the mass and charge on either side of the reaction are equal. chemical equations for mass and charge are usually balanced in aqueous solutions. on both sides of the equation, balancing for mass yields the same number and types of atoms. when the net charge on both sides of the equation is...
Substituting pH for −log[H+] and pK′ for −log K′ yields (2.6)pH=pK′+log[A−][HA] or (2.7)pH=pK′+log[conjugatebase][acid] This relationship represents the Henderson–Hasselbalch equation. Since a buffer is intended to give only a small change in pH with added H+ or OH...

Rice yield potential is affected by at least four characteristics: panicles per unit area of land, number of spikelets per panicle, percentage of filled grains, and 1000-grain weight (KGW). Of these, KGW is a particularly complex trait that is determined by a combination of grain size-rela...
These results indicate that Anderson acceleration combined with warm-started initialization yields the most efficient solution method, though in the absence of initialization information, the nonsmooth Broyden method and Anderson acceleration perform comparably for the scale of problem in this example. Table...
Which of the following would be most appropriate for making forecast accuracy comparisons across different time series? a. Mean absolute percentage error b. Mean squared error c. Mean error d. Mean absolute error The following is a typical regre...
(y\), which is calculated as the proportion of the regression squares to the sum of total squares. The greater the goodness of fit, the higher the degree to which the argument interprets the cause variable, the higher the percentage of change caused by the argument to the total change, ...
The lateral flow, computed as a percentage of average annual rainfall. Groundwater contribution to stream flow (GW_Q) is the water from the shallow aquifer that returns to the reach during the time step and it varies widely among streams. The groundwater recharge values (GW_Q) for each ...
