Chemical bond Essay
Answer the pursuance questions in your own words, using complete sentences. Based on your observations in the lab, categorize each unidentified compound as noodle or covalent. Explain in one or two sentences why you categorised the compounds the way that you did. (5 points)Based on my observations in the lab I categorized Substance A and Substance C as an ionic bonds because the solids bustt conduct electricity but when in liquid subject and aqueous solutions, electricity was conducted. I categorizedsubstances B and D as covalent bonds because the solids conduct electricity but the liquid pronounce and aqueous solution do not.Explain, in your own words, the differences between ionic and covalent bonding that account for the differences in their melting points. (4 points) Ionic bonds typically suck much higher melting points than covalent bonds because of their crystal-like structures. The bondage is much much complex and requires higher heat to break than a covalent whose bo nds argon broken relatively easy.In order to conduct an electrical current, a substance must have charged particles (ions or electrons) that argon free-moving (able to crusade about throughout the sample).Why do you gestate ionic compounds be not able to conduct electricity as solids, even though they can as liquids and in solution? (2 points) I think ionic compounds cant conduct electricity as solids because the particle are all packed together and have no room to live on freely as opposed to the particle when in liquid state or solutions.Based on your research and observations, why do you think pure (distilled) water does not conduct electricity but tip off water usually does? (2 points)I think this is because tap water contains more(prenominal) ions than distilled water allowing it to conduct electricity. I also think the minerals that dissolve in the water have a lot to do with the conductivity.
