When nitrogen gas (N2) reacts with hydrogen gas(H) ammonia gas (NH3) is formed. How many grams of hydrogen gas are required to r
kupik [55]

Mass of Hydrogen gas required to react : 0.936 g

<h3>Further explanation</h3>

Reaction on Nitrogen gas and Hydrogen gas to produce Ammonia gas

N₂ (g) + 3 H₂ (g) ⇒ 2 NH₃ (g)

Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol

so mol Nitrogen for 3.5 L at STP :

\tt mol=\dfrac{3.5~L}{22.4~L}=0.156

From the equation, mol ratio of N₂ : H₂ = 1 : 3, so mol H₂ :

\tt \dfrac{3}{1}\times 0.156=0.468

then mass of Hydrogen(MW= 2 g/mol) :

\tt mass=mol\times MW\\\\mass=0.468\times 2\\\\mass=0.936~g

In the chemical formula 2so2, how many total atoms of sulfur (s) are there? 1 2 4
babunello [35]
Sulfur has the coefficient of 2, and nothing else. This indicates Sulfur has 2 atoms. 


<span>Oxygen on the other hand, has a subscript of 2, as well as the coefficient of 2. Multiplying those, and you see Oxygen has 4 atoms. 
</span>
So your answer is 2

Also remember there is a 2 in front of S meaning there are 2 Sulfurs. 
<span>If it was S02 it would be 1 Sulfur as there is no number in front of sulfer. </span>

<span>Remember the number in front of a element, represents how many atoms there are :)</span>
