During the time of Thompson and Dalton, no one studied their theories because the technology at the time didn't allow for further study in conducting their works. People were focused on other things. But it was revived and revised because of Neils Bohr and his atomic structure that led to more theories and eventually studies that continued on the works of Thompson and Dalton.
Answer:
The more optically dense that a material is, the slower that a wave will move through the material. ... So as the index of refraction value increases, the optical density increases, and the speed of light in that material decreases.
S + O → SO -71kcal
Explanation:
The reaction describe is a thermochemical equation. In the reaction above, since heat is liberated, this is an exothermic reaction.
- In an exothermic change heat is liberated to the surroundings.
- At the end of the reaction, the surrounding becomes hotter.
- The value of the heat change is assigned a negative sign.
1 mol of liquid sulfur (S (l)) = S
1 mol of gaseous oxygen (O2 (g)) = O
gaseous sulfur dioxide (SO2) = SO
releasing 71kcal = -71kcal
S + O → SO -71kcal
