which solids will melt under applied pressure? check all that apply.

Answers

The answer for this question is ice

According to the forces of attraction , ice is a solid which will melt under applied pressure.

What are the  forces of attraction?

Forces of attraction  is a force by which atoms in a molecule  combine. it is basically an attractive force in nature.  It can act between an ion  and an atom as well.It varies for different  states  of matter that is solids, liquids and gases.

The forces of attraction are maximum in solids as  the molecules present in solid are tightly held while it is minimum in gases as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.

The physical properties such as melting point, boiling point, density  are all dependent on forces of attraction which exists in the substances.

why is it important to select a good stationary phase

Answers

Selectivity is relatively easy to alter, with mobile phase composition and stationary phase being the primary means of adjustment. The hydrophobicity, polarity and nature of the chosen stationary phase all play a crucial role in analyte interaction and directly affect the selectivity of a separation.

In chromatography, it is important to select a good stationary phase so as to ensure proper separation of components.

What is chromatography?

Chromatography is a separation technique which is generally used for separating substances based on their solubilities. The technique makes use of two phases the mobile phase and the stationary phase.

The components are separated from each other based on their solubility in the mobile phase. Component which is least soluble does not travel along the mobile phase while component which is highly soluble travels with the mobile phase.

The difference in the solubility of the components is measured with the reference to the solvent front and is expressed in terms of Rf value.Chromatography finds application in forensics, separation of organic compounds,etc.

Explanation:

The molar mass of sulfur S is 32.06 g/mol
Calculate the mass in grams of a sample of S containing 2.01x10^24 atoms
Help Please<3

Answers

Answer: 107.01 g

Explanation:

Since we are starting from the number of atoms of Sulfur, we need to know two sets of formulas:

mass  = moles × molar mass moles = atoms ÷ Avogadro's Number

        ⇒ mass = (atoms ÷ Avogadro's Number) ×  molar mass

  mass = [(2.01 × 10²⁴ atoms) ÷ (6.022 × 10²³ atoms/mole)] × (32.06 g/mol)  

            = 107.01 g

the mass of a sample of S containing 2.01×10²⁴ atoms is 107.01 g.

The molar mass of sulfur S is 32.06 g/mol, then the mass in grams of a sample of S containing 2.01x10^24 atoms  is 107.01 g

what is molar mass ?

The molar mass can be defined as the weight of one sample mole, by Multiplying  the subscript means  the number of atoms times that element’s atomic mass and add the masses of all the elements in the molecule to obtain the molecular mass.

Molar mass is  expressed in either gram ( g) or kilograms (kg).

Mass  = moles × molar mass

moles = atoms ÷ Avogadro's Number

       ⇒ mass = (atoms ÷ Avogadro's Number) ×  molar mass

 mass = [(2.01 × 10²⁴ atoms) ÷ (6.022 × 10²³ atoms/mole)] × (32.06 g/mol)  

          = 107.01 g

Which of the three objects has the greatest density? Why? (GOLD BARS/GOLD COINS/GOLD CHAIN)

Answers

Answer:

They all have the same density

Explanation:

Density is an intensive physical property, meaning that as long as the chemical formula is the same, that specific intensive physical property will be the same. For example. One kilogram of feathers has the same mass as one kilogram of bricks. Why? They both have a mass of one kilogram.

It's the same thing here. Since all the objects are (assumed to be) made up of 100% gold, they would all have the same density regardless of the mass. For extra points, say the density of each object is [tex]19 \frac{g}{cm^3}[/tex].

how do the melting points of enantiomers compare to each other? how do the melting points of diastereomers compare to each other?

Answers

Melting points of enantiomers will not compare to each other as they have same M.P. and Diastereoisomers are compared on the basis of melting point.

What are steroisomers?

Stereoisomers are those isomers which are having the same molecular formula but different spatial arrangemet of atoms within the molecule.

Enantiomers: Enantiomers are pair of two stereoisomers which are having mirror image of each other, but are not superiposable. They have the same melting point so we can not compare enantiomers on the basis of their melting point.Diastereoisomers: Diastereoisomers are pair of those stereoisomers which are not having mirror image of each other, but are superimposable.They have different physical and chemical properties, so it can be compared on the basis of melting point.

Hence, only diastereoisomers are compared on the basis of melting point.

Rocks formed from magma under Earth’s surface have larger grains than rocks formed from lava on Earth’s surface. This is because magma cools slower underneath the ground than it does above ground.

What kind of rock is this?
A.Igneous
B.Metamorphic
C.Sedimentary


Where would this rock most likely be formed?
A. Along the sides of a volcano
B. On the ocean floor"

What are igneous rocks?

Igneous rocks are one of the three main rock types the other two including sedimentary and metamorphic rocks.These rocks are formed by cooling and solidification of lava or magma.

The magma is derived from partial melts in the planet's mantle or crust.Melting is caused by increase in temperature or decrease in pressure or even change in composition.Solidification occurs either below surface which is called as intrusive rocks or on the surface as extrusive rocks.

They are classified according to their texture,mode of occurrence,chemical composition,geometry and mineralogy of rock.The two important variables for classification are mineral composition and cooling history.

4) Atoms of a particular element are identical. They have the same mass and volume.

Postulates of modern atomic theory:

1) All matter is composed of atoms.

2) Atoms consist of protons, electrons and neutrons.
