Elementary transformations are of the following three types: Interchange of any two rows (or columns) The multiplication of the elements of a row (or column) by a non-zero number. The addition to the elements of any row (or column) the corresponding elements of any other row (or ..

In this representation one views the carbon-carbon bond directly end-on and represents the two carbon atoms by a circle. Lines going to the center of the circle represent substituents on the front carbon, and lines going to the edge of the circle represent substituents on the rear carbon. The adva..

The intersection of the horizontal and vertical lines represents the chiral center (the chiral carbon). The horizontal lines indicate bonds directed towards the reader. The vertical lines indicate bonds directed away from the reader. By rotating through an angle of 180 o within the plan..

The intersection of the horizontal and vertical lines represents the chiral center (the chiral carbon..

Theorem : - In any triangle ABC, with sides a = BC, b = CA and c = BA, then prove that a = b cos C + c cos B, b = c cos A + a cos C, c = a cos B + b cos A Fig (i) Fig (ii) Fig (i..

In optical microscope, the ray of light can be bent by a lens system. By placing the object and the lens system in such a way, we control the direction of the ray to get a magnified image of the object. Since as 'electron' carriers charge it is possible to change the direction of a electron beam by..

1) Project Tiger 50 years ago, there were over 40,000 tigers in India. But poaching and destruction of habitat had reduced the number to just 1827 by 1972, making them an endangered species. To protect the tigers from extinction, the Government of India started "Project Tiger" ..

It is a comprehensive international effort started in 1990 by molecular biologists to map the entire human genome by determining the complete nucleotide sequence of DNA of each chromoso..

The C-C bond is viewed end on. A point represents the near carbon and three lines radiating from this point represent the bonds linking the three other groups attached to this carbon. A circle represents the other carbon atom that is far away and the three bonds attached to this carbon atom are re..

Nina is working on a project. She planned to spend 50 days on the project. After the project was completed, she figured out that she had taken 120% of the estimated time to complete the project. Find the number of days she spent on the project. => 1..
