1) Based on their position on the periodic table, which bond do you expect to be the most polar? Al---P Al---S Be--Cl P--Cl 2) Each scenario describes the properties of a substance. Based on the properties determine if the substance is a Non-acid/Non-base covalent substance, metallic substance, Acid or base covalent substance, or Ionic Substance. Substance A: Melts at 520 degrees celsius. Decomposes before it can boil. Does not conduct electricity in the solid or liquid state or in aqueous...
Which of the following processes would you expect to produces the greatest increase in the entropy of a pure substance that is heated from absolute zero to a temperature somewhat above its boiling point. heating the liquid melting the solid heating the gas heating the solid vaporizing the liquid
answers to #8 and #9 1 pts D Question 8 Why isn't lattice energy measured for covalent compounds? Covalent compounds form a lattice that is different than ionic compounds and thus another measure is used. Covalent compounds don't form the lattice structure that ionic compounds do. Covalent compounds do not satisfy the octet rule and thus do not have lattice energies. OCovalent compounds have high lattice energies and cannot be measured. Question 9 1 pts Which of the following ionic...
