Explain the type of the reaction and positiveΔSrxn?A(s)+B(s)→C(g). Combination Reaction: There is the formation of only a single product by using two or more than two molecules or atoms or reactants in this type of reaction. Generally, these reactions are of exot...
Across the stable density stratification of the abyssal ocean, deep dense water is slowly propelled upward by sustained, though irregular, turbulent mixing. The resulting mean upwelling determines large-scale oceanic circulation properties like heat and
What is the standard enthalpy of formation? Explain it with example. 03:18 Define and explain the enthalpy of combustion (Delta(c)H^(theta)). 02:36 Define and explain the bond enthalpy (Delta("bond")H^(theta)). 05:08 What is the bond enthalpy of C-H bond of CH(4)? 02:33 Defi...
Beyond identifying factors influencing roost site selection, the large aggregations of individuals in single locations may suggest that presence of conspecifics itself also plays a role in the formation of Whimbrel roosts. We highlight the interaction of food and risk landscapes with intraspecific ...
Although many different extensions and elaborations of these simple mechanisms are used to capture different nuances in participants’ behaviour, they all share a common approach, which is that decisions are made to maximise reward, and that the history of obtained rewards drives the formation of ...
Define the term activity series. What information does it provide? Describe how cyclotrons work. Explain: 2H2O + C \longrightarrow CO + 2H2 Zn + 2HCl r H2 + ZnCl2 Define and explain Hund's rule. Explain the origin of the bands in an IR spectrum. Briefly explain enolate formation. Exp...
The reaction of formation of a metal oxide from a metal is as follows : 2xM(s)+O(2)(g)rarr 2M(x)O(s) In this reaction, gaseous O(2) is used up to from solid metal oxide. Change of state from gas to solid indicates DeltaS is -ve. Hence, with rise in tem
Although the internal wave-driven mixing picture is known to break down in particular locations of the ocean, notably near the ocean's surface and bottom boundaries and in regions with strong currents, high mesoscale activity (where interactions between geostrophically balanced motions and internal ...
(De Ridder et al., 2014), entry of the tinnitus signal into wider perceptual networks (De Ridder et al., 2013), and a predictive coding model in which tinnitus perception is the interplay of spontaneous synchronous activity and the formation of concordant top-down sensory predictions (Sedley ...
Life in the clouds of Venus, if present in sufficiently high abundance, must be affecting the atmospheric chemistry. It has been proposed that abundant Venusian life could obtain energy from its environment using three possible sulfur energy-metabolisms.
