Describe how the properties of the compound carbon monoxide (CO) differ from the properties of the
ElenaW [278]

Explanation:

There is a clear cut difference between a compound and an element:

  • A compound is made up of substances composed of two or more kinds of atoms or elements joined together in a definite grouping.
  • An element is a distinct substance that cannot be split-up into simpler substances. These substances are only made up of one kind of atom.

Compounds are formed so that unstable elements can attain stability.

Carbon monoxide is made up two elements: Carbon and oxygen that have combined chemically together.

  • Carbon monoxide is a toxic gas and it is different from oxygen atom and carbon atom.
  • Carbon is a solid but carbon monoxide is a gas.
  • Oxygen atom does not exists on its own but it exists as Oxygen gas O₂
  • The properties of carbon monoxide clearly differ from that of oxygen and carbon.

A volume of 5.0 L of gas at a temperature of 25°C is cooled to a temperature of -120°C at constant pressure. What is the new vol
lorasvet [3.4K]
V1 = 5L = 5000ml V2 = ?
T1 = 25°C = 25+273 T2 = -120°C
= 297K = -120+273
= 153K
By Charles Law,
V1/T1 = V2/T2
5000/297 = V2/153
By solving,
V2 = 2.576L

A 55.0 gallon drum weighs 75.0 lb when empty. What will be the total mass when filled with ethyl alcohol? ( Density = 0.789 g/mL
daser333 [38]

Answer:

mass drum (filled) = 198.083 Kg ( 436.306 Lb )

Explanation:

⇒ mass drum = 75.0 Lb * ( 454 g / Lb) = 34050 g ( 34.05 Kg )

⇒ volume drum = 55.0 gal * ( 3.78 L/gal ) = 207.9 L

⇒ density CH3CH2OH = 0.789 Kg/L

⇒ mass drum (filled) = 34.050 Kg + ( 207.9 L * 0.789 Kg/L )

⇒ mass drum (filled) = 34.050 Kg + 164.03 Kg

⇒ mass drum (filled) = 198.0831 Kg
