Answer:
Metallic bonding
Explanation:
Metallic bonding
These type of bonding is observed between the delocalized electrons and the metal cations and is a form of electrostatic bond .
The substance that show these type of bonding , i.e. ,metallic bonding are malleable in nature , because ,
These substance can be moulded to give various shapes ,
As, the layers of atoms can slide on each other and therefore shows the property of malleability.
Hence, from the given information of the question ,
The correct type of bonding is metallic bonding.
Answer:
495 pm (see the relationship between the edge length (a) and radius (r) of atoms in attachment).
Explanation:
A <em>crystalline solid</em><em> possess rigid and long-range order; its atoms, molecules, or ions occupy specific positions</em>. A <em>unit cell</em><em> is the basic repeating structural unit of a crystalline solid</em>. Each sphere in the unit cell represents an atom, ion, or molecule and is called a <em>lattice point</em>. <u>The way the spheres are arranged in layers determines what type of unit cell we have.</u>
In the face-centered cubic cell, there are <u>spheres at the center of each of the six faces of the cube</u>, in addition to the eight corner spheres (see the second picture in the attachment). Each sphere in this arrangement is said to have a coordination number of 12 since each sphere is in contact with six spheres in its own layer, three spheres in the layer above, and three spheres in the layer below. The <em>coordination number</em><em> is defined as the number of atoms (or ions) surrounding an atom (or ion) in a crystal lattice</em>.
In the first picture in the attachment we can see that the relationship between the atomic radius <em>r</em> and the edge length <em>a</em> face-centered cubic cell is:
a=√8*r
Therefore, the edge length will be √8*175 pm = 495 pm
The reaction rate of the SN1 reaction change if the electrophile is switched from the tertiary electrophile to a secondary electrophile will decrease.
SN1 exhibits substitution, nucleophilicity, and monomolecular reaction, and is expressed by the expression rate = k [R-LG]. This means that the rate-determining step of the mechanism depends on the degradation of a single molecular species. Multi-step reactions include intermediates and multiple transition states (TS).
The SN1 reaction is a nucleophilic substitution reaction in which the nucleophile replaces the leaving group (similar to SN2). However, the SN1 reaction is a single molecule. The rate of this reaction depends on the concentration of only one reactant.

I'm pretty sure it's Newton's
Answer:
The concentration of F₂in equilibrium is 4,93x10⁻₃M
Explanation:
For the reaction:
2 OF₂ ⇄ 2 F₂ + O₂
The equilibrium constant, k, is defined as:
k = [F₂]²[O₂] / [OF₂]²
If you have in equilibrium [OF₂] = 2,49x10⁻² and [O₂] = 1,58x10⁻²
The concentration of F₂ is:
6,19x10⁻⁴ = [F₂]²[1,58x10⁻²] / [2,49x10⁻²]²
2,43x10⁻⁵ = [F₂]²
<em>4,93x10⁻³ = [F₂]</em>
I hope it helps!
