hydrogen, helium, oxygen, calcium vapors, sodium and potassium (fig. 1). The planet probably receives hydrogen and helium from the sun, and metals evaporate from its surface. This thin layer can be called ‘atmosphere’ only with great stretch. The pressure on the planet's surface is 500 billion times lower than on the surface of the Earth (this is less than in modern vacuum facilities on Earth). The maximum surface surface temperature recorded by the sensors is +410 ° с. The average temperature of the night hemisphere is -162 ° C, and the daytime temperature is +347 ° C (this is sufficient to melt lead or tin). Temperature descents due to the change of stations caused by orbit elongation...

hydrogen unions and hydrocoloidal aggregates. According to other behaviors: hydrogels that produce conformational change depending on the external environment, that is, physiologically sensitive hydrogels (dependent on pH, temperature, ionic force and electromagnetic radiation).   Chemical structure As we have mentioned earlier, a hydrogel is a network formed by different polymorphic compounds that are very absorbent and that, when joining a solvent, produce a conformational change by which they become very flexible. In addition, when swelling, its volume is significantly increasing, but the shape is always maintained until it reaches a physicochemical balance. Until the moment in which the...

hydrogen ions when the pH of the blood lowers below the optimum value. In this context, we will discuss the intracellular and plasma buffer system and how it function. Bicarbonate buffer system is the predominant buffer system that operates in the blood plasma. In essence, this buffer tries to strike a balance involving bicarbonate ions, carbonic acid and the carbon dioxide that are present in the blood plasma and body tissues. Carbon dioxide produced by the body cells react with water to form a solution of lower pH that contains carbonic acid. This acidic solution is unstable and always dissociate to form hydrogen ions and bicarbonate ions (Varum et. al 2014). The bicarbonate buffer system...

Hydrogen Bonding-Water Drops on A Penny Results Trial 1 Trial 2 Trial 3 Trial 4 Average Tap water 33 39 36 42 37.5 On soap-washed penny 15 20 17 22 18.5 Calculations The calculations conducted in the laboratory were supposed to get the average of the four trials Average: (Trial 1 + Trial 2 +Trial 3 + Trial 4)/ 4 Untouched penny average: (33+39+36+42)/4= 37.5 Soaped penny: (15+20+17+22)/4= 18.5 Discussion From the results above, it is clear that the penny that was not soaped required many water droplets before they spilled, as compared to the washed-up penny that requires fewer water droplets before spilling. This phenomenon is attributed to the surface tension and cohesion water...

Hydrogen Carbonate reacting with Vinegar is increased, the amount of Carbon (IV) Oxide produced also increases. Reaction between Acetic acid (Vinegar) and Sodium Hydrogen Carbonate is a decomposition reaction where the Carbonate is broken down by the acid to yield a salt ,water and Carbon (IV)Oxide as shown in the equation below: 2838450723900023145757239000 C2H4O2 + NaHCO3 NaC2H3O2 + H2O + CO2 An experiment for the above reaction was carried out whereby 50mls of Acetic Acid reacted with 0.25g, 0.5g,0.75g,1g and 1.25g of the Carbonate respectively. A balloon was fixed...
