Answer:
3.53*
Explanation:
![K_{c} =\frac{[HI]^{2}[Cl_{2}] }{[HCl]^{2}}=\frac{[5.6*10^{-16} ]^{2} [0.0019]}{[0.13]^{2} }=3.53*10^{-32}](https://tex.z-dn.net/?f=K_%7Bc%7D%20%3D%5Cfrac%7B%5BHI%5D%5E%7B2%7D%5BCl_%7B2%7D%5D%20%7D%7B%5BHCl%5D%5E%7B2%7D%7D%3D%5Cfrac%7B%5B5.6%2A10%5E%7B-16%7D%20%5D%5E%7B2%7D%20%5B0.0019%5D%7D%7B%5B0.13%5D%5E%7B2%7D%20%7D%3D3.53%2A10%5E%7B-32%7D)
Kc is the equilibrium constant calculated as the ration of products over reactants with their stoichiometric coefficients as their exponents. So the balanced chemical equation is important. Solids do not form part of the Kc expression, they do not affect the equilibrium constant which is why Iodine is not part of the calculations
Polar molecules are molecules are essentially have no molecular symmetry.
Nonpolar molecules are molecules that have molecular symmetry.
Water is a very basic example of a polar molecule.
The ideal gas equation is PV = nRT. if you are looking
for the volume of the chlorine gas then the equation will turn out to be V =
nRT/P. At STP, temperature is 273K and pressure is 1 atm.
V = nRT/P
V = (1.5 moles Cl2)(0.08206 L-atm/mol – K)(273K) / (1atm)
V = 33.6 liters
Answer:
= 6.21x10^21
Explanation:
It's the train track method, where you try to cancel all the units and end with units that you need. Here we want to end with number of atoms of N.
500 mg N x 1 g N/1000 mg N x 1 mol N/194.19 g N x 4 mol N/1 mol of caffeine x (6.022 x 10^23 particles of N / 1 mol N)
= 6.21x10^21
