Hydrazine, a highly toxic chemical compound, derives its name from the Greek word "hydr-", meaning water, and "azine", which refers to a nitrogen compound. Its chemical formula is N2H4. Hydrazine has numerous chemical and physical properties, including a highly flammable liquid at room temperature and the ability to dissolve a wide range of substances.

Its plural form is "hydrazines", while its past participle and adjective forms are "hydrazinated" and "hydrazine-like", respectively. Hydrazine is also known for its use in rocket fuel and other high-energy applications.

In terms of related words, we can mention "hydrazinolysis", a chemical reaction in which hydrazine is used to break down chemical bonds; "hydrazinocarbonyl", a chemical compound containing hydrazine; and "hydrazinofluorene", a derivative of hydrazine that is used in the treatment of leukemia.

Hydrazine is a highly dangerous chemical compound that should be handled with the utmost care.

英文小作文：

Hydrazine is a highly reactive chemical that is commonly used in rocket propulsion and other high-tech fields. It is a colorless gas that is highly toxic and must be handled with extreme caution. However, when used properly, hydrazine can be a powerful fuel that can propel rockets to incredible speeds and altitudes.

Hydrazine-powered rockets are commonly used in space exploration and other high-altitude missions, where they can reach speeds of over 20,000 kilometers per hour and achieve altitudes of thousands of kilometers above the Earth"s surface. However, the use of hydrazine is also associated with significant risks, as it can cause serious harm or even death if not handled properly.

Therefore, it is crucial to ensure that the proper safety measures are taken when using hydrazine, including proper ventilation, wearing protective equipment, and following all safety regulations and procedures. In conclusion, while hydrazine has many valuable applications, it must be handled with the utmost care to ensure the safety of both personnel and the environment.
