A. 2
The dash represents two electrons
Answer and Explanation:
Polar compounds are those that have an unequal sharing of electrons, causing one end to be more positively or negatively charged than the other end.
Ionic compounds are those that are made up of a positive ion and a negative ion. Clearly, we can see that if one ion is positive and the other is negative, then that would make one end of the compound more or less positively charged than the other end, which is exactly the definition of a polar compound.
That is why ionic compounds are always polar.

Answer:
The reaction will proceed left to attain equilibrium.
Explanation:
Let´s consider the following reaction.
COCl₂(g)⇄CO(g)+Cl₂(g) Kc = 2.19 × 10⁻¹⁰
To determine whether it is at equilibrium or not, we have to calculate the reaction quotient (Q).
![Q=\frac{[CO].[Cl_{2}]}{[COCl_{2}]} =\frac{3.3 \times 10^{-6} \times 6.62 \times 10^{-6} }{2.00 \times 10^{-3}} =1.09 \times 10^{-8}](https://tex.z-dn.net/?f=Q%3D%5Cfrac%7B%5BCO%5D.%5BCl_%7B2%7D%5D%7D%7B%5BCOCl_%7B2%7D%5D%7D%20%3D%5Cfrac%7B3.3%20%5Ctimes%2010%5E%7B-6%7D%20%5Ctimes%206.62%20%5Ctimes%2010%5E%7B-6%7D%20%7D%7B2.00%20%5Ctimes%2010%5E%7B-3%7D%7D%20%3D1.09%20%5Ctimes%2010%5E%7B-8%7D)
Since Q > Kc, Q has to decrease its value to achieve equilibrium. To do so, it must decrease its numerator (products) and increase its denominator (reactants). All in all, the reaction will proceed left to attain equilibrium.
