QUESTION 10 How do astrophysicists account for neutrino emission from the Sun? Solar flares create neutrinos with very energetic magnetic fields. Convection releases neutrinos, which random walk through the radiation zone. Fission in the Sun's core creates neutrinos when protons turn into neutrons. The annihilation of positrons and electrons in the core produces neutrinos. Fusion in the Sun's core creates neutrinos when protons turn into neutrons, QUESTION 11 How does the interstellar medium impact...

Can I have help with these questions based off the information provided? Information: The explosive picric acid is also known by the IUPAC name 2,4,6-Trinitrophenol. Picric acid is known as a primary explosive and the balanced equation for the explosion is 4 C6H3N3 O7 (aq) + 13 O2 (g) --> 6 H2O (g) + 6 N2 (g) + 24 CO2 (g) volume of gas produced by 1 g is 0.89 L Type bond broken # bond type Enthalpy (KJ/mol Total...

Exercise 5: I was changing 34 around too much that I just made it a separate exercise. Suppose 310. grams of ethanol (ethyl alcohol) is in an aluminum cup of 90.0 grams. Both of these are at 30.0C. A mass m of ice at - 8.5C is taken from a freezer and added to the alcohol in the cup. The final temperature of all the components is 18.0C. Assuming no heat was lost from the system, calculate the mass m...

Quantitative: In the 1950s liquid hydrogen was considered as a fuel for a new type of aircraft being developed, the SR-71 Blackbird (shown in Figure 1). Figure 1: The SR-71 Blackbird Early research on the project focused on which fuel to use for the Blackbird. Pratt & Whitney had a J-57 engine that was designed for kerosene and being considered for implementation on the Blackbird. The J-57 only took 5 months to convert to running on liquid hydrogen, however tests...

3) Using an order of magnitude method (Hill), estimate the TCI in year 2006 dollars for a grass-roots plant with 100,000-lb annual production using an order-of-magnitude method based on a 10,000-lb annual production. The plant contains three 1200-ft/min centrifugal fans, five 1500-ft/min centrifugal blowers, seven 100-ft' centrifugal separators, and two 100-ft shell-and-tube heat exchangers. You may assume all materials are carbon steel, the materials handled are primarily solid, and that this plant construction is done fully...
