CHEM111AC‚ Experiment#9 - Ionic Reactions Discussion/Error Analysis In the first part of this experiment‚ the student was presented with 7 unique and unidentified bottles of solutions labeled A-G and was expected to be able to analyze the 7 solutions through trial and error and mixing them with one another. For solution A: mixing A + B formed a precipitate‚ A + C generated heat‚ A + D gave no reaction‚ A + E gave no reaction‚ A + F gave no reaction‚ A + G formed a precipitate. For solution B: mixing

Columns had ornamental capitals—the top of the column—in one of three designs. The simplest‚ Doric‚ consisted of columns with plain molded capitals and no base. Ionic capitals were decorated with a pair of scrolls‚ known as volutes. Corinthian capitals‚ the most ornate‚ were decorated with an inverted bell-shaped arrangement of leaves. Prime examples include the Parthenon and Erectheum‚ in Athens. From 100 B.C. to A.D. 365‚ the Romans‚ like the Greeks‚ built many magnificent buildings‚ including temples

a much more polar molecule than 2-propanol. How does the polarity of the liquid seem to influence the solubility of these solids? Water is more of a polar molecule then the given 2-propanol which allows ionic soild‚ sodium chloride that breaks off and becomes soluble. Camphor is not an ionic solid which means that it is not soluble in water although of the given molecular polarity. 9. What does a strong odour indicate about the ease with which the particles in a solid leave its surface? A

possible. 1. Describe metallic‚ ionic and covalent bonds. Metallic - A chemical bond in which electrons are shared over many nuclei and electronic conduction occurs. Ionic – A chemical bond in which one atom loses an electron to form a positive ion and the other atom gains an electron to form a negative ion. Covalent - A chemical bond that involves sharing a pair of electrons between atoms in a molecule. 2. Explain the structure of metals‚ ionic compounds‚ covalent molecules and covalent

and Net Ionic Equation Going back to our first concept or topic‚ we’ve learn how to identify the Oxidizing and Reducing agent and the Oxidation as well as the Reduction. In this part of the Redox reaction or in this step‚ it is very important that you already know the Oxidizing and Reducing agent for us to find the half reaction. In this step or part‚ we will also learn how to balance using the addition of electrons in both sides if necessary. After this step we can now write the net ionic equation
