The test for this is fairly simple.
We take a glowing match or splint near the gas sample, if the glow intensifies, oxygen is present.
If a lit splint or match goes out with a popping sound, this means that hydrogen is present.
Answer:
The minimum volume of the container is 0.0649 cubic meters, which is the same as 64.9 liters.
Explanation:
Assume that ethane behaves as an ideal gas under these conditions.
By the ideal gas law,
,
.
where
- is the pressure of the gas,
- is the volume of the gas,
- is the number of moles of particles in this gas,
- is the ideal gas constant, and
- is the absolute temperature of the gas (in degrees Kelvins.)
The numerical value of will be if , , and are in SI units. Convert these values to SI units:
- ;
- shall be in cubic meters, ;
- .
Apply the ideal gas law:
.
The answer would be 1,3,1,3
Answer:
C₃H₆O₃
Explanation:
Data:
EF = CH₂O
MM = 90. g/mol
Calculations:
EF Mass = (12.01 + 2.016 + 16.00) u = 30.03 u
The molecular formula is an integral multiple of the empirical formula.
MF = (EF)ₙ
MF = (CH₂O)₃ = C₃H₆O₃
