Based on location in the periodic table, fluorine (F) has chemical properties that are most similar to iodine.
In the periodic table, elements are classified in groups and periods. The elements in the same group are chemically similar and they have the same number of valence electrons. Elements in the same period have the same highest energy level.
Hence, when looking for an element that is most chemically similar to iodine, we have to consider the element that is in the same group with iodine.
Both fluorine are iodine are both in group 17 hence, fluorine is most chemically similar to iodine.

Answer:
2.6 mole of lithium bromide have 225.81 g.
Explanation:
Given data:
Number of moles of lithium bromide = 2.6 mol
Mass of lithium bromide = ?
Solution:
Formula:
<em>Number of moles = mass/ molar mass</em>
Molar mass of lithium bromide = 86.85 g/mol
Mass = number of moles × molar mass
Mass = 2.6 mol ×86.85 g/mol
Mass = 225.81 g
Thus 2.6 mole of lithium bromide have 225.81 g.
The extent of dissociation into hydrogen ions in water. A strong acid dissociates completely into hydrogen ions in water whereas a weak acid only dissociates partially
Answer:
6.14 L
Explanation:
To answer this question we'll<u> use the PV=nRT formula</u>, where:
- R = 0.082 atm·L·mol⁻¹·K⁻¹
- T = 17.6 °C ⇒ 17.6 + 273.16 = 209.76 K
We <u>input the data</u>:
- 0.97 atm * V = 0.25 mol * 0.082 atm·L·mol⁻¹·K⁻¹ * 209.76 K
And <u>solve for V</u>:
