This is an acid base reaction which is basically a double displacement reaction. However, since carbonic acid is produced, it rapidly decomposes to carbon dioxide and water.
Answer:
TRUE!!!!
Explanation:
Water can act as both an acid and a base in solution and undergoes autoionization, where it can be both an acid and a base to itself. When mixed with an acid, water accepts hydrogen ions and acts as a base. However, when water is mixed with a base, it donates hydrogen ions and acts like an acid.
Not my words! I hope this helps :)
Answer:
Ammonia contains an asymmetrical distribution of electric charge.
Explanation:
Hello there!
In this case, accordingly to the electronegativity difference we can calculate for the N-H bond, and based off our periodic table, which shows an electronegativity of 3.0 and 2.1 for N and H respectively, we obtain:
Which is within the range of polar molecule even the both of them are nonmetals. Thus, choices a and b are firstly discarded; nonetheless, even when they are both nonmetals, two of these elements usually have a nonpolar bond, which means that option C is discarded, and therefore, our answer is ammonia contains an asymmetrical distribution of electric charge.

Answer:
2.60 moles of A remaining.
Explanation:
According to Le Chatelier's principle, the equilibrium would shift if the volume, concentration, pressure, or temperature changes.
In this question, we were told that the volume doubles, that implies that we would have to double the molarity of B/ C (since B=C.)
However, it is obvious and clear from the given equation of the reaction that A is solid in it's activity = 1. Hence, it is then ignored.
So doubling B would be 1.30 M × 2 = 2.60 M
i.e 2.60 M moles of A was consumed.
Now; the number of moles of A remaining is 5.20 - 2.60 = 2.60 moles of A remaining.
