Do you know what Potassium cyanide is‚ what it does to your body‚ and what its use is? This paper will answer all those questions‚ and will specifically examine how potassium cyanide affects the body and how it is used. Potassium cyanide is a white crystalline salt solid that has a faint‚ bitter-almond like smell. It’s empirical formula is KCN. The taste of KCN is described as burning the tongue and tasting acrid. This compound deliquescent‚which means that it tends to dissolve. The appearance is

Cathode negative electrode connected to negative terminal of d.c. source. Reduction occurs here. Cathode gains negative charge as electrons flow from the battery towards the cathode‚ making cathode negatively charged. This causes cation to be attracted and gains electrons to be an atom. Anion

Experiment 42: Ferrocene Preparation Introduction: The purpose of the lab is to prepare ferrocene from ferrous chloride and cyclopentadiene. Ferrocene‚ an organometallic‚ is a combination of two cyclopentadienide ions with a ferrous cation‚ such that the six pi electrons binds every carbon equally to the metal forming a sandwich type structure. Ferrocene has the properties of both an activated benzene (undergoes electrophilic substitution reactions) and a ferrous ion (oxidation reaction). Glyme

Assessment 1) Describe the difference between ionic and covalent bond. Ionic bonds have electrostatic forces that hold cations and anions together‚ and are electronic neutral. Covalent bonds are bonds that don’t give or take any electrons. In stead they share the elctrons 50) Which of these compounds contain elements that do not follow the octet rule? Explain. a) NF3: 5 + (7*3) = 26 b) PCl2F3: 5 + (7*2) + (7*3) = 40 c) SF4: 6 + (7 *4) = 24 d) SCl2: 6 + (7*2) = 20 The answer is “d”

Brayden Shaver Electrolytes in Sports Drinks September 30‚ 2016 Electrolytes in Sports Drinks Drinks are full of many substances that make up the taste‚ color‚ and uses of the beverages. One very important part of a sports drink are electrolytes. An electrolyte is a liquid gel that contains ions and can be decomposed by electrolysis‚ it is present in a battery. This substance is in many of the everyday drinks we use. From the orange juice we drink in the morning to the many sports drinks

form a chemical bond because these atoms already have a full outer shell of energy. Ionization: the process of gaining or losing electrons to become an ion. -ion: atom that has a net positive or negative charge. -anion (negative ion): an ion with a negative charge. -cation (positive ion): an ion with a positive charge. Oxidation number: number of electrons an atom gains‚ loses‚ or shares when it forms a chemical bond. -remember this pattern: +1‚ +2‚ +3‚ +/-4‚ -3‚ -2‚ -1‚ 0 -example:

Hydroxide ion binds to the copper (II). This is an example of metathesis as the cations and anions exchange partners. Reaction Three‚ Heating the copper hydroxide to a medium boil on the hotplate while occasionally stirring produces copper oxide. Heating allows for decomposition. It also allows the copper to oxidize. 50 mL of hot water was
