Cobalt-57 has a half-life of about 272 days. If a sample has an initial mass of 2.24 g and undergoes decay until it has a mass of 0.140 g, how many half-lives passed? A first-order reaction (A \to B) has a half-life of 30 minutes. If the initial concentration of A is 0.500...
For the reaction below, Delta H=760.4kJ/mole of S8 and Delta S=1219.1 J/(K*mole of S8).Calculate the equilibrium constant at 210C and at 440C.4CH4(g) + S8(s) <-> 4CS2(g) + 8H2(g)For the reaction of CH4 with S8 to form CS2 and H2, we are given Delta H= 150.3 kJ/mol...
Find the energy of the reaction: 2H_2 + O_2 to 2H_2O Delta H = -486 kJ/mol Find the energy of the reaction: N_2 + 2O_2 to 2NO_2 Delta H = +68 kJ/mol For which of the following is the standard free energy of formation equal to zero (Delta G_f = 0)...
Both of these modern concepts are needed to really get to the more modern Delta G = - RTlnKeq in a satisfying way.The term ΣμidNi is a term added to the equation to account for the changes in material equilibrium. When a chemical reaction occurs the material composition of a system ...
The orbiter consists of the following parts: crew compartment - where you will live and work forward fuselage (upper, lower parts) - contains support equipment (fuel cells, gas tanks) for crew compartment forward reaction control system (RCS) module - contains forward rocket jets for turning the...
Higher values can be used in case of noisy boards (in this case, the reaction to real OCP2 events is slower). LLC OC2 detection Size: 1 bit Enables / disables the LLC OC2 comparator. Available values are: 3.2.6 . Disabled . Enabled The LLC OC2 comparator is connecte...
Back in the 1990s, Philip Strong was able not only to describe the psychological impact of epidemics on social order but also to model it. He observed that the early reaction to major fatal epidemics is a distinctive psycho-social form and can be modeled along three main dimensions: fear, ...
According to the so-called Lockean thesis, a rational agent believes a proposition just in case its probability is sufficiently high, i.e., greater than so
The delta-delta Ct method, also known as the 2–∆∆Ct method, is a simple formula used in order to calculate the relative fold gene expression of samples when performing real-time polymerase chain reaction (also known as qPCR). The method was devised by Kenneth Livak and Thomas Schmittg...
