Answer:
radical-initiated
Explanation:
Radical-initiated polymerization is unpredictable and difficult to control. The reaction proceeds indiscriminately and produces shortened chains, loops, and branches that create holes in the polymer. This reduces its mass to volume ratio.
Add up all the molar masses of the elements multiplied by the number of atoms each.
Molar mass of carbon = 12.01g
Molar mass of hydrogen = 1.01g
Molar mass of oxygen = 16g
9(12.01) + 8(1.01) + 4(16)
Molar mass of aspirin = 180.17g
Answer:
The answer to your question is: Includes sulfur and gain two electrons
Explanation:
Includes Chlorine This option is wrong, Chlorine belongs to group VII.
Includes Sulfur This option is true, Group VI includes Oxygen, Sulfur, Selenium, Tellurium.
Gain 2 electrons
. This option is true, Elements in group VI have six valence electrons so they gain to electrons to become estable.
Tend to form +2 ions This option is wrong, this elements form -2 ions
Have 5 valence electrons This option is wrong, this elements have 6 valence electrons.
Nitrogen is more reactive than oxygen and oxygen than chlorine
Answer:
Stretching vibration, and
Bending vibration (Rocking, wagging, Twisting and Scissoring)
Explanation:
- Stretching vibration: this causes change in the length of a bond
- Bending vibration: this causes change in the angle between two bonds
Bending vibration can occur as rocking, wagging, twisting and Scissoring vibration
2a) Rocking vibration: this causes change in angle between group of the atoms
2b) Wagging vibration: this causes change in angle between the plane of a group of atoms
2c) Twisting vibration: this causes change in the angle between the planes of two groups of atoms.
2d) Scissoring vibration: this causes the movement of two atoms toward and away from each other
