Answer:
The coordination number.
Explanation:
The coordination number is defined as the number of atoms surrounding an atom in a crystal lattice and indicates how tightly the atoms are packed together.
Coordination number is also known as ligancy in chemistry and it basically refers to the total or overall number of neighboring ions, atoms or molecules with respect to a central atom in a crystal lattice. The term coordination number was first defined by the notable and amiable Swiss chemist by the name, Alfred Werner in 1893.
Generally, the coordination number of an atom in a crystal lattice can have a minimum value of two (2) and a maximum value of sixteen (16). It is usually determined by the size of the ligands, central atom and the charge associated with the electronic configuration of an ion. For example, the coordination number of carbon in methane (CH4) is four (4) because an atom of carbon has four (4) atoms of hydrogen bonded to it.
In the ground state, only one. But for bonding, all three valence electrons are used, and the atom acquires a slightly excited state.
Answer:
kinetic energy decreases
Explanation:
kinetic energy usually increases when hot and decreases when cold. The steam is turning into a liquid because it is cooling down, causing the molecules to move less and slow down.
Answer:
Explanation:
585.2 meters per minute in 32 feet per second To convert any value in feet per second to meters per minute, just multiply the value in feet per second by the conversion factor 18.288. So, 32 feet per second times 18.288 is equal to 585.2 m/min.
Answer:
k = 3.2 x 10¹¹
Explanation:
The equilbrium taking place is:
- N₂(g) + 3Cl₂(g) ↔ 2NCl₃(g)
And the expression for the equilbrium constant <em>k</em> is
- k = [NCl₃]² / ( [N₂] * [Cl₂]³)
We are given all the required data from the problem, so now we <u>solve for k</u>:
- k = (1.9x10⁻¹)² / ( (1.4x10⁻³) * (4.3x10⁻⁴)³ )
