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

BIOPOL Biopol is a biopolymer that is an environmentally friendly biodegradable plastic made from renewable resources (made naturally in plants from starch and glucose). Biopol 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.

Arenes The aromatic hydrocarbons also have the name arenes. They contain in their molecule one or more cycles made up from 6 carbon atoms. When the molecule is formed out of a single cycle‚ the hydrocarbons are mono nucleuses; when the molecule contains more than one cycle‚ the hydrocarbons are poly nucleuses. The simplest aromatic hydrocarbon‚ benzene‚ is compound out of just one such cycle; its formula is C6H6. The representation of benzene through a cycle of 6 carbon atoms with 3 double bounds

Introduction Silver is a chemical element with atomic number 47 and symbol Ag. It is white‚ soft‚ mallable and ductile metal slightly harder than gold. Silver is extremely flexible‚ this means that it can be converted into both flat sheets and electrical wire. This makes silver is an ideal metal for all kinds of industrial use. Silver occurs in lead‚ Zinc and copper ore deposits. Lead ore is the main source of Silver. In fact‚ 75% of the resources in the world are found in association with other

Then you drop the Alka-Seltzer in the water and time how long it takes it to dissolve in the water. 3. Then we need to make the temperature go up then we need to drop the Alka-Seltzer in the water again and see how long it takes it to dissolve with the new temperature. 4. Now
