11. There is also a spherical tank that contains the hydrazine monopropellant fuel. 12. However, hydrazine is also the most expensive and toxic. 13. Experts debated whether the hydrazine tank would have survived an uncontrolled reentry. 14. The tank contained 133 kg ( 293 lb ) of purified hydrazine . 15. Camera observations required turning the spacecraft, which consumed precious hydrazine fuel. 16. Each fuel supply module ( tank ) contained of hydrazine . 17. This reagent can be prepared by reaction of tosyl chloride with hydrazine . 18. Dihydrazides are made by the reaction of an organic acid with hydrazine . 19. Potassium hexachloroplatinate may be reduced by hydrazine corresponding tetrachloroplatinate salt. 20. In sufficiently high concentration, azanyl dimerises to form hydrazine .
