The small, but important, energy differences between 3s, 3p, and 3d orbitals are due mainly to Heinsberg uncertainty principle

The s orbital always has a slightly lower energy than p orbital at the same energy level and so the s orbital always fill with electron before the corresponding p orbital do and the position of the 3d orbital and a small but important differenced between these 3s 3p and 3d are due to the  Heinsberg uncertainty principle and their principal quantum numbers ones rule and the numbers of weapons that can hold the penetration effect

And the electron in the 3s orbital is more likely to be close to the nucleus than is an electron in 3p orbital and the electron in 3p orbital in turn has a greater probability of being close to the nucleus than does one 3d  orbital

The hydrated ions are free to move around when ionic salts dissociate in aqueous solutions. Their movement, however, is random, and there is no charge.

After separating a solid substance into its ions, the ions are ready for reactions. When a compound is solid, the ions are held together by electrostatic attractions. To allow ions to move freely, it must first be dissolved in solution. Consider the reaction between sodium chloride and silver nitrate. Both of these compounds are commonly available in solid form. First, you would dissolve both solids in a solution, in this case water. (See Equations 1 and 2)

Once the solid has dissolved and separated into its ions in solution, these ions are ready to react in the chemical reaction (Equation 3).

Keep in mind that the AgNO3(aq) and NaCl(aq) reactants demonstrate that the ions are in solution. In other words, AgNO3(aq) is the same as Ag+(aq)+NO3(aq), and NaCl(aq) is the same as Na+(aq)+Cl (aq). The equation in Equation 3 represents a double displacement reaction, which means that cations in the reactants exchange anions to form the products. A precipitate is formed in the laboratory that we identify as silver chloride.

Answer:

answer below

Explanation:

The atomic structure primarily affects the chemical, physical, thermal, electrical, magnetic, and optical properties. The properties of a material offer clues as to the structure of the material. The strength of metals suggests that these atoms are held together by strong bonds.

When acid is added to pure water, the pH increases, and when base is added to pure water, the pH decreases.

A pH scale is the scale that is used to determine the amount of acidic or basic behavior in an aqueous solution. The pH scale is expressed as negative of the concentration of H⁺ or Hydronium ions. The scale has numeric values from 0 to 14. The solution having a value of 0 to 6 on pH scale will be acidic and solution having value of 8 to 14 will be basic in nature. The solution having value equal to 7 will be neutral. Whenever in an acidic or basic solution water is added, it becomes diluted solution. Adding water in an acidic solution makes the solution loose its acidic nature and moves towards basic nature that is pH increases and adding water in basic solution makes solution loose its basic nature and move towards acidic nature that is pH decreases.

11/10 MgL work has been done by the tension in the string.  If the object has been raised a distance l from rest.

The definition of work is expanded so that it encompasses both the forces applied to the body and the overall displacement of the body. A constant force F is present before this block. The objective of this force is to move the body d meters in a straight line in the force's direction.

Given,

Mass of object, M

Acceleration of object, a = g/10

Distance covered vertically, L

Tension of string, T

Work done by tension in string, W

W = T × L

By applying equilibrium force on string,

T - Mg = Ma

g = gravitational acceleration

T - Mg = M (g/10)

T = M(g/10) + Mg

T = 11/10 Mg

By substituting the value in, W = T × L

A 0. 600 g sample of a compound of arsenic and oxygen was found to contain 0. 454 g of arsenic. The empirical formula of a compound is As₂O₃.

The mass of a oxygen in the compound is

Mass of O=(Sample mass-Mass of As)

=(0.600-0.454)g

=0.146 g

The atomic mass of arsenic(As) is 75 g/mol and of oxygen(O) is 16 g/mol. Hence moles of oxygen and arsenic are

Moles of As=0.454 g×(1 mol/78 g)

moles of As=0.006053 mol

Moles of O=0.146 g×(1 mol/16 g)

moles of O=0.009125 mol

Divide both moles by 0.006053 mol

moles of As=(0.006053/0.006053)=1

moles of O=(0.009125/0.006053)=1.508≈1.5

Since we cannot take fractional moles in a compound. Hence multiply by 2 to both values of moles

moles of As=(1×2)=2

moles of O=(1.5×2)=3

Since 2 and 3 are values in the subscript of the As and O. Hence, the empirical formula is As₂O₃.
