The reason for this is that in almost all ionic compounds, there is an equivalent transfer and acceptance of the same number of electrons, whereby each transfer results in a + and receiver is a -. This ultimately cancels out when the ions come close together.
Answer:
For example, atoms in Groups 1 and 2 have 1 and 2 valence electrons, respectively. Atoms in Groups 13 and 18 have 3 and 8 valence electrons, respectively. Valence electrons are responsible for the reactivity of an element. They determine how "willing" the elements are to bond with each other to form new compounds.
Explanation: it might be 18 my guess:)
Answer:
They are located in the equatorial positions
Explanation:
To know this, we need to draw the chair conformation of the cyclohexane.
As you can see in picture 1, we have a cyclohexane with the two methyl in position 1 and 3, both of them with a wedge bond meaning they are in cis position.
The next structure is the chair conformation of the 1,3-dimethylcyclohexane. Facing in cis position they could be either in axial positions (Facing upward) or equatorial positions (Facing to the sides).
Now both of them are in cis position, however, one of them is the most stable conformation. This one would be the equatorial positions. Why is that structure more stable than the axial positions? basically, because when you have a cyclohexane with radicals in position 1 and 3, you can have the 1,3-diaxial interactions which is an interation that is usually repulsive between those substituent. Therefore, this repulsion of the methyls, it's similar to steric hindrance and make this conformation being less stable than the conformation in the equatorial positions, because you can see there are no interaction there and no steric hindrance. Therefore the methyl groups should be located in the equatorial positions to do the most stable conformation. See picture attached.
Increasing the surface area of a reactant increases the frequency of collisions and increases the reaction rate. Several smaller particles have more surface area than one large particle. The more surface area that is available for particles to collide, the faster the reaction will occur.
Answer:
3rd law
Explanation:
when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
