What is the area on the earth's surface directly above where an earthquake originates?

Answer:

Chlorine

Explanation:

The Polarity of an atom is characterized as the dipole to dipole intermolecular forces between the slightly positively-charged end of one molecule to the negative end of another or the same molecule. Thus, the 'chlorine' atom would help in enhancing the polarity of hydrogen bromide(HBr) with 3.16 electronegativity as we know, the electronegativity increases if we move upwards in the periodic table.

Answer:

Sudden motions in Earths mantle causeing the crust to shift.

Explanation:

We can verify the properties as follows;

1) Sour taste - Put some soda on your tongue

2) Corrode metals - Put a little soda on a clean metal surface

3) Effect on Litmus paper - Dip a blue litmus paper in soda

4) Electrolysis - Add two electrodes to soda and connect a battery.

Soda, specifically carbonated beverages like cola or soda pop, typically exhibits acidic properties. The acidity of soda is primarily due to the presence of carbonic acid (H₂CO₃), which forms when carbon dioxide gas (CO₂) dissolves in water.

When carbon dioxide is dissolved in water under high pressure, it forms carbonic acid through the following reaction:

CO₂ + H₂O ⇌ H₂CO₃

Option D is the correct alternative.

We have a chemically unreactive element.

We have to determine which term best describes this atom.

Reactivity in chemistry is the impulse for which a chemical substance undergoes a chemical reaction, either by itself or with other materials.

According to the question -

An atom that that does not react with the other atoms belongs to those elements which are chemically unreactive or inert elements. The reason behind their inertness is their completely filled outermost shell which can accommodate a maximum of 8 electrons which is as shown by their electronic configuration -  1s²2s²2p⁶. Hence, they are highly stable and don't react with other elements. Ex - Helium, Argon, Neon etc.

Hence, Option D is the correct alternative.

i got it right on edg 2020 and they use ether in pokemon games to heal PP so that makes logical sense lol

The class of organic compounds that are used in anesthetics is:

A. Ether

It is a functional group consisting of C and O.

Anesthetics are an assorted gathering of medications with especially unique synthetic designs, going from basic inorganic atoms like nitrous oxide to additional perplexing natural specialists.

Organic compound is one that contains a bond with a carbon particle. In ethers, the practical gathering that is available is C=O. Ether, as a fluid, discharges fumes that are breathed in. Another very powerful fluid sedative is propofol, controlled intravenously.

Thus, correct option is A.

The study of fossil mammals comes under vertebrate paleontology

(aka vertebrate paleontology)

Answer:

The study of fossil mammals comes under vertebrate paleontology.

Explanation:

Paleontology is the study of fossils which tries to explain the evolution of organisms, their environment and interactions with each other. The various sub divisions of paleontology are vertebrate paleontology, invertebrate paleontology , micropaleontology, paleobotany, palynology etc.

The study of vertebrate fossils, from primitive fishes to the immediate ancestors of modern mammals is known as vertebrate paleontology. Invertebrate paleontology deals with the study of invertebrate animal fossils, such as molluscs, echinoderms, arthropods and annelid worms. Paleobotany studies fossil plants which includes the study of fossil algae and fungi in addition to land plants.  Micropaleontology is the study of microscopic fossil organisms, regardless of the group to which they belong.

Explanation:

Answer:

The nucleus of the atom contains two subatomic particles, the protons which are positively (+) charged and the neutrons which are neutral (no charge).

Explanation:

Answer: Comparing rock layers in distant places can be a challenge for geologists since these layers may have different environmental factors that caused different transformations in them.

Therefore, when it is necessary to establish a comparison between layers of rocks in different ligands, geologists must establish steps to make an efficient comparison and have results consistent with reality. To do this, they must first compare a layer in one location with layers in other locations, assign relative age to a layer in one location, and identify index fossils in one or more layers in one location.

Answer:

9.9 moles

Explanation:

What we know:

P = 2.3 atm   V = 120 L  

R= .0821 L atm/K mol   T= 340 K

What we're looking for: n = ?

2.3 atm ( 120 L) = n (.0821 L atm/K mol) (340 K)

        2.3 ( 120 ) = n (.0821 / mol) (340)    

                  276 = n (27.914 / mol )

                   9.9 = n / mol

            9.9 mol = n

True, Plants don't have brains, but they still adapt to their environments.

Adaptation is a process where they are changing their nature to suit the environment.

We have seen that plants do adaptation according to the environment, as in the summer season their leaves are hanging down but in the rainy season they show blossoms and green leaves. So, according to the environment for the survival and reproduction they adapt their body.

Hence, plants have no brains, but they still adapt.

Answer:

765 g Co(NH₃)₆Cl₃

General Formulas and Concepts:

Explanation:

Step 1: Define

2.86 mol Co(NH₃)₆Cl₃

Step 2: Define conversions

Molar Mass of Co - 58.93 g/mol

Molar Mass of N - 14.01 g/mol

Molar Mass of H - 1.01 g/mol

Molar Mass of Cl - 35.45 g/mol

Molar Mass of Co(NH₃)₆Cl₃ - 58.93 + 6(14.01) + 18(1.01) + 3(35.45) = 267.52 g/mol

Step 3: Dimensional Analysis

[tex]2.86 \ mol \ Co(NH_3)_6Cl_3(\frac{267.52 \ g \ Co(NH_3)_6Cl_3}{1 \ mol \ Co(NH_3)_6Cl_3} )[/tex] = 765.107 g Co(NH₃)₆Cl₃

Step 4: Simplify
