They have free electron(s) on their outermost energy levels making them good conductors.
They have metallic bonds in their chemical structure.
They readily lose the electrons on their outermost energy levels, to bond with non-metals in ionic bonds to form chemical compounds called "salts"

People tend to speak more quietly in restaurants than they do when they are having an ordinary conversation Restaurant conversat
MArishka [77]

Answer:

A loud ordinary conversation following the supplied information in the question is about 4500 dB. But, in the official decibel system measure a loud conversation does not overcome 100 dB.

Explanation:

Using the supplied data of the exercise, we say that in a restaurant conversation the value is 45 dB. If we multiply this by 100 we will have a value for a laud ordinary conversation.

45×100 = 4500 dB.

but as I mentioned in the answer, in the official decibel system measure a loud conversation between 2 man reaches a maximal of 100 dB.

The following name is wrong. Draw the structure based on it and correct the name: 1,1,1−trimethylheptane
Nana76 [90]

2,2-Dimethyloctane is the correct name.

Eight C atoms make up the longest continuous carbon chain, hence the term "octane" for this molecule.

<h3>Description of the chemical structure</h3>
  • There are 31 bonds in the 2,2-Dimethyloctane molecule overall (s) There are 5 rotatable bonds and 9 non-H bonds (s).
  • Skeletal formula, which is the accepted notation for organic compounds, is another name for the 2D chemical structure illustration of 2,2-Dimethyloctane.
  • Skeletal formula, which is the accepted notation for organic compounds, is another name for the 2D chemical structure illustration of 2,2-Dimethyloctane.
  • In the 2,2-Dimethyloctane chemical structure, the carbon atoms are implied to be at the corner(s) and hydrogen atoms coupled to carbon atoms are not mentioned; instead, it is assumed that each carbon atom is connected to enough hydrogen atoms to form four bonds.
  • Based on the ball-and-stick model, which shows both the three-dimensional position of the atoms and the bonds tying them together, the 3D chemical structure image of 2,2-Dimethyloctane is created.
  • In order to provide a clearer picture of the atoms and bonds throughout the 2,2-Dimethyloctane chemical structure model, the radius of the spheres is thus smaller than the rod lengths.
<h3>Molecular Formula - C_{10} H_{22}</h3><h3>Chemical Properties</h3>
  • Calculated Log P: 6.434 
  • Molecular Weight: 142.2838
  • Bonds That Rotate: 9  
  • H  Acceptors : 
  • H Donors: 0
<h3>uses </h3>

2,2-Dimethyloctane, a gasoline hydrocarbon byproduct of aerobic biodegradation.

What is the overall equation for this chemical reaction?
Lady bird [3.3K]
We combine the two equations, like we would any mathematical system of equations. After addition of the two equations, we get:
Mg + 2H⁺(aq) + 2e⁻ → Mg⁺²(aq) + H₂(g) + 2e⁻
Cancelling like terms from both sides

Mg + 2H⁺(aq) → Mg⁺²(aq) + H₂(g)
