A mixture of hydrazine, hydrogen and Cu(II) catalyst is used as rocked

1.	A mixture of hydrazine, hydrogen and Cu(II) catalyst is used as rocked fuel. Why?
Answer» Solution :In the presence of `Cu(II)` catalyst, hydrogen peroxide hydraine `(NH_(2)-NH_(2))` to NITROGEN. The reaction is HIGHLY exothermic and in accompanied by large increasein volume. Therefore, the mixture provides an upward and thrust and is used to a rocket FUEL. `NH_(2)-NH_(2)(l)+2H_(2)O_(2)(l) UNDERSET("Heat")overset("Cu(II)")to N_(2)(g)+4H_(2)O(g)+"heat"`
