How many total atoms in the compound Al3NO2

Chemistry

Tems11 [23]3 years ago
6 0

Answer:

6.02 \times  {10}^{23}   \: atoms

Explanation:

since every compound is equivalent to one mole of particles. This number is represented by avagadros constant which represents the atomic proportion from molar to physical mass on a human scale. This equates to the amount of particles per mole of substance(amount of substance).

6.02 \times {10}^{23}   \: {mol}^{ - 1}

this can be denoted in symbol form by

N_A

avagadros constant is defined as rational so the exact value is 6.02214076×10^23.

avagadros number : 1 mole

At the equivalence point of a titration of the [H+] concentration is equal to:
icang [17]

B. At the equivalence point of a titration of the [H+] concentration is equal to 7.

<h3>What is equivalence point of a titration?</h3>

The equivalence point of a titration is a point in titration at which the amount of titrant added is just enough to completely neutralize the analyte solution.

At the equivalence point in an acid-base titration, moles of base equals moles of acid and the solution only contains salt and water.

At the equivalence point, equal amounts of H+ and OH- ions combines as shown below;

H⁺ + OH⁻  → H₂O

The pH of resulting solution is 7.0 (neutral).

Thus, the pH at the equivalence point for this titration will always be 7.0.

Which of the following are strongly hydrogen bonded in the liquid phase? A) nitrilesB) esters C) secondary amides D) acid chlori
-Dominant- [34]

Answer: Option (C) is the correct answer.

Explanation:

Chemical formula of a secondary amide is R'-CONH-R, where R and R' can be same of different alkyl or aryl groups. Here, the hydrogen atom of amide is attached to more electronegative oxygen atom of the C=O group.

Therefore, the hydrogen atom will be more strongly held by the electronegative oxygen atom. As a result, there will be  strongly hydrogen bonded in the liquid phase of secondary amide.

Whereas chemical formula of nitriles is RCN, ester is RCOOR' and acid chlorides are RCOCl. As no hydrogen bonding occurs in any of these compounds because hydrogen atom is not being attached to an electronegative atom.

Thus, we can conclude that secondary amides are strongly hydrogen bonded in the liquid phase.
