The structure of graphite accounts for the design of graphite electrodes in the sense that the tight structural composition of graphite makes it easy for them to be arranged in electrodes.
Graphite has an extremely low reactivity. Graphite can react with oxygen and sulfuric acid.
Graphite is pure carbon. A diamond is also pure carbon in a very specific crystal. Yet diamonds do not conduct electricity and graphite does. Graphite can form in plate like arrays of hexagonal crystals and in an amorphous, powdery form.
Graphite is an element. It is a form of carbon.
Graphite is not magnetic as it is made out of carbon. E.g; Pencil lead is mostly made out of graphite, it is NOT magnetic.
how to convert proximate analysis of coal to ultimate analysis
proximate analysis of fat can be done by using soxhlet apparatus
no difference
Proximate analysis is important because it is one of the most effective ways to analyze nutritional value and energy value in food.
We do proximate analysis of the matter to know the nitrogen (protein), oil (fat), mineral, ash content etc to have an idea about the energy contained in that matter.
practically there is no difference ..bt theoretically it has ...... ultimate analysis leads to the total summation while the proximate leads to the avg value .....
because the proximate is just to find the crude one only and they are denatured by heat.
in proximate analysis of food, you determine for moisture content in the food, you determine for ashing, you determine for protein, crude fiber and so on
is amethod used to improve the analysis of proximate methods
Nutrition analysis became an essential part of most food labels after enactment of the Fair Packaging and Labeling Act. In 1994 the nutrient content label was changed to Nutrition Facts. Nutrition analysis determines the quantity and type of nutrients in a food. A food's nutrient content is analyzed by proximate analysis. Proximate or chemical analysis measures carbohydrate, fat, and protein content of a known quantity of food. Results are entered in a nutrient database which is used to generate Nutrition Facts labels. Professional organizations such as the Association of Official Analytic Chemists (AOAC) publish official methods of proximate analysis.
its answer is oxygen because pyrogallol absorbs oxygen so used to measure amount of oxygen in any substance
