Answer: D
Explanation:
Chlorine is in group 7 or (VII) in Roman numerals, which means it has 7 balance electrons. It only needs one electron to become stable, hence it is next to the noble gases
The electronic configuration of a chloride ion in a compound of BeCl2 is
2.8.8
This is because chlorine atom which electronic configuration 2.8.7 gain one electron form Be to form chloride ion with 2.8.8 electronic configuration. BeCl2 is an ionic bond which is formed by a metal and a non metal.metal (Be)loses electron and become positively charged while non metal (Cl2) gain electron and become negative charged.
Answer:
p-bromobenzyl cyanide
Explanation:
In a nucleophilic substitution, a nucleophile replaces a leaving group (halide ion) from a carbon atom, using a lone pair of electrons to form a new bond with the carbon atom.
In this reaction, the <u>cyanide ion is the nucleophile</u> and the <u>bromide ion is the leaving group.</u>
This nucleophilic substitution is an example of an SN₂ reaction. This reaction occurs in a single step, where <u>bonds break and form simultaneously.</u>
In this product, the nucleophile occupies the opposite stereochemical position to the original position of the leaving group. This result is known as an inversion of the carbon atom configuration.
To solve for the concentration of nitric acid in mol/L or also M. We use the equation,
M₁V₁ = M₂V₂
Where M stands for the molarity and V is for volume. Substituting the known values,
(0.10 M)(13.0 mL) = (M₂)(17 mL)
M₂ = 0.076 M
Thus, the concentration of the nitric acid is approximately 0.076 M.
