Zn as a limiting reactant

N₂ as an excess reactant

Theoretical Yield : 13.15 g

<h3>Further explanation</h3>

Reaction

3 Zn + N₂ ⇒ Zn₃N₂

Ar Zn : 65,38 g/mol

Ar N₂ : 28.0134 g/mol

mol Zn

\tt \dfrac{11.5}{65.38}=0.176

mol N₂

\tt \dfrac{9.55}{28.0134}=0.341

limiting reactant : the smaller ratio(mol:coefficient)

mol ratio Zn : N₂ :

\tt \dfrac{0.176}{3}\div \dfrac{0341}{1}=0.0586\div 0.341

Zn as a limiting reactant(smaller ratio)

N₂ as an excess reactant

mol Zn₃N₂ :

\tt \dfrac{1}{3}\times 0.176=0.0586

mass of Zn₃N₂ (Theoretical Yield) :

\tt 0.0586\times 224.154~g/mol=13.15~g

Based on the three formulas shown, use one of them to solve for the purple yellow and red box and explain how you did it.
zysi [14]

P = 11.133 atm (purple)

T = -236.733 °C(yellow)

n = 0.174 mol(red)

<h3>Further explanation  </h3>

Some of the laws regarding gas, can apply to ideal gas (volume expansion does not occur when the gas is heated),:  

  • Boyle's law at constant T, P = 1 / V  
  • Charles's law, at constant P, V = T  
  • Avogadro's law, at constant P and T, V = n  

So that the three laws can be combined into a single gas equation, the ideal gas equation  

In general, the gas equation can be written  

\large {\boxed {\bold {PV = nRT}}}

where  

P = pressure, atm  

V = volume, liter  

n = number of moles  

R = gas constant = 0.08206 L.atm / mol K  

T = temperature, Kelvin  

To choose the formula used, we refer to the data provided

Because the data provided are temperature, pressure, volume and moles, than we use the formula PV = nRT

  • Purple box

T= 10 +273.15 = 373.15 K

V=5.5 L

n=2 mol

\tt P=\dfrac{nRT}{V}\\\\P=\dfrac{2\times 0.08205\times 373.15}{5.5}\\\\P=11.133~atm

  • Yellow box

V=8.3 L

P=1.8 atm

n=5 mol

\tt T=\dfrac{PV}{nR}\\\\T=\dfrac{1.8\times 8.3}{5\times 0.08205}\\\\T=36.42~K=-236.733^oC

  • Red box

T = 12 + 273.15 = 285.15 K

V=3.4 L

P=1.2 atm

\tt n=\dfrac{PV}{RT}\\\\n=\dfrac{1.2\times 3.4}{0.08205\times 285.15}\\\\n=0.174~mol

Which contains more molecules; a mole of Chlorine gas (Cl2 ) or a mole of glucose (C6H1206) ?
Elodia [21]
This is a tricky question. a mole of any compound contains the same number of molecules of that certain compound. so, one mole of chlorine gas has the same number of molecules as one mole of glucose, which is 6.02 x 10^23.

this is avogadro's number and it applies for any mole of molecules. 

the question is tricky because it is like asking. " what weighs more, a pound of feathers or a pound of rocks?" the both weigh the same, a pound. when ewe talking about moles, same as pounds, it is a quantity unit. one mole will aways be equal to 6.02 x 10^23 molecules.
