How do covalent compounds differ from ionic compounds?

Chemistry
1 answer:
Bad White [126]3 years ago
5 0

Answer:

1. Ionic bonds result from transfer of electrons, but covalent bonds are formed by sharing.

2. Ions are arranged in a three-dimensional array (like crystals). Covalently bonded substances exist as discrete molecular units.

3. Ionic compounds often dissociate into ions in solution, but covalently bonded molecules retain their molecular identity in solution.

Hope this helps :)

U-238 has _____ protons and 146 neutrons
qaws [65]
U-238 
The number besides the U means its total molar mass. The molar mass of this element is 238
Molar mass= protons + neutrons
This means that 238= 146 + protons
Do 238 - 146

Reika [66]

Linking monomers together to form a polymer .This chemical reaction also forms water molecules.

<h3>What is Polymerization?</h3>

This is a type of reaction which involves the linking of two or more monomers to form a polymer.

Dehydration reaction forms water molecules as part of the product thereby making it the most appropriate choice.

The pKa of the α‑carboxyl group of serine is 2.21 , and the pKa of its α‑amino group is 9.15 . Calculate the average net charge
sleet_krkn [62]

Answer:

Net charge in serine at pH equal to 8.30 is "0"

Explanation:

  • At pH > pK_{a}, carboxyl group exists as -CO_{2}^{-} (charged)
  • At pH < pK_{a}, carboxyl group exists as -COOH (neutral)
  • At pH > pK_{a}, amino group exists as -NH_{2} (neutral)
  • At pH < pK_{a}, amino group exists as -NH_{3}^{+} (charged)
  • So, at pH = 8.30, both carboxyl and amino group exists in charged state.
  • Net charge in serine at pH equal to 8.30 is "0".
  • Structure of serine at pH equal to 8.30 has been shown below.
