Answer:

Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges. While the process of forming these mountain ranges is volcanic, volcanoes and earthquakes along oceanic spreading ridges are not as violent as they are at convergent plate boundaries.

Answer:

C-Fault block mountain

Explanation:

Tension occurs at divergent boundaries. Tesnion is a type of stress that occurs when plates move apart. Rocks stretch apart creating fault block mountains

Which of the following would not be considered renewable forms of energy?

sertanlavr [38]

Answer : The correct answer is A. Nuclear reactors using Pu-239

B. burning coal

The sources which are not renewable are known as "non- renewable sources of energy .

Non - renewable sources are those which get expired after rapid use and can never be reproduced . These sources replenishes in very long time . Examples : Coal , petrol or fuels etc .

1) Nuclear reactors using Pu-239 : Nuclear reactors uses radioactive elements like uranium , plutonium etc , which are present in limit . after frequent use of these elements , they will vanish off , Hence we can say nuclear reactors are Non renewable source of energy .

2) Burning coal : Coal is used as one of the major source of fuel . On rapid utilization of coal they will finished from earth . It takes thousand of year for formation of coal . Hence , it is a Non -renewable source .

3) Photo-voltaic cell: These are cells which used solar energy . Solar energy is obtained from sun . Hence solar energy is renewable source of energy so is the photo voltaic cell .

4) Geothermal energy : Geothermal energy is source of energy that is extracted from earth's thermal energy . Since thermal energy of earth is present in very large amount and can be reproduced , hence it renewable source of energy .

5)Wind energy : Wind energy is source of energy that is obtained from wind. And wind is renewable source so the wine energy too .

Consequently , we can say only two of them " Nuclear reactors and burning of coal " are Non renewable force of energy .

In terms of electrons, what happens when Cations bond with anions?

Black_prince [1.1K]

Answer:

when an atom, typically a metal, loses an electron or electrons, and becomes a positive ion, or cation. Another atom, typically a non-metal, is able to acquire the electron(s) to become a negative ion, or anion.

An aqueous solution of glycerol, c3h8o3, is 48.0% glycerol by mass and has a density of 1.120 g ml-1. calculate the molality of

garik1379 [7]

Answer is: <span>the molality of the glycerol solution is 10.03 m.
V(solution) = 100 mL.
m</span>(solution) = V(solution) · d(solution).
m(solution) = 100 mL ·1.120 g/mL.
m(solution) = 112 g.
m(glycerol) = ω(glycerol) · m(solution).
m(glycerol) = 0.48 · 112 g.
m(glycerol) = 53.76 g.
m(water) = 112 g - 53.76 g.
m(water) = 58.24 g ÷ 1000 g/kg = 0.05824 kg.
n(C₃H₈O₃) = m(C₃H₈O₃) ÷ M(C₃H₈O₃).
n(C₃H₈O₃) = 53.76 g ÷ 92 g/mol.
n(C₃H₈O₃) = 0.584 mol.
b(C₃H₈O₃) = n(C₃H₈O₃) ÷ m(H₂O).
b(C₃H₈O₃) = 0.584 mol ÷ 0.05824 kg.
m(C₃H₈O₃) = 10.027 mol/kg.

Explain the main concept behind the VSEPR theory of molecular shape. How do both number and type of electron pairs influence the

vazorg [7]

According to the VSEPR hypothesis, each atom in a molecule will develop a shape that reduces the repulsion between its valence shell electrons.

<h3>What is the basis of VSEPR theory?</h3>

According to the valence-shell electron pair repulsion model, or VSEPR model, a molecule will modify its structure to maintain the greatest feasible distance between the valence electron pairs (based on the repulsive behavior of electron pairs). Given that negatively charged electrons repel one another, this makes sense.

<h3>How do both the number and type of electron pairs influence the shape of a molecule?</h3>

Electron pairings resemble groups of individuals who don't get along. They "like" to keep a safe distance between one another. Because carbon has only two electron domains, the molecular geometry of carbon dioxide is linear.

They consequently position themselves in the molecule as far apart as they can. This is how the molecule geometry is influenced by the number of electron domains.

Sulfur tetrafluoride is a trigonal bipyramidal molecule with four bonded and one non-bonding electron pair, or domain. The "shared" region between the two atoms is where the electrons in a covalent bond are most likely to be located. They become high electron density, compact zones as a result.

On the other hand, non-bonding electrons in a molecule's electron cloud are more "free" to "spread out." As a result, they are less dense and occupy a greater volume than bonding domains.

Therefore, what affects the geometry in a molecule is the "size" of a domain and the "desire" for electrons to be as far apart as feasible.
