In a chemical equation, the coefficient of substance C is 4 and the coefficient of substance D is 2. What is the ratio of the number of moles of C to D? A. 1:2 B. 2:1 C. 3:1 D. 4:1 相关知识点: 试题来源: 解析 B。系数之比等于物质的量之比,所以 C 和 D 的物质的量...
A key assumption of polymer physics is that the random chain polymers extend in flow. Recent experimental evidence has shown that polymer chains compress in Couette flow in a manner counter to expectation. Here, scaling arguments and experimental evidence from the literature are used to determine th...
How to balance the following chemical equation with the right coefficient? CH3OH + O2 = CO2 + H2O Balance the chemical equation. C3H8 + O2 --%3E CO2 + H2O Balance all terms in the equations: V_2O_5+Al \to Al_2O_3+V \\ C_7H_{10}N + O2 \to CO_2 + H...
Stochastic biochemical reaction networks are commonly modelled by the chemical master equation, and can be simulated as first order linear differential equations through a finite state projection. Due to the very high state space dimension of these equat
A linear regression on the chemical contribution to MD was conducted to determine the regression coefficient and the average diameter increase rate. The following equations were derived: $${\rm{MD}}\,{\rm{Increase}}\,{\rm{Rate}}=1.76\cdot {\rm{Chemical}}\,{\rm{contribution}}\,({\rm{...
with the velocity fieldv, the rotational diffusion coefficientDR, the free energy densityf, its derivative\({f}^{{\prime} }={\partial }_{\rho }\,f\), the particle massm, the friction coefficientγ = 1/(mM), and the local density-dependent swimming speed ...
Moreover, the measured piperonylonitrile solubility was fitted with Wilson, NRTL, UNIQUAC, Two-Suffix Margules and NRTL-SAC model, and correlation of experimental results with the use of five activity coefficient models showed that sufficient agreement with the calculated data. Finally, the ...
Briefly, the cophenetic correlation coefficient is used as a measure of the robustness of the method in producing stable groups of genes from different random initializations for a given number of factors (k). Based on this estimation, a value of k = 8 was selected from a set of 100 ...
The coefficient of determination R2 was used to quantify how well the model describes the measured data. Moreover, the effect of saturation was statistically analyzed for carbonate rock by considering four different saturation conditions. First, keeping porosity constant, the major mineral composition ...
