Why is carbon chemistry clearly complex?

Sodium thiosulfate pentahydrate is used in iodine-clock reactions and iodometric titration experiments. Write the chemical formula for sodium thiosulfate pentahydrate.

Explain the difference in the boiling points of NO2 (21º C) and N2O (-88º C). Use the Lewis structures to support your explanation.

what are interhalogen compounds ?

Briefly explain the term ‘chemoselectivity’

Write the acidic equilibrium equation for CSHSNH.

Consider the equilibrium, CO2(g) + H2(g) < ---- > CO(g) + H2O(g). Calculate the equilibrium concentration of CO, given that the equilibrium constant, Kc, is 0.0049 and the equilibrium concentrations of H2O(g) is 0.46 M, that of H2(g) is 4.54 M, and that of CO2(g) is 9.54 M. Group of answer choices 0.46 M 10. M 0.098 M 2.2 M

5. When copper sulfate is dissolved in water, it forms a clear blue solution. What are the formulas of the two ions in this solution? A small amount of aqueous ammonia is added to this solution, and a light blue precipitate forms. What is the formula for this precipitate? The precipitate dissolves to form a dark blue solution when more ammonia is added. Why?

Because carbon and silicon are both elements in group 14 on the periodic table, we expect them to react with other elements in similar ways. To some extent, they do, but in some cases, carbon and silicon compounds that seem to have analogous structures have very different chemical characteristics. For example, carbon tetrachloride, CCl4, is very stable in the presence of water, but silicon tetrachloride, SiCl4, reacts quickly with water. The unbalanced equation for this reaction is SiCl4 + H2O → Si(OH)4 + HCl Balance this equation. Write a conversion factor that could be used to convert between moles of SiCl4 and moles of H2O. How many moles of SiCl4 react with 24 moles of water? Write a conversion factor that could be used to convert between moles of Si(OH)4 and moles of water. How many moles of Si(OH)4 form when 4.01 moles of H2O react with an excess of SiCl4?
