Answer: D. 1600 L

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 6.023\times 10^{23} of particles.

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given volume}}{\text {Molar volume}}

\text{Number of moles of nitrogen}==\frac{1000L}{22.4L}=44.6moles

\text{Number of moles of hydrogen}==\frac{2400L}{22.4L}=107.1moles

N_2(g)+3H_2(g)\rightarrow 2NH_3(g)  

According to stoichiometry :

3 moles of H_2 require 1 mole of N_2

Thus 107.1 moles of H_2 will require=\frac{1}{3}\times 107.1=35.7moles of N_2

Thus H_2 is the limiting reagent as it limits the formation of product and N_2 is the excess reagent.

As 3 moles of H_2 give = 2 moles of NH_3

Thus 107.1 moles of H_2 give =\frac{2}{3}\times 107.1=71.4moles  of NH_3

Volume of NH_3=moles\times {\text {Molar volume}}=71.4moles\times 22.4L/mol=1600L

Thus volume of ammonia produced is 1600 L

Calculate the density of chlorine gas in g/l, at stp.
vichka [17]
The Answer would be e: 3.2 g/L 

<span>At STP : p = 1 atm and T = 273.15 K 
molar mass Cl2 = 70.906 g/mol 

d = molar mass x p/RT = 70.906 x 1 atm / 0.08206 x 273.15=3.16 g/L</span>

A pure substance contains only one type of particle.?
Alenkinab [10]

Answer:

element

A pure substance is matter that is uniform throughout and has consistent properties. All matter is made up of very small particles called atoms. Atoms are the building blocks of all matter. When a substance contains only one type of atom, it is called an element.
