Hey guys,can you guess a solid ,odorless , transparent , desiccant or drying agent which is capable of preventing things like medicine and other intake items from getting soggy ?This tiny thing is so common towards us that I think you all have guessed by now what I am talking about .Yes ,it’s Silica Gel. Silica gel is introduced to us by Chemistry Professor Walter A. Patrick.He has used it in a gas mask to absorb vapors and gases though it has been around since 1640 . It is a component of silicon dioxide which is naturally found in sand and also can absorb 30-40% of its weight in water. But do you know an interesting thing that silica gel beads are much similar to salt and sugar? Confusingly, sometimes both children and adults consume it without knowing whether it is toxic or not . Are you worrying about those who consume it ? let me help you . Though manufacturers often label them with “Do not eat” or “Throw away after using” sign, still consuming it won’t do harm . it will just exit ...

Carbon, one of the most well known elements in chemistry as well as our lives.People who don’t belong to chemistry or chemical science,also have heard the name ‘Carbon’ as we can find this element from photosynthesis to greenhouse gas.Seems cool, yeah? However,carbon can be called multitasker  as it shows multiforms.Then let’s get to the obvious meaning about its multiforms i.e 'Allotropes'.Well,allotrope refers to one or more physical forms of a chemical element which is different in terms of arrangement of atoms. Different forms of the same element are called allotrope along with differences in chemical and physical properties. Carbon has many allotropes because of its valency. Mainly there are 3 allotropes in pure carbon.They are: Diamond, graphite, fullerene(which includes nanotubes and "buckyballs").Also in amorphous form carbon's allotropes are:coal,coke,wood charcoal,animal charcoal,lamp black,gas carbon,petroleum coke,sugar charcoal.
