Relate microscopic bonding properties to solid state properties

Answers

Answer 1

There are many factors that we can take into account when attempting to relate microscopic bonding properties to solid-state properties, for example, the rigid and immobile nature of solid states and their molecular bonds.

Solid-state properties are simply put, the properties we can observe and measure when studying an element in solid form. These solids have specific characteristics such as:

Structural rigidityThey do not change shapeDo not change the volume they occupy

and so on, which although not initially obvious, are caused by the microscopic molecular bonds of their atoms.

The microscopic properties of solids are very similar to that of the solid-state properties. The atoms of a solid are very close together and strongly bonded to one another, because of this the atoms form a very rigid structure that resists changes to their shape or volume, much like the macroscopic properties of the solid. This serves to show how these properties may cause the solid-state effects we can observe normally.

Suppose you are performing a precipitation titration to study the K sp of zinc(II) iodate, Z n ( I O 3 ) 2 . The literature value of K sp is 3.9 × 10 − 6 . If you use 0.200 M K I O 3 as the titrant, what concentration of I O 3 − (in M) do you predict will be needed to start precipitation in a 0.229 M solution of Z n ( N O 3 ) 2 ?

Answers

The predicted concentration of IO₃⁻ needed to start the precipitation titration is 1.703 × 10⁻⁷ M

The dissociation of zinc (II) iodate can be expressed as:

[tex]\mathbf{Zn (IO_3)_2 \to Zn^{2+} + 2IO_3^-}[/tex]

Given that the solubility product constant Ksp value = 3.9 × 10⁻⁶

For the above dissociation,

[tex]\mathbf{Ksp = [Zn^{2+ }] [IO_3^-]^2}[/tex]

Since [tex]\mathbf{ [Zn^{2+ }] = [Zn(NO_3)_2] = 0.229 \ M}[/tex]

[tex]\mathbf{3.9\times 10^{-8} =(0.229) \times [IO_3^-]^2}[/tex]

[tex]\mathbf{ [IO_3^-]^2 = \dfrac{3.9\times 10^{-8} }{(0.229)}}[/tex]

[tex]\mathbf{ [IO_3^-]^2 = 1.703 \times 10^{-7} \ M}[/tex]

Therefore, we can conclude that the initial predicted concentration of IO₃⁻ needed to start the precipitation titration is 1.703 × 10⁻⁷ M

Zingerone, one of the flavor molecules in ginger,
contains only C, H, and O. Combustion of 10.0 g
of zingerone produces 24.91 g of CO2 and
6.522 g of H20. Determine the molar mass of the
compound if it is between 150.0 and 220.0 g/
mol. Provide an answer to four significant
figures.

Answers

The molecular formula of the compound is C12H15O3 hence the molar mass of the compound is 207 g/mol.

We need to obtain the number of moles of carbon, hydrogen and oxygen in the compound;

Carbon = 24.91 g/44g/mol × 1 mole of carbon = 0.566 moles

Mass of carbon =  0.566 moles × 12 g/mol = 6.792 g

Number of moles of hydrogen = 6.522 g/18 g/mol × 2 moles = 0.725 moles

Mass of hydrogen = 0.725 moles  × 1 g/mol = 0.725 g

Mass of oxygen = 10 - (6.792 g + 0.725 g) = 2.483 g

Number of moles of oxygen = 2.483 g/16 g/mol = 0.155 moles

Now we must divide through by the lowest number of moles;

C - 0.566/0.155   H - 0.725/0.155     O - 0.155/0.155

C - 4                    H - 5                        O - 1

The simplest formula is C4H5O Recall that the molar mass of the compound lies between 150.0 and 220.0 g/mol

4(12) + 5(1) + 16 = 69

Hence; n = 3 and the molecular formula of the compound is C12H15O3

The molar mass of the compound is; 12(12) + 15(1) + 3(16) = 207 g/mol

Given that a single-displacement reaction occurred between two (2) reactants which were placed into a flask,  the potential identities of A, B, and X are: D. A = Mg, B = O, X = Cl.

A single-displacement reaction is also referred to as a single-replacement reaction and it can be defined as a type of chemical reaction wherein a single (one) chemical element of the reacting chemical compound is displaced (replaced) by a similar chemical element.

This ultimately implies that, a single-displacement reaction typically involves a single element displacing another chemical element within a chemical compound.

Note: A potential identity reveals the chemical symbol or name of a chemical element in a particular chemical reaction.

Given the following general reaction of scheme of:

                                     [tex]2AB+2X_2\rightarrow 2AX_2+B_2[/tex]

Answer:

respiration and photosynthesis

Explanation:

The percentages of carbon dioxide and oxygen in Earth's atmosphere are maintained most directly by cellular respiration and photosynthesis.

What is photosynthesis?

Photosynthesis simply refers to a biological and chemical process through which green plants convert light energy derived from the Sun into chemical energy, so as to make their food while using carbon dioxide (CO₂) and releasing oxygen.

On the other hand, cellular respiration is a series of metabolic reactions that occur in living cells and it involves the use of oxygen that are typically produced by green plants (autotrophs) during photosynthesis.

This ultimately implies that, the percentages of carbon dioxide (1%) and oxygen (20%) that are contained in Earth's atmosphere are maintained most directly by cellular respiration and photosynthesis.

acceleration?

Answers

Answer:

Answer: Change in speed = 11 m/sTime taken = 3.4sHence, acceleration = (11/3.4) m/s² = 3.235 m/s²

Explanation:

(winks and runs off)

Acceleration is 3.235 m/s² when Usain Bolt went from 0.0 to 11.0 m/s in 3.4 seconds.

What is acceleration?

Acceleration is defined as a rate at which the velocity changes with time with respect to both speed and direction.An object is said to be accelerated if it's speeds up r slows down.

Motion along a circle is always accelerated even when speed is constant it's direction is continuously changing.Acceleration is a vector quantity as it has both magnitude as well as direction.The magnitude of acceleration is described by Newton's second law of motion.

Formula of acceleration is change in speed /time.Substituting the given values in the given formula,(11.0-0.0)/3.4=3.235 m/s².

Thus, the acceleration  is 3.235 m/s² when Usain Bolt went from 0.0 to 11.0 m/s in 3.4 seconds.

Which best describes the energy change that takes place during deposition?
Heat energy released by the substance
Heat energy is maintained by the substance
Heat energy is slowly gained by the substance
Heat energy is quickly absorbed by the substance

Answers

Answer:

heat energy released by the substance

The energy change that takes place during deposition is that heat energy is released by the substance. This statement is true about deposition.

Deposition is a phase transition that occurs when a gas is converted directly to a solid without passing through the liquid state. During deposition, energy is released by the gas particles and absorbed by the surface, resulting in a decrease in the energy of the gas particles and an increase in the energy of the surface particles.As a result, the substance releases heat energy as it changes from a gas state to a solid state.

Therefore, the correct option is:Heat energy released by the substance.
