Methanol and ethanol are alcohol variants. Methanol contains only one carbon and ethanol contains two carbon in each molecule. Both substances can be used as energy sources, but methanol primarily serves as a research subject, and its use as a motor fuel has been mostly phased out in the United States.
Balanced chemical equation:
* moles of oxygen
4 Al + 3 O2 = 2 Al2O3
4 moles Al -------------- 3 moles O2
9.30 moles Al ---------- moles O2
moles O2 = 9.30 * 3 / 4
moles O2 = 27.9 / 4 => 6.975 moles of O2
Therefore:
Molar mass O2 = 31.9988 g/mol
n = m / mm
6.975 = m / 31.9988
m = 6.975 * 31.9988
m = 223.19 of O2
Hey there!
Density = 2.70 g/cm³
Volume = 10.0 cm³
Therefore:
Mass = density * volume
Mass = 2.70 * 10.0
Mass = 27.0 g
Answer:
Every sample of a given substance has identical intensive properties because every sample has the same composition
Answer:
