Chemistry 2202 Review Final Exam Chapter 2: The Mole 1. Isotope – atoms of an element that have the same number of protons but different numbers of neutrons. Ex. The three forms of oxygen are called oxygen-16‚ oxygen-17‚ and oxygen-18. They all have 8 electrons and are written as 16/8 O (8 protons + 8 neutrons)‚ 17/8 O (8 protons + 9 neutrons)‚ and 18/8 O (8 protons + 10 neutrons). 2. 3. Mass Number – the sum of the protons and neutrons in the nucleus of one atom of a particular

is the brand name for a group of biopolymers often called PHAs or PHBs. The continual use of petroleum to make polymers for plastic will eventually run out and hence Biopol was introduced as a polymer replacement for petroleum. It is made from an organic substance known as Alcaligenes eutrophus which is a microorganism. Biopol is stable when stored in air and even humid conditions. When the polymer is exposed to microorganisms found in soil‚ sewage‚ river bottoms or other similar environments‚ the

“depository” in Freire’s Banking Concept of Education‚ but no experience is more relative than my Organic Chemistry class three years ago where I learned that problem-solving education is vastly superior to banking-education because it allows students to acquire true understanding of their world and the ability to reach consciousness. During the summer of 2009‚ I took a summer semester of Organic Chemistry at University of California Berkeley. When I first entered the lecture hall‚ there were masses

VI. Results and Discussion In this exercise‚ the goal was to produce acetylsalicylic acid through the organic synthesis from the reaction of salicylic acid to acetic anhydride‚ the starting materials. Instead of using acetic acid‚ acetic anhydride was used as solvent since the anhydride reacting with water to form acetic acid tends to drive the reaction to the right. It results from the elimination of a molecule of water from two molecules of acetic acid (see Fig. 11.2). Figure 11.3 below

A student was assigned a certain task by his teacher in chemistry lab. During the experiment‚ student dropped the flask containing 250 ml‚ 3 molar NaOH solution. Due to this 50 ml of solution out of 250 ml‚ had fallen on the floor. Thinking that teacher may punish him for this mistake‚ he replenished the left over solution with 50 ml of water. The new molarity of NaOH solution will be. (A) 2M (B) 3M (C) 2.5 M (D) 2.4 M 2.* Which of the following molarity values of ions in a aqueous solution
