Answer:
(f - g)(2) = -6
Step-by-step explanation:
(f - g)(2) = (-2x + 8) - 5x, where x=2
= (-2(2) + 8) - 5(2)
= (-4 + 8) - 10
= 4 - 10
= -6
(f - g)(2) = -6
Answer:
The two most basic types of bonds are characterized as either ionic or covalent. In ionic bonding, atoms transfer electrons to each other. ... In short, atoms with the same electronegativity share electrons in covalent bonds, because neither atom preferentially attracts or repels the shared electrons.
Hope this helps.....

In the reaction, Na⁺ + 6H₂O ⇆ Na (H₂O)⁺₆, Na⁺ is a Lewis acid and H₂O is a Lewis base.
<h3>
What is a Lewis acid-base reaction?</h3>
- According to the Lewis theory of acid-base reactions, acids accept pairs of electrons and bases donate pairs of electrons.
- Any substance like H+ ion, which is capable of accepting a pair of nonbonding electrons or an electron-pair acceptor is known as a Lewis acid.
- Any substance, like the OH- ion, that is capable of donating a pair of nonbonding electrons or an electron-pair donor is a Lewis base.
- Here Na⁺ that is electron deficient accepts electrons from the electron donor, H₂O
- From the Lewis theory, with no change in the oxidation numbers of any atoms, acids react with bases to share a pair of electrons.
