When NH3(g) reacts with O2(g), the products of the combustion are NO(g) and H2O(g). What volume of O2(g) is required to react wi

arlik [135]

<u>Answer:</u> The volume of oxygen gas required is 3.75 mL

<u>Explanation:</u>

STP conditions:

1 mole of a gas occupies 22.4 L of volume.

We are given:

Volume of ammonia reacted = 3.00 mL = 0.003 L (Conversion factor: 1 L = 1000 mL)

The chemical equation for the reaction of ammonia with oxygen follows:

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

By Stoichiometry of the reaction:

(4 × 22.4) L of ammonia reacts with (5 × 22.4) L of oxygen gas

So, 0.003 L of ammonia will react with = $\frac{(5\times 22.4)}{(4\times 22.4)}\times 0.003=0.00375L=3.75mL$ of oxygen gas

Hence, the volume of oxygen gas required is 3.75 mL

What happens to a linguist when it releases enough energy

Ugo [173]

Answer:

When a liquid releases enough energy, the liquid will freeze and turn into a solid. Phase changes are what causes one state of matter to turn into another. ... Phase changes occur because of changes in the amount of kinetic energy obtained by the particles that make up a substance. Kinetic energy is the energy of movement.
