It is possible to come to a conclusion and come to an inference. Both of them require that you process information and use it to form a judgment, but they occur at different points in the thought process. This means that there is a difference in the way that you use the two. Explore ...
Weight out about 3.5 grams of solid sodium nitrite on a balance and transfer it to a small cup or flask. Add about 50 mL of water to the flask or cup and swirl or stir the contents until the sodium nitrite completely dissolves. Transfer the solution to a 100-mL graduated cylinder and ...
Difference Between Pure Substance and Mixture - Introduction Pure substances are elements that cannot be broken further like oxygen, metals and metals, non-metals, etc. In contrast, mixtures are combinations of two or more elements mixed like lemonade. W
Non-metals are natural elements which do not have metallic properties. Often, they are available in the solid or gaseous state. In this type of elements, bromine is an exception as it exists in liquid state. They are good insulators of electricity and heat, non-lustrous (iodine is an excep...
conductors of heat and electricity. Non-metals maybe solids, liquid or gases at room temperature. Non metals have four to eight electrons. Non metals are very good oxidising agents but they are very brittle and have low density. Example: hydrogen, helium, phosphorus, iodine,carbonare some non...
Antiseptics may include alcohol, iodine, and hydrogen peroxide, which are used in lower concentrations to avoid tissue damage. Disinfectants can include similar substances but at higher concentrations, as well as other chemicals like bleach and quaternary ammonium compounds, which are not safe for use...

The second-to-last column of the periodic table of the elements belongs to the halogens, a class containing fluorine, chlorine, bromine and iodine. In their halide form, halogens create compounds with other ions. Halogens Halogens, a series of atomic ele
As fingers proceed downwards, the concentration of sodium iodine in fingers are reduced. As a result the convective mixing is rapidly suppressed. With an increase in the density difference and the permeability, the development of the natural convection occurs more quickly. The standard deviation of ...
Secondary antibodies used were Alexa Fluor488 conjugated donkey anti-mouse IgG (1:300, Molecular Probes, Eugene, OR), Cy3 conjugated donkey anti-rabbit IgG (1:300, Jackson Lab, West Grove PA) and TO-PRO3 Iodine (Molecular Probes). Retinas were visualized with four stitched images taken at ...
