Aaron Wong History and Development of the Periodic Table Period 11 The most basic arrangement of the periodic table was in 1649. By this time, many elements have been known but the first scientific discovery of an element was in 1649. Hennig Brand discovered phosphorus, …
Fermentation is anaerobic respiration whereby food is altered into more simple compounds and energy in the form of chemicals is produced, an example being adenosine triphosphate (biology-online. org/dictionary/Fermentation). All this occurs with the lack of atmospheric oxygen. At the end of the day alcohol and …
Flame Test Lab Question: When a compound is placed in the flame of a burner, what happens to the color of the flame? Hypothesis: When the compound is placed in the flame, the flame changes color depending on the chemical compound. When they’re heated, they …

INTRODUCTION: WHAT IS HARDNESS OF WATER: It is when water passes through or over deposit such as limestone; the level of Ca²⁻and Mg²⁺and HCO₃ ions present in the water can greatly increase and cause the water to be classified as hard water. This term results …
The periodic table has been updated all throughout history. Elements have been around us since the beginning of time. Elements, such as gold and silver, are examples of these elements that have been known for centuries. The periodic table allows us to see the elements …
Origin of name: from the Latin word “Rubidius” meaning “dark red” or “deepest red”. Properties: Rubidium may be liquid at room temperature. It ignites spontaneously in air and reacts violently in water, setting fire to the liberated hydrogen. Thus, rubidium must be stored under dry …

An Enterotube II is a miniaturized multi-test system …
Experiment. EDTA Titration of Ca2+ in an unknown solution Experiment. EDTA Titration of Ca2+ in an unknown water sample Modified 9/2012 Objective: The most common multivalent metal ions in natural waters are Ca2+ and Mg2+. In this experiment, you will find the total concentration of …
Medium formulation is an essential stage in the design of fermentation process. Most fermentation media require liquid media, although some solid-substrate fermentations are also operated. Fermentation media must satisfy all the nutritional requirements of the microorganisms and fulfill the technical objectives of the process. There …
91 Chapter 5 Sources of plant nutrients and soil amendments A large number of diverse materials can serve as sources of plant nutrients. These can be natural, synthetic, recycled wastes or a range of biological products including microbial inoculants. Except for microbial inoculants (biofertilizers), all …
All cells need to have a constant energy supply. The two processes by which this energy is attained from photosynthetic materials to form ATP are cellular respiration and fermentation. (Hyde,2012). Fermentation is a way of harvesting chemical energy that does not require oxygen. (Reece et …

Interdependence In Nature Many of the relationships between organisms in nature are those of dependence. Whether it be a deer breathing oxygen produced by a nearby tree or a tick sucking the blood of its unsuspecting host, every organism depends on another organism in some …
Conjugation
The word "conjugation" is derived from a Latin word that means "to link together". In organic chemistry terms, it is used to describe the situation that occurs when π systems (e.g. double bonds) are "linked together". An "isolated" π (pi) system exists only between a single pair of adjacent atoms (e.g. C=C)
Kinetic energy
Kinetic energy is the energy associated with objects in motion. Potential energy is the type of energy associated with an object's potential to do work. Chemical energy is the type of energy released from the breakdown of chemical bonds and can be harnessed for metabolic processes.
Physics
Chemical physics is concerned with the application of the concepts and theories of physics to the analysis of chemical systems and their physical behaviour. While also at the interface between physics and chemistry, it is distinct from physical chemistry.
