7 0
The moles of ammonium nitrate needed to dissolve 0.35 moles
The moles of water that will react is 0.35 moles as due to ratio
so mass of water will be 0.35 x 18=6.3g 
                                 MASS OF WATER WILL BE 6.3 g

What is the net charge of the ionic compound calcium fluoride
yKpoI14uk [10]

Answer:

  • <em>The net charge of the ionic compound calcium fluoride is </em><u><em>zero (0).</em></u>

<em>Explanation:</em>

<em>Ionic compounds,</em> such as covalent ones, have zero net charge; this is, they are neutral.

Substances with net positive charge are cations and substances with net negative charge are anions.

The charges in the <em>ionic compound calcium flouride</em> are distributed in this way:

  • Compound formula: CaF₂

  • Calcium charge: Ca²⁺: this is, each calcium ion has a 2 positive charge

  • Fluoride charge: F⁻: each fluoride ion has a 1 negative charge.

  • Then, the <em>net charge</em> is: 1 × (2+) + 2 × (1-) = +2 - 2 = 0.

So, a two positve charge, from one calcium ion, is equal to two negative charges, from two fluoride tions, yielding a <u>zero net charge</u>.

Robert has pure samples of both D-ribose and D-arabinose, but he forgot to label them. He only has some nitric acid, the reagent
Sauron [17]

Answer:

Following are the responses to the given question:

Explanation:

Since HN03 is an oxidation substance D-ribose u.ith oxidized to form in rubric acid Ribose is chiral, but rubric acid is achiral because of its symmetry mirror level, Hence no infrared roster in the sample holder is observed.

Please find the attached file.

D-Arabinose, on either hand, gives optical aldaric acid with such a net optical rotation observed inside the polarimeter for diagnosis with HN03.

During electrophilic aromatic substitution, a resonance-stabilized cation intermediate is formed. Groups, already present on the
DIA [1.3K]

Answer:

See explanation and image attached

Explanation:

Aromatic compounds undergo electrophilic aromatic substitution reactions in which the aromatic ring is maintained.

Substituted benzenes may be more or less reactive towards electrophilic aromatic substitution than benzene depending on the nature of the substituent present in the ring.

Substituents that activate the ring towards electrophilic substitution such as -OCH3 are ortho-para directing.

The major products of the bromination of anisole are p-bromoanisole and o-bromoanisole. The resonance structures leading to these products are shown in the image attached.
