Question

examine the data for each of the following reaction experiments and answer the questions based on analysis of the data. experiment #1 magnesium + oxygen -----> magnesium oxide 48.6g mg + 32.0g o₂ -----> 80.6g mgo a. what is the mass of each reactant? b. what is the mass of the product? c. what is the total mass of reactants? d. does this experimental data support the law of conservation of mass? explain.

Explanation:

Step1: Identify reactant masses

The mass of magnesium ($Mg$) reactant is $48.6g$ and the mass of oxygen ($O_2$) reactant is $32.0g$.

Step2: Identify product mass

The mass of the product magnesium - oxide ($MgO$) is $80.6g$.

Step3: Calculate total reactant mass

Add the masses of the reactants: $48.6g+32.0g = 80.6g$.

Step4: Check law of conservation of mass

The law of conservation of mass states that the total mass of reactants equals the total mass of products in a chemical reaction. Here, the total mass of reactants ($80.6g$) is equal to the mass of the product ($80.6g$).

Answer:

a. Mass of $Mg$ reactant: $48.6g$, Mass of $O_2$ reactant: $32.0g$
b. Mass of product: $80.6g$
c. Total mass of reactants: $80.6g$
d. Yes, the total mass of reactants ($48.6g + 32.0g=80.6g$) is equal to the mass of the product ($80.6g$), which supports the Law of Conservation of Mass.
