In longitudinal waves, the oscillations are along the same direction as the direction of travel and energy transfer.
Sound waves and waves in a stretched spring are longitudinal waves. P waves (relatively fast moving longitudinal seismic waves that travel through liquids and solids) are also longitudinal waves.
Longitudinal waves show area of compression and rarefaction. In the animation, the areas of compression are where the parts of the spring are close together, while the areas of rarefaction are where they are far apart.
Jamal’s hair is behaving that way because he is in a cold area.
Answer:
0.087 g/cm^3
Explanation:
Density is Mass : Volume.
Volume = 12 x 8 x 9 = 864 cm^3
Mass = 75 g
Density = 75g/864 cm^3 = 0.087 g/cm^3
Answer:
The intermediates in this reaction are Cl and CCl₃.
Explanation:
- To indicate the intermediate in this reaction, we should firstly define the intermediate.
- The intermediate is the species that produced within the steps of the reaction and consumed in the later step/s and does not appear in the overall reaction (<em>neither reactants nor products</em>).
- The mechanism of the reaction contains 3 steps:
- Cl₂ ↔ 2Cl
- Cl + CHCl₃ → HCl + CCl₃
- Cl + CCl₃ → CCl₄
- The overall reaction is: Cl₂ + CHCl₃ → HCl + CCl₄
- So, the intermediates in this reaction are Cl and CCl₃.
- Thus, 2 moles of Cl is produced in the first step and consumed in the second and third steps.
- 1 mole of CCl₃ is produced in the second step and consumed in the third step.
