Calculate the volume of carbon dioxide at 20.0°C and 0.996 atm
produced from the complete combustion of 4.00 kg of methane.
Compare your result with the volume of CO2 produced from the
complete combustion of 4.00 kg of propane (C3H8).
Volume of CO2 from 4.00 kg methane: ___ L
volume of CO2 from 4.00 kg propane: ____ L
What volume of H2 gas will be produced at 1.0 atm and 28 degrees
Celsius if 10g of Na are mixed with 100g of H2O.The other product
of the reaction is NaOH
The decomposition of N2O to N2 and O2 is a first-order reaction.
At 730° C the half-life of the reaction is 3.58 × 103 min. If the
initial pressure of N2O is 5.50 atm at 730° C, calculate the total
gas pressure after one half-life. Assume that the volume remains
constant.
_____atm
What volume of O2 at 836 mmHg and 31 ∘C is required to
synthesize 12.5 mol of NO?
Additional info: The industrial production of nitric acid (HNO3)
is a multistep process. The first step is the oxidation of ammonia
(NH3) over a catalyst with excess oxygen (O2) to produce nitrogen
monoxide (NO)gas as shown by the unbalanced equation given
here:
?NH3(g)+?O2(g)→?NO(g)+?H2O(g)
A flask is filled with 3.0 atm of N2 and 4.0 atm of O2. The
gases react and NO2 is formed. What is the pressure in the flask
after the reaction occurs as completely as possible? Assume that
the volume and temperature in the flask remain constant.
(1) 4.0 atm (2) 5.0 atm (3) 6.0 atm (4) 8.0 atm (5) 10.0 atm
I keep getting 6atm but the answer is 5atm
Part A) A sample of a gas at 25°C and 1.0 atm
pressure has a volume of 2.5 L. The container is allowed to expand
until the pressure is 0.85 atm and the temperature is 15°C. The
final volume of the gas is __________ L.
Part B) A reaction is carried out that produces
hydrogen gas. The gas is collected in an inverted beaker over water
at 25 oC. The vapor pressure of water at 25
oC is 23.78 mmHg....
