Imagine that you were an ecologist need to estimate the number of spiders in Abeling 500 m² of a rainforest please explain the procedure you would follow to get your estimate including hypothetical data

When sand is coated with a layer of trimethylhydroxysilane, (ch3)3sioh, it repels water and can no longer get wet. hydrophobic sand (aka, magic sand) is fun to play with, but it can also have useful applications in agriculture to reduce water consumption. predict the geometry for the silicon atom in trimethylhydroxysilane.
