Lost and Found It’s a story that many people have lived through‚ from one side or the other. You’re a child in a busy department store‚ tethered to your mother’s side by her firm grip on your hand‚ your eyes constantly drawn left and right by the colorful displays. She lets go to grab something or talk to a salesperson‚ and you see an exciting toy or stuffed animal and run to it.

“Lost and Found” “To live is to experience tragedy” is what I learned from elders coming up as a child. Whether it befalls one individually or simply those around‚ tragedies are a part of life. Sometimes tragedy happens for no apparent reason it could be in the wrong place at the wrong time or just accidental. Tragedy without any explanation is a mournful experience. For others‚ tragedy is a consequence of choices an individual makes. This brings me to my point or experience that has changed my

2. An aqueous solution of KCl is colorless‚ KMnO4 is purple‚ and K2Cr2O7 is orange. What color would you expect of an aqueous solution of Na2Cr2O7? Explain. Orange. 3. Explain why hexane will dissolve benzene but will not dissolve sodium chloride. Sodium chloride is an ionic compound. 4. Some drinks like tea are consumed hot or cold‚ whereas others like Coca-Cola are consumed only cold. Why? For taste reasons‚ these drinks can be drunk if the user likes It but having coca cola like tea

Similar to potassium‚ sodium is a major mineral‚ however‚ unlike potassium which maintains fluid and electrolyte balance inside the cell‚ sodium is a major part of the body’s fluid and electrolyte balance system because it is the chief ion used to maintain the volume of fluid outside cells. Sodium also helps maintain acid-base balance and is essential to muscle contraction and nerve transmission. The DRI recommended intakes for sodium for adults ages 19 to 50 years old is 1‚500 milligrams per day

In the experiment‚ we tested a sodium chloride solution. Along with the tested solution‚ control groups (water and sodium phosphate) were used to be help understand whether or not NaCl was a buffer. Water was the negative control group and sodium phosphate was the positive control group. If NaCl was a buffer than the pH would be stabled as the sodium phosphate buffer. If NaCl was not a buffer than the pH would fluctuate like the negative control‚ water. During the first trial and prior to the drops

Making Sodium Chloride Equipment: Method: 1. Firstly‚ safety measures were taken by putting on laboratory coats‚ wearing safety goggles and tying long hair back. This was to protect clothing‚ eyes and to avoid burning as the experiment included dealing with open flames. 2. The equipment needed (as shown and labelled in picture A) was collected. 3. Using a measuring cylinder for each‚ to be exact with measurements‚ we measured out 10cm³ of HCl and 10cm³

INTRODUCTION Sodium hypochlorite is considered one of the most efficient irrigant in endodontics 1-4. Due to its antimicrobial‚ tissue dissolving properties and low cost‚ it is one of the most widely accepted irrigant in Endodontic practice 5-8. Sodium hypochlorite as a solution is relatively an unstable compound. On exposure to organic compounds‚ heat‚ light‚ air and metals‚ the available chlorine ions reduce and there is subsequent loss of tissue dissolving and antimicrobial properties 9-10. Recent
