In which process do ionic compounds separate into their oppositely charged constituent ions when they are dissolved in water?
(a) dissociation
(b) electrolyte
(c) hydration
(d) ionization

(A) dissociation

Explanation:

Dissociation in chemistry is a general process in which ionic compounds (such as salts) separate or split into smaller oppositely charged ion

While, an electrolyte is a solution that contains ions and conduct electricity.

on the other hand, Hydration is the process in which a molecule or compound is chemically  attached to water molecules.

But, ionization is the process in which a molecule acquired positive or negative charge on it.  

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
