A133.7 ft3 volume of liquid hydrogen rocket fuel has a mass of 268 kg. calculate: the weight of the fuel at standard (earth) sea level conditions in n and ibr, the density of the fuel in kg/m3, and the specific volume in ft3/lbm (ibm=pound-mass, which is not the same as a a lbf or a slug)

The bubbles in a carbonated soft drink are produced when carbonic acid decomposes to form carbon dioxide and water. in a closed system, this equilibrium exists as why does a carbonated soft drink lose carbonation when the container is left open? a.water evaporates, which favors the formation of h2co3. b.pressure decreases, which favors the formation of h2co3. c.the open container warms up, which causes more gas to escape. d.co2is removed, which favors the formation of h2co3.
