In the above, we note that the stoichiometric number of a reactant is negative. Now when we know the extent, we can rearrange the equation and calculate the equilibrium amounts of B and C. n e q u i , i = ξ e q u i ν i + n i n i t i a l , i {\displaystyle n_{equi,i}=\xi _{equi}\nu _{i}+n_{initial,i}}
1/K 1 =1/ k 11 + 1/k 12, and therefore K 1 = k 11 k 12 / ( k 11 + k 12 ). Thus, in this example there are four micro-constants whose values are subject to two constraints; in consequence, only the two macro-constant values, for K 1 and K 2 can be derived from experimental data.
The coulomb was originally defined, using the latter definition of the ampere, as 1 A × 1 s. [4] The 2019 redefinition of the ampere and other SI base units fixed the numerical value of the elementary charge when expressed in coulombs and therefore fixed the value of the coulomb when expressed as a multiple of the fundamental charge.
The plus sign (+) is a binary operator that indicates addition, as in 2 + 3 = 5. It can also serve as a unary operator that leaves its operand unchanged (+x means the same as x). This notation may be used when it is desired to emphasize the positiveness of a number, especially in contrast with the negative numbers (+5 versus −5).
These can be quite elaborate in the case of certain maize varieties, but tend to use a trapezoidal or leaf area index (LAI) curve for common crop or vegetation canopies. Stress coefficients, K s, account for diminished ET due to specific stress factors. These are often assumed to combine by multiplication.

A closely related parameter, also often used for sediment transport under water waves, is the displacement parameter δ: [1] δ = A L , {\displaystyle \delta ={\frac {A}{L}},} with A the excursion amplitude of fluid particles in oscillatory flow and L a characteristic diameter of the sediment material.
On the other hand, if such a tiling uses exactly k of the 2 × 1 tiles, then it uses n − 2k of the 1 × 1 tiles, and so uses n − k tiles total. There are ( n − k k ) {\displaystyle {\tbinom {n-k}{k}}} ways to order these tiles, and so summing this coefficient over all possible values of k gives the identity.
