What is the volume, in ml, of 0.183 mol NH3? (at STP).
Tems11 [23]

The volume of ammonia gas is 4096 mL.

Explanation:

As per the kinetic theory of gases, the volume occupied by gas molecules will be directly proportional to the temperature and number of moles of the gas molecules. Similarly, the volume occupied by gas molecules will be inversely proportional to pressure.

PV = nRT

So, V = nRT/P

As R = 0.082 L atm mol⁻¹ K⁻¹ , T = 273 K and P = 1 atm with n = 0.183 mol

Then,

V=(0.183*0.082*273)/1

V = 4.096 L = 4096 mL.

Thus, the volume of ammonia gas is 4096 mL.

lutik1710 [3]

Answer:

The release of methane from thawed permafrost.

Explanation:

The complete question is

A group of scientists in Alaska notices that not only have atmospheric CO2 levels increased at their sampling site but so too have methane levels. What could account for this increase in methane levels?

- None of the answer options is correct.

- The release of methane from thawed permafrost.

-A decrease in beef production near the researchers' sampling area.

-The melting of permafrost accompanied by the thawing of methane-producing bacteria.

-The failure of rice paddies to be established in Alaska, given its climate.

Permafrost regions like the arctic circle hold a large supply supply of methane in their soils and their seas. Ordinarily, this methane should be gradually released naturally over a long period of time, but the effects of global warming is making these permafrost to thaw at a much faster rate, accelerating the release of methane into the atmosphere. The dark side is that methane is about 80 times more deadly when compared to CO2 in its contribution to the green house effect on earth.

Consider the balanced equation below. 4nh3 3o2 right arrow. 2n2 6h2o what is the mole ratio of nh3 to n2? 2:4 4:2 4:4 7:2
KIM [24]

The required mole ratio of  NH₃ to N₂ in the given chemical reaction is 2:4.

<h3>What is the stoichiometry?</h3>

Stoichiometry of the reaction gives idea about the number of entities present on the reaction before and after the reaction.

Given chemical reaction is:

4NH₃ + 3O₂ → 2N₂ + 6H₂O

From the stoichiometry of the reaction it is clear that:

4 moles of NH₃ = produces 2 moles of N₂

Mole ratio NH₃ to N₂ is 2:4.

Hence required mole ratio is 2:4.
