Answer:
(a) The equilibrium partial pressure of BrCl (g) will be greater than 2.00 atm.
Explanation:
Q is the coefficient of the reaction and is calculated the same of the way of the equilibrium constant, but using the concentrations or partial pressures in any moment of the reaction, so, for the reaction given:
Q = (pBrCl)²/(pBr₂*pCl₂)
Q = 2²/(1x1)
Q = 4
As Q < Kp, the reaction didn't reach the equilibrium, and the value must increase. As we can notice by the equation, Q is directly proportional to the partial pressure of BrCl, so it must increase, and be greater than 2.00 atm in the equilibrium.
The partial pressures of Br₂ and Cl₂ must decrease, so they will be smaller than 1.00 atm. And the total pressure must not change because of the stoichiometry of the reaction: there are 2 moles of the gas reactants for 2 moles of the gas products.
Because is a reversible reaction, it will not go to completion, it will reach an equilibrium, and as discussed above, the partial pressures will change.
The answer is
You must make sure each reactant has the same amount of subscripts on both sides of the equation.
Answer:
The purpose of cryolite during electrolysis is that the mixture of cryolite and aluminium oxide has a lower melting point than pure aluminium oxide. Molten cryolite serves as a solvent for the molten aluminium oxide and increases the conductivity of the solution.
Solids— have tightly packed molecules, structured shape
Liquid— have no definite shape and the molecules are not tightly packed like a solid, they are a lot more loose.
Gas— No structure at all, molecules are free flowing
Sorry I couldn’t be a better help.. but I hope this gives you a bit of an idea :)
Acetylene has a chemical formula which can be written as:
C2H2
We can see that there are two positive ions, H+. Now what
deprotonation means is that the H+ is removed from acetylene to form acetylene
ion and water. In this case, I believe that the answer would be:
