The reason Catholics do not eat meat on Fridays is in remembrance  of the day of Jesus Christ's sacrifice for all of humanity. It is a  form of penance to honor and worship â¦ God.    Note that many Catholics today believe that the Church allows them  to eat meat on Fridays except during Lent. This is not true.
Some compounds contain both ionic and covalent bonds. These compounds contain polyatomic ions. Many of these compounds contain a metal, a nonmetal and also hydrogen. However, other examples contain a metal joined via an ionic bond to covalently bonded nonmetals. Here are examples of compounds that exhibit both types of chemical bonding. Examples of Ionic Bonds-Ionic Compounds. Examples of Covalent Bonds-Covalent Compounds.
Answers. Best Answer: To have ionic bonds, your compound must have a metal. This eliminates A and C. To have covalent bonds, there must be bonding between 2 nonmetal atoms. This eliminates D. So the answer is B. Looking at the answers, though: A) COS is carbonyl sulfide, a molecule very similar to carbon dioxide.O4 (2-) is a sulfate anion, and it has sulfur-oxygen single bonds. These single bonds are shorter than normal sulfur-oxygen single bonds but longer than a sulfur-oxygen carbon bond. This phenomenon is called resonance. C) SF6 has entirely covalent sulfur-fluorine bonds and is octahedral.
