Learn Turkish: Bu ülkede adalet ve eşitlik var mı? - Is there justice and equality in this country?

The -de suffix is the locative case marker, which tells us where something is located (translating to in, on, or at). Because ülke ends with a front vowel, it takes -de to mean in the country.

How is the word eşitlik (equality) formed?

It is built from the adjective eşit, which means equal. The -lik suffix is very common in Turkish for turning adjectives into abstract nouns, functioning just like the English endings -ity or -ness.

Why do we use var mı at the end of the sentence?

The word var means there is or exists. To turn a statement into a yes/no question (is there?), you add the question particle mı. A Turkish sentence typically places the location (Bu ülkede) and the subjects (adalet ve eşitlik) first, wrapping up with var mı at the very end.

Since justice and equality are two separate things, why is there no plural marker?

Unlike English, where the verb changes from is to are, the Turkish word var is actually an adjective meaning existent. It does not change form or take plural endings when you talk about multiple things. You just list the items and use a single var.
