Answer:
the answer to this question is producer
Answer:
Explanation:
Use Dalton's law and the vapor pressure of water at 23.0 o C to correct the pressure to units of atmoshperes.
PT = Poxygen +Pwater
At 23.0 o C the vapor pressure of water is 21.1 mmHg. (This can be found on a vapor pressure table.)
762 mmHg = Poxygen + 21.1 mmHg
Poxygen = 762 mmHg - 21.1 mmHg
Poxygen =741 mmHg
Convert the corrected pressure to atmospheres.
(741 mmHg) (1 atm / 760 mmHg) = 0.975 atm
Use the ideal gas law to find out how many moles of gas were produced:
PV = nRT (remember to put volume in liters and temperature in Kelvin)
(0.975 atm) (.193 L) = n (.0821 L atm / mol K) (298 K)
n = (0.975 atm) (.193 L) / (.0821 L atm / mol K) (298 K)
n = 7.69 X 10-4 mol
Use the number of moles and the molecular weight of oxygen to find out how many grams of oxygen were collected.
(7.69 X 10-4 mol) (32.0 g / 1 mol) = 2.46 X 10-2 g
Answer:
provide steels-specific bins to families and provide people to collect the cans
Explanation:
The recycling process plays an important role in the saving of the environment. Recyling of steel cans uses less energy than manufacturing something from the scratch. In addition, the process creates jobs for the people. There are number of recycling usints that are making a living. In order to make the process faster and easier, the coucile can encourage each househild to have a can bin. This will be dedicated to the alumininium cans. This makes iyt easuetr to dispose the bins abs tha vcans. In addition, the council can employ more people who move from house to house collecting the cans.
