Answer: The concentrations of A , B , and C at equilibrium are 0.1583 M, 0.2583 M, and 0.1417 M.
Explanation:
The reaction equation is as follows.
Initial : 0.3 0.4 0
Change: -x -x x
Equilbm: (0.3 - x) (0.4 - x) x
We know that, relation between standard free energy and equilibrium constant is as follows.
Putting the given values into the above formula as follows.
x = 0.1417
Hence, at equilibrium
= 0.1583 M
= 0.2583 M
Answer:
Zn(s) -> Zn2+(aq) + 2e
Explanation:
Zinc atoms = no charge
Zinc ions = +ve charge
The process of half equation for zinc is called oxidation .
(oxidation means loss of electrons)
Liquid to solid,(freezing)
Because, in solid particles only vibrate.
Answer:
25.2 grams HOAc
Explanation:
For solution preparations a simple formula for determining amount of solute needed is ...
from solid stock => grams = Molarity x Volume (Liters) x formula wt of solute
∴ grams HOAc = M·V·f.wt = (0.839M)(0.500L)(60.05g/mol) = 25.2 grams HOAc
Mixing => Transfer gram wt of solute to mixing container and dilute up to but not to exceed total needed volume.
The model of the
atom is crucial to understanding chemistry and in explaining the behavior of
matter because it will help us see what the atom is. Having knowledge of its
model will give us an idea how and why they can react to other atoms.
