Answer:

Geologists agree that Devils Tower began as magma, or molten rock buried beneath the Earth’s surface. What they cannot agree upon are the processes by which the magma cooled to form the Tower, or its relationship to the surrounding geology of the area. Numerous theories have been suggested to explain how Devils Tower formed. Geologists Carpenter and Russell studied Devils Tower in the late 1800s and concluded that the Tower was formed by an igneous intrusion (the forcible entry of magma through other rock layers). Later geologists searched for more detailed explanations.

The simplest explanation is that Devils Tower is a stock—a small intrusive body formed by magma which cooled underground and was later exposed by erosion (Figure 1). In 1907, scientists Darton and O’Hara decided that Devils Tower must be an eroded remnant of a laccolith. A laccolith is a large, mushroom-shaped mass of igneous rock which intrudes between the layers of sedimentary rocks but does not reach the surface. This produces a rounded bulge in the sedimentary layers above the intrusion (Figure 2). This idea was quite popular in the early 1900s when numerous studies were done on a number of laccoliths in the American southwest.

Other ideas have suggested that Devils Tower is a volcanic plug or that it is the neck of an extinct volcano (Figure 3). The limited evidence of volcanic activity (volcanic ash, lava fows, or volcanic debris) in the area creates doubt that the Tower was part of a volcanic system. It is possible that this material may simply have eroded away. In 2015, geologist Prokop Závada and his colleagues proposed their own hypothesis for the formation of the Tower. They compared it to a similar butte formation in the Czech Republic. Their hypothesis suggests that the Tower is the result of a maar-diatreme volcano (Figure 4). These form when magma encounters groundwater beneath the Earth’s surface. The super-heated water becomes steam. This steam expands explosively creating a crater on the surface. The crater fills with lava which cools and solidifes into a dome structure. Erosion wears away portions of the dome to create the Tower as we see it today.

The concept of erosion exposing the Tower is common to all of its modern formation theories. Ironically, the erosion which exposed the Tower also erased the evidence needed to determine which theory of Devils Tower’s formation is the correct one.

Two substances, A and Z, are to be identified. Substance A can not be broken down by a chemical change. Substance Z can be broken down by a chemical change. What can be concluded about these substances?(1) Both substances are elements.
(2) Both substances are compounds.
(3) Substance A is an element and substance Z is a compound.
(4) Substance A is a compound and substance Z is an element.

Answers

Answer;

(3) Substance A is an element and substance Z is a compound.

Explanation;

-A compound is a substance formed when two or more chemical elements are chemically bonded together, such as water, carbon dioxide, methane, etc while an element is a pure chemical substance made of same type of atoms, such includes, oxygen, potassium, hydrogen, carbon, etc.

- Compounds can be brokendown or decomposed into simpler substances: elements cannot be broken down chemically into simpler substances .

The answer is (3) Substance A is an element and Z is a compound. The chemical reaction can only break the chemical bond but can not change the atom. So A will is an element.

Glycerol is a syrupy liquid often used in cosmetics and soaps. A 3.25-L sample of pure glycerol has a mass of 4.10 X 10^3 g. What is the density of glycerol in g/cm^3?

Answers

Answer: The density of glycerol will be $1.26cm^3$

Explanation:

Density is defined as the mass contained per unit volume.

$Density=(mass)/(Volume)$

Given : Mass of glycerol= $4.10* 10^3$ g

Volume of bromine = 3.25 L= $3250cm^3$ $(1L=1000cm^3)$

Putting in the values we get:

$Density=(4.10* 10^3g)/(3250cm^3)=1.26g/cm^3$

Thus density of glycerol will be $1.26cm^3$

The density of glycerol used in cosmetics and soaps is 1.26 g/cm³.

FURTHER EXPLANATION

Density is the measure of the compactness of a material. It is the mass per given volume. This can be expressed mathematically as:

$Density = (mass)/(volume)$ (equation 1)

To solve the problem, we first sort the given in the problem:

mass = 4.10 × 10³ g

volume - 3.25 L

The problem is asking for the density in units of g/cm³ which means that we must first convert the volume from liters to cm³.

$volume \ (in \ cm^3) = 3.25 \ L * (1000 \ mL)/(1 \ L) * (1 \ cm^3)/(1 \ mL)\nvolume \ (in \ cm^3) = 3250 \ cm^3$

Now we can plug in the values of mass and volume into equation 1:

$Density = (4.10 * 10^3 \ g)/(3250 \ cm^3)\n\nDensity = 1.2615 (g)/(cm^3)$

Since the given in the problem both have 3 significant figures, the final answer must also have three significant digits only. Therefore,

$\boxed {Density = 1.26 (g)/(cm^3)}$

The density of glycerol is greater than 1, so when mixed with water it will sink.

Which traits explain the differences between halogens and alkali metals? Select all that apply Question 5 options: Halogens are better oxidizing agents than their alkali metal counterparts within the same period. Halogens have a larger van der Waal's radii than their alkali metal counterparts within the same period. Halogens have a higher effective nuclear charge than their alkali metal counterparts within the same period. Halogens have a higher first ionization energy than their alkali metal counterparts within the same period. Halogens have a higher electron affinity than their alkali metal counterparts within the same period.

Answers

Answer:

Halogens are better oxidizing agents than their alkali metal counterparts within the same period

Halogens have a higher first ionization energy than their alkali metal counterparts within the same period.

Halogens have a higher electron affinity than their alkali metal counterparts within the same period.

Halogens have a higher effective nuclear charge than their alkali metal counterparts within the same period

Explanation:

Effective nuclear charge increases across a period and accounts for increase in ionization energy across a period. This explains why halogens in the same period with alkali metals have higher effective bucket charge as well as ionization energy than the alkali metals.

Similarly, electron affinity increased across a period, halogens have greater ekctron affinity than corresponding alkali metals in the same period.
