An ion has a positive or negative charge. While a covalent bond always has no charge, meaning it is neutral.
Answer:
d. To the left because Q > K_p
Explanation:
Hello,
In this case, for the given reaction:

The pressure-based equilibrium expression is:

In such a way, since Kp is given we rather compute the reaction quotient at the specificed pressure of carbon dioxide as shown below:

Therefore, since Q>Kp we can see that there are more products than reactants, which means that the reaction must shift leftwards towards the reactants in order to reestablish equilibrium, thus, answer is d. To the left because Q > Kp.

Hello! Let me try to answer this :)
Thanks and please correct if there are any mistakes ^ ^
Hello!
Bromine can be classified as a pure substance.
Why?
Bromine is an element with atomic number 35 on group 17 of the Periodic Table. That's the first sign that shows us that it is a pure substance.
But the fact that it has a clear and defined boiling and melting point is a sign that we are in the presence of a pure substance. Pure substances are characterized by defined boiling and melting points.
Mixtures usually have a range of temperatures in which they melt and boil.
Have a nice day!
