ya yes its there a matrix called zero matrix
A zero matrix is a matrix in which all of the entries are zero.
A sparse matrix is a matrix in which most of the elements are zero.
a squar matrix A is called involutary matrix. if A^2=I
yes, it is true that the transpose of the transpose of a matrix is the original matrix
This is the Archimedes principle.
Risk Assessment Matrix
that is a biology question. the bony matrix is the principle tissue of mature bones. trabecular bone is spongy bone ,which is less dense than compact bone.
Lead sulfide is a black solution. It is insoluble in water and is a precipitate. The principle of the lead acetate test is the formation of lead sulfide.
Ion exchange resin is used in separation, purifying and decontamination processes. The resin is an insoluble matrix. They are usually made of cross-linked polystyrene molecules.
INSOLUBLE
Dye colorants are soluble substances that penetrate and dye materials, while pigments are insoluble particles that are suspended in a medium to give color. Dyes are usually transparent and can produce a wider range of hues, while pigments are more opaque and offer better lightfastness and stability.
The principle that governs precipitation reactions is the formation of an insoluble solid (precipitate) when two solutions are mixed and a solid is formed due to the reaction of the ions in the solutions. This occurs because the product of the reaction is not soluble in the solution.
Insoluble
Soluble impurities (that is, impurities that are included within the crystal matrix) tend to lower the observed melting point and broaden the melting point range. Insoluble impurities have no effect on the melting point. Found from website: http://swc2.hccs.edu/pahlavan/2423L1.pdf
The Dragendorff reagent principle is based on the formation of an insoluble complex between bismuth iodide and alkaloids, which results in a distinctive orange to reddish-brown color precipitation. This reaction is commonly used in chemistry and biochemistry to detect the presence of alkaloids, specifically in plant extracts.
Pepper is insoluble.
