Ionic Reactions Introduction: Today we are going to observe the chemical changes when mixing two solutions. Some will change colors‚ produce gases proving if the solutions are soluble or insoluble. Materials and Methods: I first pulled out the small wells and place two drops of the Cobalt (II) Nitrate in seven of the wells. I then moved to the next row and placed two drops of Copper (II) Nitrate in the next row‚ into seven of the wells‚ and so on with the other three Nitrates. I then cut off

molecular or ionic and if they are acidic or basic. Hypothesis: If the compound is ionic‚ then it will be soluble because the energy given off water molecules compensates for the energy needed to break ionic bonds‚ also‚ if the compound is Ionic‚ it will be an electrolyte‚ because they mostly break up into ions when in water. If the compound is molecular‚ then it will be soluble‚ it cannot be an electrolyte‚ and it can be an acid or base‚ because molecular compounds are soluble in organic solutions such

PURPOSE: To see which solutions are soluble and which are not. We were able to see this by mixing certain solutions together and observing changes that occurred.

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

Ionic Reactions Abstract This experiment is designed to study the nature of ionic reactions‚ and write net ionic equations for precipitation reactions‚ as well as to identify spectator ions‚ perception reactions and solubility of different compounds. Experiment and Observations In this experiment I was using a 96-well plate to add two drops of the following solutions into seven wells in rows A through E: cobalt (II) nitrate‚ copper (II) nitrate‚ iron (III) nitrate‚ barium

Developing an online system requires a series of tests and revision to ensure that the system effectively works. To illustrate the development of the system‚ a simplified version of the spiral life-cycle model was used. The spiral model combines the iterative nature of rapid prototyping in which the researchers established an understanding of the system and its objectives as well as its functionality‚ ability to accommodate change‚ constraints‚ and other alternatives in achieving those objectives

the wooden originals. The temples had painted decorations and low-pitched wooden roofs. 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

How to Form Ionic Bonds 1. Explain (step-by-step) how to form ionic bonds between Li+ and N-3. First‚ understand that all atoms want full shells. All atoms‚ except for noble gases‚ have valence electrons. These electrons are the ones on the outermost shell. All atoms either want to get rid of these electrons or gain enough to make a full shell. Metals‚ which are on the right side of the periodic table‚ have less than 4 valence electrons. This means they want to get rid of those electrons. Nonmetals
