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 ...
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.
What is the specific heat capacity of a sample? Define the specific heat capacity of a substance. Given S O 2 S + O 2 , H = 300 k J 2 S O 2 + O 2 2 S O 3 , H = 200 K J , calculate the heat of formation of S O 3 , ...
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 ...
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
the subpopulations. This process enhances the genetic divergence among these subpopulations, favouring the emergence of genetic barriers and the formation of separate cohesive genotypic clusters. Indeed, recombination rates decrease drastically with sequence divergence10,11,12. This is due to the absence ...
Comparing to a generic two-state model, our models can distinguish class I from class II MHCs and correlate their structural parameters with the TCR/pMHC’s potency to trigger T cell activation. The models are tested by mutagenesis using an MHC and a TCR mutated to alter conformation changes....
