The correct answer is A. Glass does not have an orderly arrangement of the atoms, like the minerals. Glass lacks a crystal lattice structure, and is an amorphous solid. The atoms of glass are rigidly fixed but are arranged in an orderly fashion.

Glass is different from a mineral because it $\boxed{{\text{a}}{\text{. does not have atoms arranged in an orderly pattern}}}$ .

Further Explanation:

The naturally occurring substances that are present in the earth’s crust are known as minerals. These are widely used in batteries, nuclear fuels, aircrafts, automobiles, and textiles. Quartz, calcite, and mica are some examples of minerals.

Glass is a solid that is formed by cooling the molten material such that the internal arrangement of atoms become disordered and is similar to that of liquid. It is a non-crystalline amorphous solid that is mainly composed of silicon dioxide $\left( {{\text{Si}}{{\text{O}}_{\text{2}}}} \right)$ . It is a hard and brittle solid and has the ability to reflect, refract and transmit light. It is used to manufacture lenses and windows. It shows high resistance to any chemical attack.

Since glass is an amorphous solid, it has random and disordered arrangement of atoms. So its atoms are not arranged in an orderly pattern. Therefore option a is correct.

What physical meaning is attributed to ψ², the square of the wave function?

Zigmanuir [339]

Answer:

The probability density (ψ2)

Explanation:

Indicates the probability of finding the electron in a certain region of space when it is squared ψ2.

This means that define2 defines the distribution of electronic density around the nucleus in three-dimensional space; a high density represents a high probability of locating the electron and vice versa.

The atomic orbital, can be considered as the electron wave function of an atom.

APPLICATIONS:

1.- Specify the possible energy states that the electron of the hydrogen atom can occupy and identify the corresponding wave functions medio, by means of a set of quantum numbers, with which an understandable model of the hydrogen atom can be constructed.

2.- It does not work for atoms that have more than one electron, but the problem is solved using approximation methods for polyelectronic atoms.

Key words how atoms work?

pantera1 [17]

Most atoms have three different subatomic particles inside them: protons, neutrons, and electrons. The protons and neutrons are packed together into the center of the atom(which is called the nucleus) and the electrons, which are very much smaller, whizz around the outside. Most of an atom is empty space.

Please help!!

Olegator [25]

Molarity = Moles/Liter

Use the molecular atomic mass of NaCl to convert from grams to moles.
Molecular mass of NaCl is the sum of its atomic masses. Look at the periodic table to find these. Na is 23 g/mol and Cl is 35.5 g/mol ,
so NaCl = 23 + 35.5 = 58.5 g/mol

multiply to cancel out grams
76 g NaCl * (1mol / 58.5 g NaCl) = 1.3 mol NaCl

over 1 Liter is just 1.3 M NaCl
Hope this helps!

Use the given data at 500 K to calculate ΔG°for the reaction

Anton [14]

Answer : The value of $\Delta G^o$ for the reaction is -959.1 kJ

Explanation :

The given balanced chemical reaction is,

$2H_2S(g)+3O_2(g)\rightarrow 2H_2O(g)+2SO_2(g)$

First we have to calculate the enthalpy of reaction $(\Delta H^o)$ .

$\Delta H^o=H_f_{product}-H_f_{reactant}$

$\Delta H^o=[n_{H_2O}\times \Delta H_f^0_{(H_2O)}+n_{SO_2}\times \Delta H_f^0_{(SO_2)}]-[n_{H_2S}\times \Delta H_f^0_{(H_2S)}+n_{O_2}\times \Delta H_f^0_{(O_2)}]$

where,

$\Delta H^o$ = enthalpy of reaction = ?

n = number of moles

$\Delta H_f^0$ = standard enthalpy of formation

Now put all the given values in this expression, we get:

$\Delta H^o=[2mole\times (-242kJ/mol)+2mole\times (-296.8kJ/mol)}]-[2mole\times (-21kJ/mol)+3mole\times (0kJ/mol)]$

$\Delta H^o=-1035.6kJ=-1035600J$

conversion used : (1 kJ = 1000 J)

Now we have to calculate the entropy of reaction $(\Delta S^o)$ .

$\Delta S^o=S_f_{product}-S_f_{reactant}$

$\Delta S^o=[n_{H_2O}\times \Delta S_f^0_{(H_2O)}+n_{SO_2}\times \Delta S_f^0_{(SO_2)}]-[n_{H_2S}\times \Delta S_f^0_{(H_2S)}+n_{O_2}\times \Delta S_f^0_{(O_2)}]$
