Monomers combine via a dehydration reaction. A molecule of H20 or water is removed in this process.
Answer:
819 K
Explanation:
Given data
- Initial pressure (P₁): 1 atm (standard pressure)
- Initial volume (V₁): 250 mL
- Initial temperature (T₁): 273.15 K (standard temperature)
- Final pressure (P₂): 0.500 atm
- Final volume (V₂): 1500 mL
- Final temperature (T₂): ?
We can find the final temperature using the combined gas law.
The simplest whole-number ratio of atoms in a molecule or formula unit is called the empirical formula. The empirical formula is clearly different from the structural formula and the molecular formula. Not all substances that have the same empirical formula have the same molecular formula too.

Back down to earth
Hot air balloons don't have pre-planned landing spots due to the fact they travel where the wind takes them. Instead, our pilots will look for a suitable open space and bring their balloon to land in a safe and controlled manner, fully compliant with aviation law.
