WebThe main impurity is CO 3 2− (3–8 wt%), and the minor impurities are Na +, Mg 2+, K +, HPO 4 −, Cl −, and F −, for example. With the exception of F − , they weaken the structure and make it more soluble. 5 Moreover, they change the lattice parameters, crystal morphology, crystallinity, solubility, thermal stability, and bioactivity.

It can be odd+even or even +odd. m can be even or odd. Not sufficient. (2) n + m = n^2 + 5. Let's suppose n is odd, n^2 will also be odd. Hence to maintain the equality m must be odd. Let's suppose n is even, n^2 will be even. And to maintain the equality m must be odd. symbol of wavenumberWebA Simple Proof by Contradiction Theorem: If n is an integer and n2 is even, then n is even. Proof: By contradiction; assume n is an integer and n2 is even, but that n is odd. Since n is odd, n = 2k + 1 for some integer k. Then n2 = (2k + 1)2 = 4k2 + 4k + 1 = 2(2k2 + 2k) + 1.
