Pin on Chemistry Worksheets and Handouts. … Do not proceed to schedule a custom demo unless you have already conferred with the lecture demonstrator about it. Use different tweezers for each substance to avoid contamination. Try: calcium phosphate carbon dioxide. Lab 4.docx - Answer these questions before beginning the lab ... Chemical Reactions - Experiment. This demo illustrates these rules. The university expressly disclaims all warranties, including the warranties of merchantability, fitness for a particular purpose and non-infringement. If given the name, provide the formula. Potassium Iodide and Lead (II) Nitrate Observations: Molecular Total Ionic. In the net ionic equation, any ions that do not participate in the reaction (called spectator ions) are excluded. 3. sulfur dioxide. Plumbum jodatum. while the demo proceeds. Calcium hydroxide--ionic, but the hydroxide ion has a covalent bond in it. Solved: I. (Honors Chemistry) Write which type of compound it is, whether the compound is ionic, molecular, or an acid. Question: Is H2SO3 an ionic or  Molecular bond  ? Metal + Nonmetal = ionic Nonmetal + Nonmetal = molecular. Lead (II) sulfate tricarbon octaiodide . Handle them with care. The product is the ionic compound, sodium chloride. c) net ionic equation. The solubility rules tell us that salts of group 1 (IA) metals are soluble, salts containing the nitrate anion are soluble, and salts containing the iodide anion are insoluble except for those containing the lead(II) cation (among others). Suggestion: have students:  a. predict the products from the Solubility Rules, b. write the molecular equation, c. write the full ionic equation, d. write the net ionic equation, and e. draw particle diagrams. At least include the state symbols in the balanced equation: Pb(C2H3O2)2(aq) + 2NaI(aq) --> PbI2(s) + 2NaC2H3O2(aq) The reaction produces insoluble lead (II) iodide. Molecules can be ionic OR covalent, but not both. Suggestion: have students: a. predict the products from the Solubility Rules, b. write the molecular equation, c. write the full ionic equation, d. write the net ionic equation, and e. draw particle diagrams. The net ionic reaction is Pb2+(aq) + 2 I-(aq) --> PbI2(s), The Kspof PbI2 is 9.8 X10-9. An ionic compound is composed of ions that may have a positive or negative charge. Question =  Is ClF polar or  nonpolar ? Lead(II) iodide. The university shall not be liable for any special, direct, indirect, incidental, or consequential damages of any kind whatsoever (including, without limitation, attorney's fees) in any way due to, resulting from, or arising in connection with the use of or inability to use the web site or the content. PbSO4 C3I8. PbI2 (lead iodine), however, is ionic. Answer =  CF2Cl2  (Dichlorodifluoromethane)  is  Polar What is polar and non-polar? Those that come with opposite charge can be held together strongly within the compound. CTK0F6521. The line of precipitate does not begin to appear until a two or three minutes time have elapsed and it takes a few more minutes for the line to reach across the dish. ... Precipitation of Lead(II) Iodide | Chemdemos. © Copyright 2012 Email: If no reaction occurs, write NO REACTION. Question =  Is CF2Cl2 polar or  nonpolar ? ____1. However, if the camera is of low quality students may not see the vivid yellow color of the precipitate. 2. carbon monoxide. Can you name binary ionic and molecular compounds? This demonstration provides evidence to support this claim. Zinc chloride reacts with lead nitrate to form zinc nitrate and lead chloride. Question =  Is CLO3- polar or  nonpolar  ? Answer =  AsH3  ( Arsine )  is  Polar What is polar and non-polar? When these two solutions are mixed, the lead(II) cations, #"Pb"^(2+)#, and the iodide anions, #"I"^(-)#, will bind to each other and form lead(II) iodide, an insoluble ionic compound. Binary ionic compounds typically consist of a metal and a nonmetal. Question =  Is SCN- polar or  nonpolar ? Answer =  ClF  (Chlorine monofluoride)  is  Polar What is polar and non-polar? Presenting the Demonstration   This demonstration takes about 8 minutes to perform if you rush through it and do it is as a teacher presenting information to students. There is no standard term for this type of equation. Randy Sullivan, University of Oregon The ionic equations are; ZnCl 2----- > Zn +2 + 2Cl-1 Pb(NO 3) 2----- > Pb +2 + 2NO 3-1 The net ionic equation for the reaction is; At room temperature, it is a bright yellow odorless crystalline solid, that becomes orange and red when heated. Question =  Is ICl3 polar or  nonpolar  ? Cr 2O3 chromium (III) oxide NaBr sodium bromide PbI 2 lead (II) iodide HCl hydrogen chloride Al 2O3 aluminum oxide BN boron nitride RbI rubidium iodide BaF 2 barium fluoride On an overhead projector sides of the Nonmetal with its ending changed to – ide II nitrate solution sodium...
