Answer to Question #68749 in General Chemistry for Mary

Question

How any grams of potassium chloride are produced if 60g of potassium chloride decompose

Answer 1

According to the law, the preservation of the masses, with 60 grams of potassium chloride, 60 grams of products are formed. And with those products, potassium chloride is formed, with the mass of potassium chloride being equal to the total mass of the substances that have reacted.
2KCl→2K+〖Cl〗_2;
m(KCl) = m(K + Cl2) = 60g;
2K+〖Cl〗_2→2KCl;
m’(KCl) = m(K + Cl2) = 60g.
Answer: 60g.
