Refer to the attached image. This does not depict the polymerization reaction of salicylic acid. It merely illustrates the structure of salicylic acid and what it looks like post-polymerization. The polymerization occurs through the linking of salicylic acid molecules, resulting in the formation of one water molecule.
Response:B) The octet of the carbon atom is incomplete within the molecule.
Explanation:
<span>Fluorine has an atomic number of 9, which indicates that each atom contains 9 protons and 9 electrons. One mole contains 6.0x10^23 entities, resulting in an answer of 4.</span>
Answer:
B) Iron (c=0.45 J/g°C)
Explanation:
It is given that the heat gained by water equals the heat lost by the metal
Thus,
With the negative sign indicating heat loss
Alternatively,
For water:
Mass = 120 g
Initial temperature = 21.8 °C
Final temperature = 24.5 °C
Specific heat of water = 4.184 J/g°C
For the metal:
Mass = 40.2 g
Initial temperature = 99.3 °C
Final temperature = 24.5 °C
Specific heat of metal =?
Hence,
This value aligns with iron. Therefore, the answer is B.
