Water Pollution
Water constitutes nearly three-fourths of the Earth's surface and it composes a large proportion of all living plant and animal matter. Approximately 70% of human body is water. Man drinks about 2 liters of water daily and it is required in abundance for dome..
Molecule of Oxygen (O = 8)
An example of sharing of two pairs of electrons (Double bond). Two atoms of oxygen share two pairs of electrons to form one molecule of oxygen (Fig. 3.5). Note :..

Tracheids are elongated dead cells that have sloping end walls. The cavity is empty as the cells are dead. The walls are thickened with a material called lignin. These thickenings are in different patterns. The cells are arranged end to end. Vessels are also dead cells that have variously patt..Oxygen Molecule (O2)
Therefore, oxygen molecule has 16 electrons. In the formation of molecular orbitals, the electrons in the inner shells are expressed as KK denoting ( s 1s) 2 ( s *1s) 2 .The remaining 12 electrons are filled in molecular orbitals. fig 1.20 - Molecu..

Water is a unique and remarkable compound, essential to all forms of life. Human beings and the flora and fauna cannot survive without water on this planet. A large amount of life on this planet is aquatic based i.e., can only survive in water. It is the most abundant..

. Its sources are sewage that includes organic matter, industries, agricultural chemicals, oil spill, etc. The major pollutants are the organic matter of the sewer, metallic substances and other inorgaic chemicals from the industries, hot water, oil, inorganic fertilizers and pe..
Increasing and Decreasing Functions
This section explains how derivative can be used to check whether a function is increasing, decreasing or neither increasing nor decreasing in its domain. Let f be a function defined on an interval I and let x 1 and x 2 be any two points on I. (i) f..

Soda glass, also called window glass, is got by fusing sodium carbonate (Na 2 CO 3 ), calcium carbonate (CaCO 3 ) and sand or quartz (SiO 2 ) in proper proportions. Small amount of scrap glass (pieces and bits of waste glass from previous process runs) is added as a fl..

Each oxygen atom has six electrons in its valence shell. Thus, it requires 2 more electrons to achieve the nearest noble gas configuration. This is achieved by sharing two pairs of electrons by the two oxygen atoms as shown below: ..

Pollution of the atmosphere with industrial gases has been found to result in as much as 15% loss. Soot can block stomata and reduce the transparency of the leaves. Some of the other pollutants are ozone and sulphur dioxide. In fact, lichens are very sensitive to sulphur dioxid..

They made my daughter to quiz herself with flashcards. The strategies that taught,helped her to learn the mulitiplication facts more easily- Slavic
Really helpful and explained things very clearly! Even though my session got over I can complete my homework myself
Turtors are so good, and patient and most important knows their stuff. They really tutor in a very professional way. Their system is unique and they really knows how to explain and made sure you undertand. They even put stuff from a book into the white board, just to show me how the process of my question - Paul
The tutor made sure i was learning and made sure i was paying attention, superbbbb session. Thank u
