Metals allow electric charge to move freely through them. Metals have a sea of delocalized electrons that are able to move freely throughout the metal structure.

Answer is: because of delocalized electrons in metallic bond.

Substances with metallic bond conduct an electric current in liquid and solid state, because they have mobile electrons.

Most metals have strong metallic bond, because strong electrostatic attractive force between valence electrons (metals usually have low ionization energy and lose electrons easy) and positively charged metal ions.

1. Metallic bond is a type of chemical bond.  

2. Metallic bond is formed between electrons and positively charged metal ions.  

3. Metallic radius is defined as one-half of the distance between the two adjacent metal ions.  

4. Metallic bond increace electrical and thermal conductivity.  

5. Metals conduct heat, because when free moving electrons gain energy (heat) they vibrate more quickly and can move around.

What is the iupac name of the following compound? <br><br> 2,2-dimethyl-4-ethylheptane
Lady bird [3.3K]

Answer:

The IUPAC name of the compound has already been given which is 2,2-dimethyl-4-ethylheptane.

Explanation:

The IUPAC (International Union of Pure and Applied Chemistry) is an authority in chemistry that provides a guideline and standardized methods in the naming of compounds formed from the periodic table.

In order the give an IUPAC name to a compound, certain steps needs to be followed, these includes:

--> Identify the functional group in the compound as this will form the suffix. For example if the functional group is an alkane the suffix will be -ane.

--> Identify the longest carbon chain (it may not be a straight chain) that contains the functional group. This forms the prefix. Example: if the longest carbon chain is 7 carbon atoms then the prefix will be hept-

--> All the carbons of the longest chain should be numbered

--> Identify branched groups on the chain and name them according to the number of carbon atoms. They usually end with -yl.

--> Finally, combine the elements of the name is a single word.

The structural formula of the IUPAC compound can be found in the attached file for a better understanding. The branched groups are circled.

In an acid-base titration, a base or acid is gradually added to the other until they have completely neutralized each other. Sin
Xelga [282]

Answer:

1/10 or 0.1

Explanation:

Quantities at which equivalence can be obtained are:

           

95, 96, 97, 98, 99, 100, 101, 102, 103, 104

Number of quantities = N = 10

Probability that the equivalency is obtained exactly at 100 mL can be calculated as follows:

P(X = 100) =  (Number of favourable outcomes) / (Total Number of Outcomes)

P(X = 100) = 1/10

P(X = 100) = 0.1

Which is a true statement about an exterior angle of a triangle?
wolverine [178]

The only true statement about an exterior angle of a triangle from the above is that it forms a linear pair with one of the interior angles of the triangle.

<h3>What is a triangle?</h3>

A triangle can be defined as a one of the plane shapes which has three sides and three angles

So therefore, the only true statement about an exterior angle of a triangle from the above is that it forms a linear pair with one of the interior angles of the triangle.
