B water at 99c since it is the hottest
Answer:
Methylethanoate with the molecular formula; CH₃- CO₂-CH₃
Explanation:
The Molecular formula of the given compound CH₃ - CH₂- COOH is called propanoic acid. Molecular formula expresses the exact number and kinds of atoms of the elements present in the molecule of a compound. Propanoic acid is the second compound in the group of carboxylic acids. The certain similarities these carboxylic acids posses is due to the functional group - COOH. Functional groups is the categorization of atoms within molecules that possess their own certain characteristics which makes them distinct from other functional groups.
The molecular formula which represents an isomer of the given compound CH₃ - CH₂- COOH is called Methylethanoate with the molecular formula; CH₃- CO₂-CH₃
Isomers are existence of two or more compounds with the same exact molecular formula but with different molecular structures due to the difference in the arrangement of atoms or spatial orientation of atoms.
Loose material is compacted by pressure: the weight of the objects beginning to settle on top of it grows until it becomes immense that's how icebergs are formed too
Use this formula PV=nRT
Rearrange formula , question want V ,so
V=nRT/P
given
P= 3.00 atm
n=0.450 moles
R is ideal gas constant = 0.08206 L atm mol-¹K-¹
T in Kelvin so , (75 + 273)= 348 Kelvin (K)
Then insert all this information given with that rearranged formula V=nRT/P
- so, V= (0.45)(0.08206)(348) / 3.00
- = 4.284 L
Answer:
medium: The material or empty space through which signals, waves or forces pass. direction of propagation: The axis along which the wave travels. wave: A moving disturbance in the energy level of a field.
