Abstract: The purpose of this experiment is to examine the properties of several gasses‚ which were the products of a reaction‚ and examine the way the gasses react under certain conditions. These conditions‚ such as introducing a flame to the gas as well as oxygen and CO2‚ caused other reactions to occur. Hypothesis: If the gasses are correctly synthesized then there will be a clear reaction with the introduction of the flame‚ O2‚ CO2‚ Air‚ limewater‚ and Bromthymol indicator. Procedures: Step 1. I

Unknown Ionic Compound ILI#3 Abstract: In this laboratory investigation‚ 8 solutions were combined with each other and an unknown liquid #1 in order to identify the ionic compound in the unknown solution. The students performed an experiment in which the reactions between each substance were compared to the unknown solution #1’s reactions and the color of each solution was compared to help find the unknown #1. The unknown ionic compound was identified to be Zinc Sulfate as the reactions between

chemicals to determine acidity or basicity. Other reactions can be observed as well when different chemicals are added to each other. Procedure This experiment involved placing drops of specified chemicals into a well on a 96well plate. Each well number was recorded along with question number and name of chemicals involved. Two drops of a chemical were placed in a well along with two drops of another chemical. Chemical reactions and color changes were recorded in Data Table 1.

Writing Half Reaction 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

molecule with a positive or a negative charge due to the loss or gain of one or more electrons. Ionic solids are salts (such as NaCl) that are held together by a strong force of attraction between ions of opposite charge. Molecules are the smallest physical units of an element or a (chemical) compound. Ionic solids are also known as salts because salts are ionic compounds that are formed from a reaction between an acid and a base. Hydrates are inorganic salts which contain specific numbers of

How do ionic bonds form? Transferring the electron forms an ionic bond. After transferring the electron‚ the two atoms become ion n will attract together because they have the opposite charges. Then an ionic bond is formed. How do covalent bonds form? A covalent bond is for sharing of electrons. I remember it like co-existing electrons to share (Eg H20). It is usually between two non-metals. Which compound‚ sugar or salt‚ is a better conductor of electricity? Explain your answer. Salt

Lab: Ionic and Covalent Bonds Objectives • Understand the differences between ionic and covalent bonds. • Connect ionic and covalent bonds with physical properties of matter. Introduction Sugar and salt look so similar that most people cannot tell them apart without tasting them. Chemically‚ white refined table sugar‚ sucrose‚ and salt are very different. An ionic bond between a positive sodium ion and a negative chloride ion creates a molecule of sodiumchloride (NaCl). Covalent bonds between

Observations of Chemical Changes Purpose/Hypothesis: To observe how acids react with bases and examine reactions of common household cleaners and the macroscopic changes these chemicals undergo. I expect for each solution to react differently when mixed with acids and bases. Procedure: I have a well-plate-96‚ a piece of white and black paper‚ and the chemicals from the Observation of Chemical Changes Experiment Bag. I used a different well for each combination of solutions. I placed two

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
