For example, a differential equation form of the Logistic model would take the form dX/dt = r*X*(1-X/K). To solve this model with Stella we note that both sides of this equation represent the change in population size, just as X(i+1) - X(i) does in the difference equation models. Consequently, the right hand side of the differential equation is

14/01/2015· where M i is the relative molar mass (kg mol-1) of species i.. The diffusive mass flux of each species is, in turn, expressed based on the gradients of the mole or mass fractions, using multi-component diffusion coefficients D ik.These are symmetric, so that an n-component system requires n(n-1)/2 independent coefficients to parameterize the rate of diffusion of its components.

A conventional balanced equation with integer-only coefficients is derived by multiplying each coefficient by 2: [latex]2{\text{C}}_{2}{\text{H}}_{6}+7{\text{O}}_{2}\rightarrow 6{\text{H}}_{2}\text{O}+4{\text{CO}}_{2}[/latex] Finally with regard to balanced equations, recall that convention dictates use of the smallest whole-nuer coefficients. Although the equation for the …

Write a complete,balanced equation to represent the formation of manganese-55 by the beta decay of another nuclide.
