There are some methods that differentiate waves; one thing is by its medium.
Electromagnetic waves did not require a medium for transmission such as in a
vacuum while mechanical waves require a medium to travel such as air, water or
anything that can serve as a transmission aid.
The most common sample of EM waves in
telecommunication is radio,
light and infra-red signals. An example of a mechanical wave is a sound
wave, which requires air to travel. Oscillating molecules made the
sound waves.
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.
Answer:
B
Explanation:
because a periodic table shows the arrangement of element according to their atomic number and their valence neither
isotopes nor colour
Answer:
1. Covalent bonds can form between two nonmetal atoms.
2. Covalent bonds can form between atoms of the same element.
3. Covalent bonds can form between atoms of different elements.
