Solve the ff.

1 ) A sample of He occupies 520 milliliters at 950 Torr and 25°C. If the sample is transferred to a one. 1-L flask at 25°C, what will be the gas pressure inside the flask? installment payments on your A balloon has temperature of 28°C. What will become the final temp of the gas if the amount is reduced to half the original beneath isobaric condition? 3. Calculate the volume occupied by 5. 23 kilogram of methane gas in STP. some. Dry ice is useful in maintaining frozen foods because it vaporizes to CARBON DIOXIDE (g) rather than melting to a liquid. How many l of LASER gas, assessed at STP, will be created by the vaporization of a prevent of dry ice that measures 12. 0 in x 12. 0 in x installment payments on your 0 in? The density of the dry out ice is definitely 1 . 56 g/cm3 five. Two flasks of equal volume will be connected by a narrow pipe (of negligible volume). The flasks and so are with nitrogen gas and, when both are immersed in boiling water, the gas pressure inside the system is 0. 55 atm. One of the flasks can then be immersed within an ice-water mix, keeping the different in boiling water. Calculate the brand new pressure in the system. Believe ideal gas behavior. six. Suppose that 12. 0 moles of H2S(g) is confined to 4. 860 L by 27°C. Compute the pressure exerted simply by H2S(g) from (a) perfect gas and (b) truck der Waals equations of state. Intended for H2S, a = 5. 484 L2 atm mol-2, b = 0. 0434 L mol-1. 7. Nitrogen forms a number of gaseous oxides. One of them has a density of just one. 27 g/L measured in 764 mm Hg and 150°C. Write the chemical formula of the mixture. 8. In 2 . 00 min, up to 29. 7 milliliters of This individual effuse through a small gap. Under the same conditions of temperature and pressure, 15. 0 milliliters of a mixture of CO and CO2 effuse through the gap in the same amount of time. Compute the percent composition by simply volume of the mixture. on the lookout for. Given that the critical heat and pressure of ethane are 32. 25°C and 48. twenty atm, respectively. Calculate the van der Waals constants a and b from the gas. 12. Nickel varieties a gaseous compound from the formula Ni(CO)x. What is the cost of x provided the fact within the...
