4.5 L
Explanation:
We will use the combined gas law formula;
P₁V₁/T₁ = P₂V₂/T₂
Because the pressure remains the same, it cancels out and what remains is;
V₁/T₁ = V₂/T₂
Before evaluating remember to change the temperatures into Kelvin;
-23° = 250.15 K
177° = 450.15 K
We replace the variables with known values;
2.5 / 250.15 = V₂ / 450.15
V₂ = 2.5 /250.15 * 450.15
V₂ = 4.4988 L
≅ 4.5 L
Time such as minutes, days, and months will always be a(n)....... INDEPENDENT variable
Ksp, the product of solubility constant is given by the product of the concentrations in the equilibrium of the species on the right hand of the equillibrium reaction, each raised to a power that is its coeffiicient in the equillibrium reaction.
So you must start by writing the equilibrium reaction:
Fe(OH)3 (s) ----> Fe(3+) aq + 3 (OH-) aq
Now you can state the formula for the Ksp
=> Ksp = [Fe (3+) aq] [OH-]^3
So, the answer is the third option of the list.
The "sea of instability" refers to a region of elements on the periodic table that are highly unstable. These elements have extremely short half-lives that may be measured in micro- or nanoseconds. (A nanosecond is the time it takes for light to travel one foot.) This region of unstable elements surrounds the island of stability.
Answer:
These properties are basically the inverse of each other.
Explanation:
- Electronegativity is the tendency of an atom to attract an electron and make it a part of its orbital.
Ionization enthalpy, is the energy required to remove an electron from an atom.
- More electronegative atoms have high ionization enthalpies If the energy required to remove an electron is less, i.e. the atom has more tendency to give electron, it would thus have less tendency to take electron.
- Values and tendency of electronegativity in the periodic table: In general, the electronegativity of a non‐metal is larger than that of metal. For the elements of one period the electronegativities increase from left to right across the periodic table. For the elements of one main group the electronegativities decrease from top to bottom across the periodic table. To the subgroup elements, there’s no regular rule.
- Values and tendency of ionization potential in the periodic table: The first ionization energy is the energy which is required when a gaseous atom/ion loses an electron to form a gaseous +1 valence ion. The energy which is required for a gaseous +1 valence ion to loose an electron to form a gaseous +2 valence ion, is called the second ionization energy of an element. In general, the second ionization energy is higher than the first ionization energy of an element.
The first ionization energies of the elements of one period increase from the left to the right across the periodic table. According to the elements of main group, the first ionization energies generally decreases from top to bottom across the periodic table.
