The structures shown are examples of Constitutional Isomer.
In Chemistry, an isomer refers to a molecule that is similar to another but has differences. These differences can be:
- A difference in the constitution: The molecules have the same formula but the connectivities between elements or arrangement is different.
- Arrangement in space: The molecules have the same formula and connectivity, but they look different to do an arrangement in space of a position.
The molecules shown have the same formula because the elements in each pair are the same. However, the way these elements are connected is slightly different because the Br and the CH3 are connected to different carbons.
Based on this, the difference is the connectivity or constitution, and therefore these are constitutional isomers.

The answer is rings, I know this because i took a test about it and I got it right
D. Not all mixtures are heterogeneous
Answer:
129,66 g
Explanation:
Desde,
Número de moles = concentración * volumen
concentración = 2 M
volumen = 875 ml
Número de lunares = 2 * 875/1000
Número de lunares = 1,75 moles
Número de moles = masa / masa molar
masa molar de hidróxido de calcio = 74.093 g / mol
1,75 moles = masa / 74,093 g / mol
masa = 1,75 moles * 74,093 g / mol
masa = 129,66 g
