WebNitrogen oxide reacts with hydrogen at elevated temperatures according to the following chemical equation: 2NO (g)+2H2 (g)→N2 (g)+2H2O (g) 2NO(g)+2H 2(g)→N 2(g)+2H 2O(g) It is observed that, when the concentration of H2 is … WebWhile passing through renal tubules, water and a lot of other substances are reabsorbed making filtrate concentrated. This also gradually results in an increase in the concentration of urea as it is not reabsorbed like water or glucose. Some substances like K+, H+ are also secreted (not urine). WebThe solution was then filtered to remove the catalyst by passing through a bed of Celite, and the bed was washed with dichloromethane. The filtrate was concentrated under reduced pressure to viscous oil, and hexane was added to give a yellowish-white precipitate of the diamine (yield: 0.8 g [96%], mp 196°C–198°C). hiirenkarkotin sisälle

WebStimulation of osmoreceptors can lead to secretion of the hormone ADH. Describe and explain how the secretion of ADH affects urine produced by the kidneys (4) A. - Water potential of blood will decrease; - Water moves from osmoreceptor into blood by osmosis. - Permeability of cells (to water) is increased;

WebSo, the glomerular filtrate concentrates as it moves down through the descending limb. Reabsorption is minimum in the ascending limb. This limb is impermeable to water but electrolytes can be transported actively or passively. So, as the concentrated filtrate moves upward it gets diluted due to the passage of electrolytes to the medullary fluid. Web1 dag geleden · Urine contains water, urea and salts.
