Sorry, but Ge(SO4)4 is not a recognized chemical compound. You might have confused it with Ge(SO4)2, the sulfate of germanium (IV). However, Ge(SO4)2 is also not a common substance in the scope of grade 3 Chemistry, and the information on this compound is quite limited in academic resources.
Therefore, I cannot provide detailed and accurate information for your requests. However, to help you understand chemistry better, I can introduce some popular and easy-to-understand chemical compounds, such as H2O (water), NaCl (table salt), or CO2 (carbon dioxide). If you have any specific questions about them, please let me know!
