. In normal respiration, the haemoglobin of blood gets oxidises to an unstable compound, oxy-haemoglobin. This compound serves as an oxygen carrier. It carries the oxygen to the cells and in the process it is reconverted into haemoglobin. It returns to the lungs to repeat the process. Carbon..

It has strong affinity to combine/bind with haemoglobin in blood to form carboxyhaemoglobin, which reduces oxygen carrying capacity of blood to cause headache,nausea ,asphyxiation and fainting (low supply of O 2 to body though one may inhale normally). Against normal level of 0.5% CO in b..

Tests for Carbon Monoxide - 1. Carbon monoxide is colourless, neutral gas. 2. It burns in air or oxygen with a pale blue flame to form carbon dioxide. 3. Carbon monoxide has no action on limewater, whereas carbon..

1. Carbon monoxide is used as a fuel by itself, or in the form of producer gas (mixture of carbon monoxide and nitrogen), or water gas (mixture of carbon monoxide and hydrogen). It is also present in fuel gases like coal gas. 2. ..

You may have observed that, when coal, coke or charcoal is burning, a pale blue flame is visible (Fig.11.1). The blue flame is actually due to the burning of carbon monoxide. When the supply of oxygen is in plenty, carbon initially burns to form ..

A simple D.C. generator consists of a rectangular coil ABCD which can be rotated rapidly between the poles N and S of a strong horse-shoe type magnet M. The generator coil is made of a large number of turns of insulated copper wire. The two ends of the coil are connected to the two copper half ring..

It consists of N turns of coil PQRS wound over a non-magnetic metallic frame usually rectangular or circular. The coil is suspended from a torsion head H by means of phosphor bronze strip in a magnetic pole by pieces N and S. A mirror M is attached to the phosphor bronze strip. The other end of th..

This laser consists of a discharge tube in the cylindrical shape containing helium Neon gas in the ratio 9:1 at a low pressure. Two mirrors M 1 and M 2 are placed at the ends to facilitate the longer availability of emitted photons. A large potential difference is applied bet..

'S' is a large spherical conducting shell of radius few meters. C 1 and C 2 are the two supporting pillars. An insulating material like silk acts like a conveyor belt wound over two pulleys P 1 and P 2 . The pulleys move with the help of a motor. B 1 and B 2 are ..

Through A, B and C draw lines parallel to BC, AB and AC respectively. Let these lines meet at P, Q and R forming D PQ..
