Based on the arrangements of constituent particles, solids can be classified into two types, called crystalline solids and amorphous solids. A crystalline solid is a solid in which the constituent particles are arranged in regular three-dimension...
Which of these properties describes a metal? a. brittle b. conducts heat very well c. fragile d. transparent Elements: Element is a substance that can exist as a single identifiable unit and can be broken down into simpler substances. The periodic table list...
There are four types of crystalline solids:ionic solids, molecular solids, network covalent solids and metallic solids. Is NaCl a crystalline solid? Acrystalline solidis a solid that has a regular, repeating three-dimensional structure. A crystal of NaCl (Figure 14.5. 1) is one example: at th...
LCD stands for Liquid Crystal Display. This technology uses liquid crystals, which are substances with properties of both liquids and solids, to create images on a screen. When an electric current is applied, the liquid crystals align to allow or block light, creating the images you see on th...
Synthetic zwitterionic detergent, which unlike other amphoteric surfactants, retains its zwitterionic character over a wide pH range. This property is attributed to the presence of both a strongly basic quaternary ammonium ion and an acidic sulfonate ion of equal strength. This ionic balance presumably...
Explain why ionic compounds have higher melting and boiling points compared to those of molecular or covalent compounds. Predict which type of intermolecular bonding the following substances will have. a. Br2 b. HBr c. NBr3 Which property is a characteristic of an ion...
and casein, as displacement ones of BSA, as the material in order coat to do the solid phase and the especially magnetic grain which are used in the immunity assay and the other join assay for separating analysis ones of desire, or, it was discovered that it is useful in addition to ...
PROBLEM TO BE SOLVED: To surely prevent firing of zircaloy fine in the compression and the transfer to a capsule carrying-out vessel with excellent remote controllability and maintenance property by charging a capsule into a cavity from the lower part, and pressing it by a pressing bar to compr...
What is a property of metals? What is the source of the energy that allows a fluid in a capillary (e.g., a thin, hollow, glass tube) to rise? What is the effect of temperature on the viscosity of a liquid? Which puts out the greater percentage of its energy as light, ...
Another important property of amylose is the fact that it is a chiral molecule. Due to the chirality it may preferably be used after immobilization, e.g. on a column for separating enantiomers. Furthermore, it was surprisingly found that starch which may be isolated from potato plants in wh...
