The principal quantum number of the first d shell is three. The principal quantum number determines the size of the orbital. The secondary divides the shell into subshells called orbitals and designated by the letters s, p, d, f. From the sequence of the electron configuration, it can be seen that at a principal quantum number of three the d shell first appear.
In a phase diagram, the point at which the solid, liquid, and gas coexist simultaneously is called the TRIPLE POINT. There is a specified pressure and temperature at which the substance can exist in equilibrium with these three phases being present.
Solutes dissolve in solvents to form a solution. A saturated solution contains just as must solute as it can normally hold.
The solvent in the coffee solution is water and the rest of the chemicals dissolved in the solvent are called solutes. A solution is formed when a solute is dissolved in a solvent.
A saturated solution contains just as much solute as it can normally hold at a particular temperature while a supersaturated solution contains more solute than it can normally hold at a particular temperature.
A polar molecule contains covalent bonds between atoms having an electronegativity difference above 0.5. Such molecules are polar as electrons of the bond are drawn closer to the atom that is more electronegative.
According to Avogadro's law; 6.02 × 10^23 particles is referred to as one mole of particles.
A strong acid has a pH that may range from 0 - 3. A strong base has a pH of around 10 - 14. Water is a neutral substance and has a pH of 7.
From the information provided;
Number of moles of acid = 0.002 moles
Volume of solution= 2 L
Concentration of solution = number of moles/volume = 0.002 moles/2L = 0.001 M
pH = - log[H^+]
pH = - log[0.001 ]
pH = 3
From;
pH + pOH = 14
pOH = 14 - pH
pOH = 14 - 8.5
pOH = 5.5
pOH = - log[OH^-]
[OH^-] = Antilog[-5.5]
[OH^-] = 3.2 × 10^-6 M

Answer: 4.90
Explanation: The molal freezing point constant of C6H6 is 4.90 and its melting point is 5.51∘C. A solution of 0.816 g of a compound A dissolved in 7.5 g of benzene freezes at 1.59∘C. Calculate molecular weight of compound A
no
its kinematics
the acceleration due to gravity and the initial vertical velocity are the only thing that affects vertical distance
