ANSWER

Ammonia is present in small quantities in air and soil where it is formed by the decay of nitrogenous organic matter e.g., urea. On a large scale, ammonia is manufactured by Haber’s process. In accordance with Le Chatelier’s principle, high pressure would favour the formation of ammonia. Ammonia is a colourless gas with a pungent odour. Its freezing and boiling points are 198.4 and 239.7 K respectively. In the solid and liquid states, it is associated through hydrogen bonds as in the case of water and that accounts for its higher melting and boiling points than expected on the basis of its molecular mass. Ammonia gas is highly soluble in water. Its aqueous solution is weakly basic due to the formation of OH– ions. The presence of a lone pair of electrons on the nitrogen atom of the ammonia molecule makes it a Lewis base

Why sino atrial node is called pacemaker

Posted by Amit Kumar 1 year, 3 months ago

CBSE > Class 12 > Biology

Anushka Singh 1 year, 1 month ago

The sino-atrial (SA) node is a specialized bundle of neurons located in the upper part of the right atrium of the heart. The cardiac impulse originating from the SA node triggers a sequence of electrical events in the heart, thereby controlling the sequence of muscle contraction that pumps blood out of the heart. Since the SA node initiates and maintains the rhythmicity of the heart, it is known as the natural pacemaker of the human body.

Sewage mainly includes human excreta and contains large amounts of organic waste and pathogenic microbes. Thus it is necessary that waste should be made less polluted before discharging into water bodies. The process of sewage treatment is explained in the following steps: a) Primary treatment - In this treatment, filtration and sedimentation process is applied to remove large and small particles. Filtration process removes the floating debris by passing it through mesh wire screens. Then sedimentation removes the soil and small pebbles. The sediment is known as primary sludge and the supernatant is known as primary effluent. The effluent then enters the secondary treatment. b) Secondary treatment - In this treatment, large aeration tanks containing primary effluent are constantly agitated with a continuous supply of air. Thus aerobic microbes grow vigorously consuming a major part of the organic effluent reducing biological oxygen demand (BOD) of the effluent. The sewage is then passed into the settling tank where bacterial flocs settle and now it is known as activated sludge. Some of the activated sludge is again passed into aeration tank to serve as inoculum while rest of it enters into large tanks called anaerobic sludge digesters. Here anaerobic bacteria grow to produce a mixture of gases such as methane, hydrogen sulphide and carbon dioxide to form biogas. This effluent can then be released into natural water bodies
