Answer: The nuclide symbol of X is
Explanation:
The given nuclear reaction is a type of alpha decay process. In this process, the nucleus decays by releasing an alpha particle. The mass number of the nucleus is reduced by 4 units and atomic number is also decreased by 2 units. The particle released is a helium nucleus.
The general equation representing alpha decay process is:
For the given equation :
As the atomic number and mass number must be equal on both sides of the nuclear equation:
Thus the nuclide symbol of X is
Answer:
a. Sodium cyclopentanecarboxylate
b. No reaction
Explanation:
In this case, in the cyclopentanecarboxylic acid we have a <u>carboxylic acid</u> functional group. Therefore we have an "acid". The acids by definition have the ability to produce hydronium ions ().
With this in mind, for molecule a. we will have an <u>acid-base reaction</u>, because NaOH is a base. When we put together an acid and a base we will have as products a <u>salt and water</u>. In this case, the products are Sodium cyclopentanecarboxylate (the salt) and water.
For the second molecule, we have the hydronium ion (). This ion can not react with an acid. Because, the acid will produce the hydronium ion also, so <u>a reaction between these compounds is not possible.</u>
See figure 1
