How many moles of gaseous boron trifluoride, BFstep three, are contained in a cuatro.34ten-L bulb at 788.0 K if the pressure is 1.dos20 atm? How many grams of BF3?
Iodine, I2, is a solid at room temperature but sublimes (converts from a solid into a gas) when warmed. What is the temperature in a 73.3-mL bulb that contains 0.292 g of I2 vapor at a pressure of 0.462 atm?
A leading altitude balloon is stuffed with step one.41 ten 4 L of hydrogen from the a temperature regarding 21 °C and you will a pressure of 745 torr. What is the number of the new balloon from the a top regarding 20 kilometres, in which the weather is –forty eight °C while the tension is actually 63.step 1 torr?
A cylinder of medical oxygen has a volume of 35.4 L, and contains O2 at a pressure of https://datingranking.net/cs/bbpeoplemeet-recenze/ 151 atm and a temperature of 25 °C. What volume of O2 does this correspond to at normal body conditions, that is, 1 atm and 37 °C?
A huge scuba tank ((Figure)) having a volume of 18 L are rated for a force from 220 pub. The latest container are filled during the 20 °C and it has sufficient air to offer 1860 L out-of sky in order to a scuba diver at the a pressure of dos.37 automatic teller machine (a depth out of forty-five feet). Try the fresh tank occupied so you can capability from the 20 °C?
A 20.0-L cylinder containing kg of butane, C4H10, was opened to the atmosphere. Calculate the mass of the gas remaining in the cylinder if it were opened and the gas escaped until the pressure in the cylinder was equal to the atmospheric pressure, 0.983 atm, and a temperature of 27 °C.
While resting, the average 70-kg human male consumes 14 L of pure O2 per hour at 25 °C and 100 kPa. How many moles of O2 are consumed by a 70 kg man while resting for 1.0 h?
A liter of methane gas, CH4, at STP contains more atoms of hydrogen than does a liter of pure hydrogen gas, H2, at STP. Using Avogadro’s law as a starting point, explain why.
The effect of chlorofluorocarbons (such as CCl2F2) on the depletion of the ozone layer is well known. The use of substitutes, such as CH3CH2F(g), for the chlorofluorocarbons, has largely corrected the problem. Calculate the volume occupied by 10.0 g of each of these compounds at STP:
As the 1 g of radioactive element radium decays over 1 12 months, it produces step 1.sixteen ten 18 alpha dust (helium nuclei). For each leader particle will get an enthusiastic atom from helium gas. What is the stress inside pascal of your helium gas delivered when it takes up a number of 125 mL at the a fever off 25 °C?
A good balloon that have an amount of L within 21 °C and you can 0.981 automatic teller machine arrives and only hardly clears the top Install Crumpet inside the United kingdom Columbia. If your final volume of the fresh new balloon are L from the a beneficial temperature of 5.twenty four °C, what is the pressure educated of the balloon since it clears Install Crumpet?
When your heat out of a predetermined number of a gas was doubled on ongoing volume, what takes place towards the pressure?
In the event the amount of a fixed quantity of a gasoline is tripled at the ongoing temperature, what the results are into stress?

Solution (a) The fresh new normally consists of an amount of isobutane gasoline from the a reliable frequency, therefore if the heat are improved from the temperatures, pressure will increase proportionately. High temperature could lead to high pressure, evoking the can be to-burst. (Also, isobutane try combustible, therefore incineration trigger the new can also be to explode.)
