What is the enthalpy of the overall reaction? Show work for credit. Can you explain which of the two steps was most likely to blame for the incident? Step 1: CsH;CIN2O2(aq) + NANO2(aq) + 2HCI(aq) → C6H3CIN3O2*(aq) + Cl(aq) + 2H2O(I) + NaCI(aq) AH1 = -1212 kJ/mol Step 2: C6H3CIN3O2*(aq) + Cl'(aq) + C10H10CINO2(aq) → C16H12C12N4O4(aq) + HCl(aq) AH2 = 637 kJ/mol %3| Overall Reaction: C6H5CIN2O2(aq) + NaNO2(aq) + HCI(aq) → 2H2O(1) + NaCI(aq) + C16H12CI2N4O4(aq) AHrxn = ? kJ/mol %3D
