One example of rocket fuel is the reaction of hydrazine with dinitrogen tetroxide.
2N2H4(1) + N204(9) - 3N2(g) + 4H2O(g) + heat
->
This reaction is hypergolic, meaning it does not need an external ignition
source, and highly exothermic. 1.000 liter of hydrazine is reacted with
excess dinitrogen tetroxide. The density of hydrazine is 1.021 g/mL, and
the molar mass is 32.0452 g/mol.
How many moles of water could be produced?

what is the general relationship between a galaxy's distance from earth and its speed?

the answer is:

the farther away a galaxy is from us, the faster it is moving away from us.

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
