To solve, you find the correct mole ratio from the given equation. The questions asks for how many moles of H2O from 2.0 moles of NH3(ammonia), so the mole ration is going to be 6:4.
6 moles of  H2O and 4 moles of NH3.

<u>Tip:</u>
We multiply the given with what we want divided by what we want to get rid of.

So, 2.0mol NH3 x 6mol H2O /4mol NH3.


The answer is  3 moles of H2O or 3mol H2O

Answer : The number of moles of H_2O formed is, 3 moles

Solution : Given,

Moles of NH_3 = 2.0 moles

Now we have to calculate the moles of H_2O

The given balanced chemical reaction is,

4NH_3(g)+5O_2(g)\rightarrow 4NO(g)+6H_2O(g)

From the balanced reaction, we conclude that

As, 4 moles of NH_3 react to give 6 moles of H_2O

So, 2.0 moles of NH_3 react to give \frac{6}{4}\times 2.0=3 moles of H_2O

Therefore, the number of moles of H_2O formed is, 3 moles

ale4655 [162]

Answer:

E = 16 J

Explanation:

We have,

You put scruffy can run up to 2 m/s on his fastest days scruffy has a mass of 8 kg

It is required to find the maximum kinetic energy on his fastest days. If v is the velocity, then kinetic energy is given by :

E=\dfrac{1}{2}mv^2

Plugging all the values,

E=\dfrac{1}{2}\times 8\times 2^2 \\\\E=16\ J

So, the maximum kinetic energy on his fastest day is 16 J.
