between binary acids and oxyacids in terms of their component elements and the systems used in naming them. b. Give three examples of each type of acid. - Binary acids contain H atoms (which are released as H+ when the acid is dissolved) and a simple anion such as Cl- or Br - or S2-‚ while oxyacids contain H atoms and an oxyanion such as SO42- or NO3-. Two examples of binary are hydrochloric and hydrofluoric acid‚ and two examples of oxyacid are sulfuric and nitric. 3. Identify and describe the characteristic

Construct word and balanced formulae equations of all chemical reactions as they are encountered in this module: NOTE: In chemistry‚ [x] means “concentration of x” in moles per litre (mol/L). EG: [H3O+] means “concentration of H3O+ ions” in mol/L. BASIC reactions to remember: Acid reactions: acid + base salt + water acid + metal salt + hydrogen gas acid + carbonate carbon dioxide gas + salt + water Formation of hydronium: H+ + H2O H3O+ Reactions of

Additional Aspects of Equilibrium Common Student Misconceptions • • • • • Students often believe that the pH at the equivalence point for any titration is 7.00. In terms of problem-solving skills‚ this is probably the most difficult chapter for most students. Students tend to find buffers particularly difficult to understand. Students often forget to consider volume changes that occur when two solutions

What is Chemistry? Chemistry is the study of matter and energy and the interactions between them. This is also the definition for physics‚ by the way. Chemistry and physics are specializations of physical science. Chemistry tends to focus on the properties of substances and the interactions between different types of matter‚ particularly reactions that involve electrons. Physics tends to focus more on the nuclear part of the atom‚ as well as the subatomic realm. Really‚ they are two sides of the

C H A P T E R 5 Basic Concepts from Organic Chemistry 5.1 | INTRODUCTION The fundamental information that environmental engineers and scientists need concerning organic chemistry differs considerably from that which the organic chemist requires. This difference is due to the fact that chemists are concerned principally with the synthesis of compounds‚ whereas environmental engineers and scientists are concerned‚ in the main‚ with how the organic compounds in liquid‚ solid‚ and gaseous wastes

A. Role of Chemistry in Society Applications of chemical science have contributed significantly to the advancement of human civilization (1‚ 2‚ 3). With a growing understanding and ability to manipulate chemical molecules‚ the post-World War II chemist was considered a societal problem solver. They synthesized crop-enhancing agricultural chemicals to ensure a constant and viable food supply. They played a significant role in the eradication of deadly diseases by developing life-saving pharmaceuticals

ALCHEMY TO CHEMISTRY Can we say that alchemy and chemistry are two different things? Actually no‚ we can’t. Alchemy is the pioneer of today’s modern chemistry. As the time passed alchemy has changed and developed to form Chemistry. Therefore we shouldn’t think that they are two different subjects. In this article‚ first of all you will learn how alchemy was found and evolved .After that how it transitioned from alchemy to chemistry and finally the similarities and differences between them.
