Oberon completes one (circular) orbit of Uranus in 13.5 days. The distance from Uranus to Oberon is 5.84×108m. What is the centripetal acceleration of Oberon?

When 1.20 mole of ammonia reacts, 1.8 moles of water are produced.

Explanation:

The balanced reaction is:

4 NH₃(g) + 5 O₂(g) → 4 NO (g) + 6 H₂O

By stoichiometry of the reaction, the following amounts of moles participate in the reaction:

Then you can apply the following rule of three: if by stoichiometry 4 moles of ammonia produce 6 moles of water, 1.2 moles of ammonia will produce how many moles of water?

moles of water= 1.8 moles

When 1.20 mole of ammonia reacts, 1.8 moles of water are produced.
