Why do covalent bonds have low conductivity and low melting and boiling points? Why will MgBr2 dissociate in water? How many hydrogen bonds can a single water molecule form? How does a polar covalent bond differ
Why does neon not form covalent bonds?Covalent Bond:A covalent bond is formed by sharing electrons mutually between two or more atoms. In order to complete the octet of each element, the electrons are shared between the individual atoms to form a covalent bond. A water molecule is an ...
1.5. If the bond in a diatomic molecule has 60% covalent character, what does this tell us about the atoms that make up the molecule? Calculate the molecular weight of a polyvinyl chloride molecule with a degree of polymerizati...
- According to Fajans' rules, smaller cations with higher positive charges have greater polarizing power. - Sn4+ has a greater polarizing power than Sn2+ because it is smaller and has a higher charge. 5. Covalent vs. Ionic Character: - Greater polarizing power means that Sn4+ can distort...
Why does NaF have a higher melting point than NaI? Briefly explain at the molecular level why a higher temperature might increase the production of carbon dioxide by a chemical leavener? Why is rotation around a double bond not possible at room temperature?
What is a covalent bond and what are the important characteristics of covalent bonds? Why is lattice energy important in forming ionic bonds? Why does BeCl2 have a low melting point but SiO4 has a high melting point even though they both have covalent bonds between the ...
Covalently bonded materials have covalent bonds between their atoms. The covalent bonds are formed when electrons are shared by the atoms of two non-metals (either same or different). Answer and Explanation:1 In ionically or metallic bonded materials there are ...
Is sodium chloride an ionic or covalent bond? Is NaCl considered an electron or a compound? Why do noble gases have low boiling points? Why are ionic bonds stronger than covalent? Why does sodium iodide solution conduct electricity? In chemistry, what factor is generally responsible for high...
Does copper conduct more electricity than platinum? Why or why not? What qualities must a metal like Mg have to prevent oxidation of another metal? 3. Briefly explain why Al does not occur naturally as a free metal. Why do covalent compounds not conduct electricity?
- Cl2 - SO2 - P4 - RbCl - NOUsing electronegativities, predict whether the Pb-I bond will be ionic, polar covalent, or pure covalent.Why does BeCl2 have a low melting point but SiO4 has a high melting point even though they both have covalent b...
