Answer:
The unknown amount of potassium chloride is 13.6 grams.
Explanation:
The reaction of 14 grams of KNO₃ with KCl produces a total mass of 27.6 grams of the products.
The law of conservation of mass tells us that the total mass of the reactants must be the same that the total mass of the products. So, we can find the mass of KCl as follows:

Where <em>r</em> is for reactants and <em>p </em>is for products



Therefore, the unknown amount of potassium chloride is 13.6 grams.

Answer:
A beta particle
Explanation:
The radioactive particle must undergo a beta decay to have the mass number unchanged but the atomic number to have decreased by one.
This type of beta decay results in the emission of a positron which is a type of beta particle. It resembles an electron but it has a positive charge of 1.
