A 6.11g sample of Cu-Zn alloy reacts with HCL to produce hydrogen gas. If the hydrogen gas has a volume of 1.26L, temperature of 22 C and a pressure of 728 mm Hg, what is the percent of Zn in the alloy? (Copper does not react with HCL.)
How many joules of heat are lost by 3580 kg granite as it cools from 41.2°C to −12.9°C? The specific heat of granite is 0.803 J/(g•°C). Show your work.
the osmotic pressure of blood is 7.65atm at 37 degre celsius how much glucose should be used per liter for an intravinuous injection that is to have the same osmotic pressure as blood and R=.00821
Calculate the change in Gibbs Free energy of 1 mol N2 when its temperature is raised from 298 K to 348 K at 2 atm pressure. Given that the molar entropy of N2, measured in J/K.mol is given by S=A+BlnT, with A=25.1 and B=29.3 in SI unit.
