The fourth energy level, or shell, would contain four subshells, designated s, p, d, and f.
What are subshells?
A subshell is a set of atomic orbitals with the same value of the angular momentum quantum number (l) and the same magnetic quantum number (m_l). Subshells are characterized by the letter s, p, d, f, etc., which corresponds to the value of l.
The fourth energy level, or shell, would contain four subshells, designated s, p, d, and f. The number of subshells in a given energy level is determined by the value of the principal quantum number (n).
Each subshell is designated by a letter, s, p, d, f, etc., which corresponds to the angular momentum quantum number (l). The value of l can be used to determine the number of subshells in a given energy level.
For example, l = 0 corresponds to an s subshell, l = 1 corresponds to a p subshell, l = 2 corresponds to a d subshell, and l = 3 corresponds to an f subshell. The principal quantum number of 4 shell is 4, so the value of l can be 0,1,2,3. Hence it contains 4 subshells.
Hence, the fourth energy level, or shell, would contain four subshells, designated s, p, d, and f.

how many hydroxide ions are present in 509 grams of copper ii hydroxide ?
The number of hydroxide ions, OH⁻ present in 509 grams of copper (ii) hydroxide, Cu(OH)₂ is 6.28×10²⁴ ions
How do I determine the number of ions?We'll begin by obtaining the mole of copper (ii) hydroxide, Cu(OH)₂. Details below:
Mass of Cu(OH)₂ = 509 gramsMolar mass of Cu(OH)₂ = 97.56 g/molMole of Cu(OH)₂ = ?Mole = mass / molar mass
Mole of Cu(OH)₂ = 509 / 97.56
Mole of Cu(OH)₂ = 5.22 moles
Next, we shall determine the mole of OH⁻ in 5.22 mole of Cu(OH)₂. This is shown below:
Cu(OH)₂(aq) <=> Cu²⁺(aq) + 2OH⁻(aq)
From the above equation,
1 mole of Cu(OH)₂ contains 2 moles of OH⁻
Therefore,
5.22 moles of Cu(OH)₂ will contain = 5.22 × 2 = 10.44 moles of OH⁻
Finally, we shall determine the number of ions of OH⁻. Details below:
From Avogadro's hypothesis,
1 mole of OH⁻ = 6.02×10²³ ions
Therefore,
10.44 moles of OH⁻ = 10.44 × 6.02×10²³

The volume of oxygen required for the complete combustion of 0.828 L of propane at STP is 4.14 L.
What is a combustion reaction?A combustion reaction is a high-temperature exothermic redox chemical reaction that occurs when an oxidant, typically atmospheric oxygen, interacts with a fuel to generate oxidized, frequently gaseous products in a mixture known as smoke.
The volume of oxygen is required to completely combust 0.828 L of propane (C₃H₈) at STP is determined from the mole ratio of the reaction as given by the equation of the reaction below:
C₃H₈ (g) + 5 O₂ (g) → 3 CO₂ (g)+ 4 H₂O (g)
The mole ratio of propane to oxygen is 1 : 5
Hence, 5 moles of oxygen are required for the complete combustion of 1 mole of propane.

When a vanadium sample's measured density at room temperature is 6.9 g/cm3, we can infer that there is a 13% error in the measurement when compared to the true value of 6.1 g/cm3 (Option C).
Vanadium is found to have a density of 6.9 g/cm3 at room temperature in a laboratory experiment.
Vanadium has a 6.1 g/cm3 density at room temperature, per the literature. The actual value is this.
The following expression can be used to calculate the measurement's percent error.
ε = [tex]\frac{experimental value - true value }{true value}[/tex] x 100
Thus when a vanadium sample's measured density at room temperature is 6.9 g/cm3, we can infer that there is a 13% error in the measurement when compared to the true value of 6.1 g/cm3 (Option C).
