The differences in the properties of diamond and graphite is as a result of how their particles are arranged in space. This space arrangement leads to distinct crystal structures for the two compounds. In diamond, the carbon atoms are arranged in tetrahedral shape while in graphite the carbon atoms arrayed in planes.
Hope this helps :)
In thermal cracking, high temperatures (typically in the range of 450°C to 750°C) and pressures (up to about 70 atmospheres) are used to break the large hydrocarbons into smaller ones. Thermal cracking gives mixtures of products containing high proportions of hydrocarbons with double bonds - alkenes.
Answer:
Filtering <span>is best laboratory technique to separate a solid from a liquid to recover the liquid.
Explanation:
A solid particles present in liquids can be separated from liquid by utilizing a membrane having pores large enough to allow the liquid molecules to pass through and small enough to stop the solid particles from crossing.
Example:
Tea Filters are used to separate Tea from the grounds.
Kidney is an excellent example of Biological Filter.
