identifies that there was a chemical reaction taking place. AX + B → A + BX Zn + Ag(NO3) → Zn(NO3) + Ag copper – Cu silver nitrate – Ag(NO3) In well 4 there was a reaction between the solid copper pieces and the solution silver nitrate. The copper rusted and changed to a dusty black-grayish color. This change in color identifies that a chemical reaction just took place. AX + B → A + BX Cu + Ag(NO3) → Cu(NO3) + Ag (8 points) |Score

Edward Dickson CHE101 DS-01 Experiment Date 7/21/2013 Report Submitted 7/21/2013 Title: Experiment #8: Ionic Reactions Purpose: In this lab we will work with aqueous solutions of ionic substances and determine if they are soluble. If the solution appears milky than it is known as a precipitate reaction‚ meaning it is soluble‚ and that the ions separated and became surrounded by water. Precipitates in this experiment are electrically uncharged. To identify which compounds are

Identifying Ionic Compounds Written by Ashleigh Lara. In our experiment we were given 5 different cations who’s mixture of anions ranged from five to three different solutions. At every single station we were given the following materials a spot plate‚ a dropper‚ and the chemicals used to mix with our main substance. Each substance received 3 drops of the different chemicals which were able to give us an observation of what the compound was made into. Many of our experiments color‚ texture and solubility

system of food delivery uses a hub-and-spoke system of foot‚ bicycle‚ handcart‚ and trainbased transport linking local village kitchens to urban consumers in metropolitan Mumbai. For an up-front investment of roughly 5‚000 Rupees‚ a dabbawala can earn an average of 5‚000-6‚000 Rupees per month. Each dabbawala donates a portion of his earnings to their member association‚ which invests the funds in community projects and low-interest loans. Known for its ingenious use of simple symbols to coordinate

Abstract In this assignment‚ there is a case example of Solution-focused Practice with evidence based. There are three theories which are role‚ activity and continuity to support the practice. Introduction Solution-focused Practice is a relatively new therapy which is just turning into a well-developed counseling model within these 20 years but there do not have much information about working this therapy with the elderly. There are many literatures about SFT working on different services groups

Ionic bonding is known as a type of chemical bond where the valence electrons are lost from one atom and gained by another. This exchange results in a more from one atom and gained by another. When an atom gains or loses electrons while being bonded with another atom an ion is formed. This bond causes an atom to become either a positive or negative ion. Electrons have a negative charge‚ meaning that if an atom loses an electron‚ the amount of protons are greater than electrons. This makes the atom
