Which of the following best describes a Lewis base?

Chemistry
2 answers:
Semenov [28]3 years ago
7 0

Answer: Option (C) is the correct answer.

Explanation:

According to Lewis, a base is a substance or specie which is able to donate electrons.

For example, NH_{3} is a lewis base because nitrogen has a lone pair of electron.

Therefore, when ammonia is dissolved in HCl it will accept the hydrogen atom as nitrogen gave electron to the hydrogen atom. As a result, hydrogen bonds with nitrogen atom.

             NH_{3} + HCl \rightarrow NH^{+}_{4}Cl^{-}  

Thus, we can conclude that it donates electrons in solution best describes a Lewis base.

A geologist finds an area with a lot of slate, a type of metamorphic rock, on the surface of the land. What might this indicate
Elan Coil [88]

Answer:

Explanation:

Two things that can be deduced by this finding would be that the location was most likely a very muddy area with lots of clay minerals, as well as having lots of crustal movements. This is because slate is created when crustal movement buries clay minerals and other materials in the crust of the Earth. This is later melted and squeezed together from the sheer heat that is applied  being so far underground. Therefore, creating what we now know as Slate.

A neutral atom has 8 electrons and 8 neutrons. Which of the following correctly represents the atom? A) carbon-16 B) oxygen-16 C
bija089 [108]

Answer:

D

Explanation:

Oxygen is the 8th element in the periodic table. This means that oxygen has 8 protons and 8 electrons. In order to get the number of neutrons you take the atomic weight in this case 15.9999~16 and you subtract it by the number of protons (16-8).

Answer:

Boron

Explanation:

An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.

All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 6 protons than it must have 6 electrons. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.

For example

In given atomic model we can see that there are five electrons out side the nucleus it means this atomic model is of that element which have atomic number 5 and it is boron.

It has 5 electron 5 proton and 6 neutrons.

It means its atomic number is five and mass number is 5+6 = 11

Use the IUPAC nomenclature rules to give the name for Mg(ClO4)2
Makovka662 [10]

Answer:

The answer to your question is Magnesium Perchlorate

Explanation:

IUPAC Rules to name ternary salts of chlorine

1.- Ternary salts use prefixes and suffixes it depends on the number of oxygens they have.

Example

Metal + Chlorine + 1 oxygen =  Name of the metal + hipo chlor + ite

Metal + Chlorine + 2 oxygens = Name of the metal + chlor + ite

Metal + Chlorine + 3 oxygens = Name of the metal + chlor + ate

Metal + Chlorine + 4 oxygens = Name of the metal + per + chlor + ate

For this compound the name is  Magnesium Perchlorate.
