Hello friends, welcome to Lido's online Homework solving session this is neha and today we'll be looking in the following question the question says tabulate a comparative the chart to differentiate between elements Composed mixtures differentiate them with reference to the Term Existence the properties and separation of components so in this question, we have to tabulate a comparative chart that will differentiate between elements compounds and mixtures and we have to differentiate them in the following reference to the term existing properties and separation so Let's look at it one by one. so first let's define it in reference to The Term an element is a basic unit of matter. which is a pure substance What I mean by pure substance pure substance means was which cannot be broken down into a simpler substance so this is pure substance for example iron-sulfur compounds compound it is a pure substance compounds mean the combination of two or more elements these are called compound and mixture it is basically an impure substance so compounds and elements, these are pure substances and the mixture is an impure substance which comprises a a combination of two or more elements or compounds of both for example iron and sulfur so this is a Mixment and it's an impure substance existence now how existence means how do they exist so they exist independently and this In the case of compounds, they are combined in the fixed ratio like for example, water water is combined in the fixed ratio and that is what we call it as compound and mixture means elements and compounds are mixed in any ratio so here as it is independent here it is mixed fixed ratio and here it is mixed in any ratio now let's look at the third reference Point out it is the properties they have definite set of properties and in case of compound the elements of the compounds do not retain their properties These are the properties of the original elements and the mixture the components of the mixture retain their properties next is the separation elements cannot be broken down into simpler substances In the case of elements and for example, you can take iron-sulfur as they all exist independently elements cannot be broken down into a Simple substance compounds elements can be separated from compounds by a chemical method so we can separate the elements from a compound using some chemical methods and mixing components of the the mixture can be separated by physical methods light for example uh iron and sulfur is an example of mixture so with the help of the properties of magnetization we can sell for a separate iron from sulfur compound Examples of water and carbon dioxide and elements which exist independently are iron and sulfur so this is how we approach this question. hope you understood the solution in case if you have any doubts, please feel free to drop a comment below and subscribe to the channel for regular Update Thank you
