Animal charcoal differs from wood charcoal in that it
The question is asking how animal charcoal differs from wood charcoal. The options given are: dark colour, high carbon content, good absorbent, crystalline, and rich in phosphate content. The correct answer is E. that animal charcoal is rich in phosphate content.
Phosphate is a chemical compound that contains phosphorus, a non-metallic element that is essential for life. Phosphorus is found in many biological molecules, including DNA and ATP. It is also important for plant growth and is often a component of fertilizers.
Animal charcoal is made from animal bones, while wood charcoal is made from wood. Animal bones contain calcium phosphate, which is a type of phosphate that is rich in calcium. During the process of making animal charcoal, the bones are heated in the absence of air, which causes the organic material to burn off and leaves behind the calcium phosphate. This is why animal charcoal is rich in phosphate content.
In contrast, wood charcoal is not typically rich in phosphate content. It is produced by heating wood in the absence of air commonly called destructive distillation of wood, which causes the organic material to break down into carbon and other compounds. Wood charcoal is often used as a fuel and for cooking, as it burns hotter and longer than regular wood.
To summarize, animal charcoal differs from wood charcoal in that it is rich in phosphate content due to its production from animal bones, while wood charcoal is made from wood and is not typically rich in phosphate content bacause wood does not produce phosphate.
