Answer:

Explanation:

In one mole of liquid HF , no of molecules is 6.02 x 10²³.

Each molecule forms two hydrogen bonds on an average so no of hydrogen bonds per mol ih HF is

2 x  6.02 x 10²³.

= 12.04 x 10²³ .

In water no of hydrogen bonds per molecule of water is 4 . So in one mole of water no of hydrogen bonds is

4 x 6.02 x 10²³.

= 24.08 x 10²³ .

Write the following isotope in nuclide notation (e.g., “ 14/6C”): copper-70
Mars2501 [29]

       ⁷⁰₂₉Cu

Explanation:

Copper-70 isotope in nuclide form.

  A nuclide is designated as:                    ₙᵇX

       Where X is the symbol of the atom

      b is the mass number of the atom

     n is the atomic number

Mass number is the number of protons and neutrons in an atom. These particles makes up the bulk of the mass of an atom.

Atomic number is the number of protons in an atom. For neutral atom, it is the same as the number of electrons.

    To write Copper-70 in nuclide format:

         Symbol of Copper is Cu

         Mass number is 70

       Atomic number from periodic table is 29

                             ⁷⁰₂₉Cu

Can anyone answer this question?
-Dominant- [34]
Hello! Those are called the isotopes of those elements!! They have more than just one form and each has it’s own AMU’s so the multiple numbers above different elements, represent the isotopes of those elements. Carbon is a good one just for one example.

Hope this helps you out! Questions please just ask! Thanks!

Answer:

D equal numbers of protons and electrons​

Explanation:

An atom of an element will always contain equal number of protons and electrons.

Atoms are electrically neutral because the number of positive charges and negative charges within them are always equal.

  • An atom is the smallest indivisible particles of an element that takes part in a chemical reaction.
  • The positively charged particles within an atom are the protons.
  • The negatively charged particles within an atom are the electrons.

For;

 So number of protons = number of electrons within an atom.

A correct name for the following compound is:_________.a) 4-bromo-3,8-dimethylbicyclo[5.2.2]nonane b) 3,8-dimethyl-4-bromo-bicyc
mixer [17]

Answer:

e) 4-bromo-3,8-dimethylbicyclo[5.2.0]nonane

Explanation:

The missing image of the the  compound we are to name is attached below.

Before we can name an organic compound; It is crucial we know the guiding rules in naming them.

1. Select the longest continuous carbon chain as the root hydrocarbon and name according to the number of carbon atoms it contains, adding appropriate suffix to indicate the principal substituent group.

2. Number the carbon atoms in the root hydrocarbon from the end which gives the lowest number to the substituents.

3. If the same substituent is present two  or more times  in a molecule; the number of this substituent is indicated by the prefix di -(2), tri - (3) , tetra - (4) etc attached to the substituent name.

4. If there is more than one type of substituent in the molecule ; the substituents are named according to the alphabetical order but where  there are mixed substituents ; the inorganic are named first.

5. In selecting and numbering the longest continuous chain, the functional groups are given preference over substituents., i.e the functional group is given the smallest possible number.

In the light of the above guiding rules; we were able to name the given compound because the compound contains nine carbons in the ring form which result to root name nonane. The two methyl are on the third and eight carbon; bromine is on the fourth carbon ; there are two cyclic ring present in the compound where we have 5 carbons in one structure, another 2 carbons in the second structure and zero carbon in the bridge structure which eventually result to the correct  name:

4-bromo-3,8-dimethylbicyclo[5.2.0]nonane
