Answer: True.
Explanation.
The group 7A is actually named group 17.
That group is the halogens: F, Cl, Br, I, At, and Ts (Ts is one of the last elements discovered).
Those elements have 7 valence electrons (notice that it is the same number as the second digit in 17).
The atoms with 7 valence electrons will "easily" gain one electron to get the configuration of the next noble gas (8 valence electrons). That is why these elements gain electrons to form ions.
When atoms gain electrons form anions (negative ions). For example: F(-), Cl(-), Br(-), I(-).

Answer:
electrophilic addition
Explanation:
CH3 - CH = CH2 + Cl-Cl ---> CH3 -CH(Cl) - CH2(Cl)
Explanation:
Dimethylamine
Dimethylamine is a colorless liquid or gas with a fishy or Ammonia-like odor. It is used as a solvent and in making rubber, textiles, drugs, and other chemicals.
Converting between atmospheres and millimeters of mercury. One atm. equals 760.0 mm Hg, so there will be a multiplication or division based on the direction of the change. Solution: multiply the atm value by 760.0 mmHg / atm.
