Most rare diseases are genetic, and thus are present throughout the person's entire life, even if symptoms do not immediately appear. Many rare diseases appear early in life, and about 30 percent of children with rare diseases will die before reaching their fifth birthday. With a single diagnosed patient only, ribose-5-phosphate isomerase deficiency is considered the rarest genetic disease.
When the temperature in the core reaches about 100 million degrees, the helium will begin to fuse into carbon by a reaction known as the triple-alpha process, because it converts three helium nuclei into one carbon atom.This generates a great deal of heat.n heavier stars, the oxygen can in turn fuse with the helium to make neon.) Helium fusion produces only 9% as much energy per kilogram as hydrogen fusion, so energy-wise, the Sun continues to be mainly a hydrogen reactor. 90% of its luminosity still comes from burning hydrogen.
Calculate the number of kilograms of helium needed to inflate a balloon to a volume of 100,000 L at an atmospheric pressure of 250 mmHg and a temperature of -35 Â°C. A. 1.68 kg B. 3.36 kg C. 5.21 kg D. 6.74 kg E. 5120 kg 23. Calculate the density, in g/L, of CO 2 gas at 27Â°C and 0.50 atm pressure.2. Calculate the molar mass of a gaseous substance if 0.125 g of the gas occupies 93.3 mL at STP. 83. What is the density, in molecules per cubic centimeter, of N 2 gas at 25Â°C and 650 mmHg? 84. An aerosol can with a volume of 0.50 L has a bursting point of 2.6 atm.
