Answer (2)
The problem states that 28.5 g of silver nitrate reacts with 16.7 g of barium sulfate.
Apply the law of conservation of mass, which states that the mass of the reactants equals the mass of the products.
Calculate the total mass of the reactants: 28.5 g + 16.7 g = 45.2 g .
The mass of the products is equal to the mass of the reactants, so the mass of the products is 45.2 g .
Explanation
Understanding the Problem We are given a chemical reaction where silver nitrate ( A g N O 3 ) reacts with barium sulfate ( B a S O 4 ) to produce some products. We are given the masses of the reactants and asked to find the mass of the products.
Applying the Law of Conservation of Mass The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. Therefore, the total mass of the reactants must equal the total mass of the products.
Calculating the Total Mass of Reactants The mass of silver nitrate is 28.5 g, and the mass of barium sulfate is 16.7 g. To find the total mass of the reactants, we add these two masses together: m re a c t an t s = m A g N O 3 + m B a S O 4 = 28.5 g + 16.7 g
Summing the Masses Performing the addition, we find the total mass of the reactants: m re a c t an t s = 28.5 g + 16.7 g = 45.2 g
Determining the Mass of Products Since the mass of the reactants equals the mass of the products, the mass of the products is also 45.2 g. m p ro d u c t s = m re a c t an t s = 45.2 g
Final Answer Therefore, the mass of the products is 45.2 g .
Examples
The law of conservation of mass is a fundamental principle in chemistry and has many practical applications. For example, in a lab setting, if you carefully measure the mass of reactants before a chemical reaction and then measure the mass of the products, you can verify that mass is conserved. This principle is also used in industrial processes to ensure that the amount of material entering a process equals the amount of material leaving the process, which is crucial for efficiency and cost control. In everyday life, understanding the conservation of mass helps us appreciate that matter doesn't simply disappear; it transforms.
The mass of the products from the reaction between silver nitrate and barium sulfate is equal to 45.2 g. This result is based on the law of conservation of mass, which states that the mass of the reactants must equal the mass of the products. Therefore, we sum the masses of silver nitrate and barium sulfate to conclude the total mass of products.
