Answer is: the number of ions produced in the dissociation of aluminium fluoride is 4.
<span>
Chemical dissociation of aluminium fluoride in
water:
AlF</span>₃(aq) →
Al³⁺(aq) + 3F⁻(aq).<span>
There are four ions, one aluminium cation and
three fluoride anions.
Aluminium has oxidation +3, because it lost
three electrons, to have electron configuration as noble gas neon and fluorine has oxidation -1, because it gain one electron to </span>have electron configuration as noble gas neon.
Answer:
3.02x10²⁴
Explanation:
To solve this problem we need to use <em>Avogadro's number</em>: It is the number of units (usually atoms or molecules, in this case it's trucks) contained in one mol: 6.023x10²³.
We <u>multiply the given number of moles times Avogadro's number</u>:
5 * 6.023x10²³ = 3.02x10²⁴
So five moles of trucks would be 3.02x10²⁴ trucks.
Hybridization occurs in the orbitals of a carbon atom participating in a triple bond with another carbon atom s p.
Hybridization, as associated with genomics, is the method in which two complementary unmarried-stranded DNA and/or RNA molecules bond together to shape a double-stranded molecule. The bonding is depending on the ideal base-pairing throughout the 2 single-stranded molecules.
The process of Hybridization wherein 1s and 3p orbitals of same element entails in blending and recasting and bureaucracy new hybrid orbital of equal electricity, symmetry, and precise orientation in area is referred to as as sp3 hybridization. formation of methane molecule is the instance .
A combination of s and p orbital fashioned in trigonal symmetry and is maintained. example of sp2 hybridized is: Ethylene sp3 Hybridization. This kind involves mixing of one 's' orbital and three 'p' orbital's of equal energy to provide a brand new hybrid orbital referred to as sp3.
Hybridization is the concept that atomic orbitals fuse to form newly hybridized orbitals, which in flip, affects molecular geometry and bonding residences. Hybridization is also a spread of the valence bond theory.

Correct Answer: option 4: <span>E and D show that the energy of the products is less than that of the reactants.
Reason:
For the reaction: Q + R </span>→ N + M
<span> (reactant) (product)
From the graph, it is clearly evitable that E represent energy of reactant, while D represents energy of products. Also, value of D is less as compared to E. This signifies that, products (N+M) has less energy as compared to reactants (Q+R). Also, the reaction is exothermic in nature.
