Question 1

Soil is divided into three major soil phases. The three soil phases are; complex, association and undifferentiated groups. Each soil phases has unique chemical and physical properties that learners and surveyors use to distinguish one soil phase from the other. The common physical properties that are used to distinguish the three soil phases are: depth, clay, moist bulk density, available water capacity and organic matter content. On the other had the chemical properties that are used to distinguish the soil phases are cation exchange capacity and pH. The table below shows the chemical and physical properties of the three ...

Explain Hardness of Water

Explain Hardness of Water
The water that occurs in nature always contains salts, which exist in water as positive and negative ions. The salinity of fresh water is 1000 mg/L (1L of water contains 1000 mg of various salts or ions). The typical cations present in natural water are sodium, potassium, calcium and magnesium; the most common anions are chloride, sulfate, bicarbonate, nitrates, etc. Hardness of water refers to presence of calcium and magnesium ions. When water is heated, the reaction (Tebbutt, 1999):

takes place. Calcium carbonate, unlikely other salts, is insoluble and forms precipitate. The precipitate is ...

Abstract

Adsorption differs from absorption and activated clays are one of the most effective adsorbents in nature. The adsorbing action of activated clay is a selective adsorption process. Due to its effectiveness, activated clay has wide applications such as cleaning up oil spills and adsorbing dyes. Zeolite made up of silicon, aluminum and oxygen is also an adsorber, and it can be synthesized. Synthesis simply increases its pore or cavity sizes and makes it hydrophobic. Zeolites are selective adsorbers because of their unique pore sizes. Zeolites are used in removing heavy metals such as zinc, iron, copper, chromium and so ...

Some people choose to act violently as a way of releasing feelings of frustration, desperation or anger. As such, they undermine the use of nonviolent means of dealing with their negative feelings. Violent tendencies in the United States is a profound issue among the young people. However, there is no general explanation for the increase in youth violence over the years. Several things may be responsible for violent behavior among the American youth including peer pressure, low self-esteem, low educational achievement, witnessing domestic violence, being victims of early childhood abuse among other factors that may trigger negative emotions. Youth violence has ...

Chapter 3 Atoms and the Periodic Table

For centuries, many have tried to learn about the smallest particle. As far as 2500 years ago, Democritus and Leucippus created an idea for the atom and called it ‘atmos’ meaning indivisible. Various philosophers and scientists have proposed models for what and how the atom should be. The initial theory proposed by Dalton in 1803 states that atoms are indivisible and that all atoms of a particular material are identical. He also stated that atoms of different materials join to form compounds. J.J. Thompson proposed the initial model of the atom. It is called the plum pudding model. He theorized ...

Introduction

In the recent past, studies in the field of cognitive science have brought forth overwhelming evidence on the relationship between moral judgment and emotions. However, research on this topic a couple of decades old. For instance,StanleyMilgram, a social psychologist, carried a research on this topic in the 1970 where he instructed his students to approach strangers in New York subway and request for a sit. The research did not receive the kind of reception Milgram expected, he noticed that most of the students declined to participate. However, one student who offered to do the research aborted it prematurely. Left with no alternatives, ...

Positron Emission Tomography (PET) is a method of medical imaging that works by detecting gamma rays produced by the interaction of electrons with positrons after a tracer radionuclide is injected into the body. The tracer radionucleotide used is dependent on the part of the body that is being investigated, in some cases it is modified glucose, in others, it is a receptor ligand. Common uses of PET scans are cardiac studies that measure the oxygenation of the tissues of the heart and the function of the heart muscle, to detect skeletal trauma and bone cancers, kidney imaging to study the renal function ...
