I think its Ionic because Cr is a metal and S is a non-metal, but when trying to verify online I'm getting multiple answers. Carbon dioxide, or CO2, forms a covalent bond. H2S. 6) Carbon disulphide, covalent. definitely covalent.covalent bonds are bonds between non-metals while ionic bonds are those between a metal and a non-metal.covalent bonds emphasise the sharing of electrons.both nitrogen and oxygen are non-metals thus they form covalent bonds. The resulting compound carries a neutral electrical charge. ionic What is the formula for this compound? 7) Phosphorus pentoxide, covalent. What was the Standard and Poors 500 index on December 31 2007? Classify the compound sulfur dioxide as ionic or covalent covalent What is the formula for this compound? Why don't libraries smell like bookstores? Who was prime minister after Winston Churchill? The reason for this fact, is that ionic compounds require a huge amount of energy to break their ionic bonds, and pull apart the positive and negative charges. • Examples: Mg(OH)2: magnesium hydroxide, KCN: potassium cyanide, Li2CO3: lithium carbonate, KNO3: potassium nitrate. a) Ti(SO4)2 b) CO c) CuCO3 d) HClO e) HClO3 f) HF g) Cr2S3 h) N2O5 i) AgNO3 j) HClO2 k) U(PO4)2 l) CuNO3 m) HBr n) SF4 o) VN 2) Write the formulas for each of the following compounds (note: first decide whether they are ionic or covalent). Who is the longest reigning WWE Champion of all time? What is the conflict of the story sinigang by marby villaceran? 4) Phosphorus trichloride, covalent. When did Elizabeth Berkley get a gap between her front teeth? Nonmetals bond to each other via covalent bonds while oppositely charged ions, such as metals and nonmetals, form ionic bonds.Compounds which contain polyatomic ions may have both ionic and covalent bonds. Chromium oxide (Cr2O3) is an ionic compound, since it is made up of a metal and a nonmetal. From the molecules that make up your body and the salt you put on your food to the chair youre sitting on, covalent and ionic bonds hold matter together in the forms we interact with on a day-to-day basis. A) What is the chemical formula for chromium sulfate? Problem 54 Name each ionic compound. Compounds are defined as substances containing two or more different chemical elements. Aluminum Oxide. Volatile (c) Conduct electricity in the molten state or in an aqueous solution but do not conduct electricity in the solid state Binary ionic compounds are composed of two atomic elements, held together with an ionic bond. Interestingly, all of the compounds in your list have bonds with greater covalent character, than ionic character. Covalent compounds Ionic compounds (composed of simple molecules) (a) Have high melting and boiling points (a) Have low melting and boiling points (b) Exist as solids at room temperature. 6) Carbon disulphide, covalent. Is it normal to have the medicine come out your nose after a tonsillectomy? Is HCl molecular or ionic? ... Cr2S3. For each of the following compounds, state whether it is ionic or covalent, and if it is ionic, write the symbols for the ions involved: (a) $\mathrm{KClO}_{4}$ ... Name each ionic compound. That is kind of irrelevant. Classify the compound copper(I) chromate as ionic or covalent. The resulting compound carries a neutral electrical charge. That is kind of irrelevant. It is a chemical bond between two different atoms (one metallic and another nonmetallic) in which an atom yields one electron to another (there is a transfer). Chromium(III) sulfide < 3. Chromium sulfide (Cr2S3) Chromium(III) sulfide.
