Answer:
Moles of NO = 0.18
Moles of Br2 = 0.18
Explanation:
The given reaction with ICE table is:
Initial 0.64 - -
Change -2x +2x +x
Equilb (0.64-2x) 2x 2x
At equilibrium:
[NOBr] = 0.64-2x
NO = Br2 = 2x
The equilibrium moles of NOBr = 0.46
Moles of NO = Moles of Br2 = 2x = 2(0.09) = 0.18 moles
Answer: The bonds that hold molecules together break apart and form new bonds.

Answer: 2 : 1
Explanation:
Cation :
Ca - calcium = atomic number = 20
Electron dot configuration : 2, 8, 8, 2
Ca losses 2 electrons in its outermost shell and thus has a charge of 2+ in other to attain a stable octet state.
Anion:
F - has 7 valence electrons and thus needs 1 electron to achieve a stable octet state, hence it accepts one electron has has a charge of (-1)
Therefore,
Ratio of cation (+) to negative (-) = 2 :1
