How many grams of oxygen are needed to react completely with 200.0 g of ammonia, nh3? 4nh3(g) + 5o2(g) ? 4no(g) + 6h2o(g)?

Answer : The mass of oxygen needed are 470.592 grams.

Solution : Given,

Mass of = 200.0 g

Molar mass of = 17 g/mole

Molar mass of = 32 g/mole

First we have to calculate the moles of .

Now we have to calculate the moles of  

The balanced chemical reaction is,

From the reaction, we conclude that

As, 4 mole of react with 5 mole of

So, 11.765 moles of react with moles of

Now we have to calculate the mass of

Therefore, the mass of oxygen needed are 470.592 grams.

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.
