To find the mass of product 2, we can use the law of conservation of mass, which states that the total mass of the reactants must equal the total mass of the products.
The total mass of the reactants is:
\[ \text{Mass of Reactant 1} + \text{Mass of Reactant 2} = 12 \, \text{g} + 23 \, \text{g} = 35 \, \text{g} \]
Let the mass of product 2 be denoted as \( x \). According to the law of conservation of mass, we have:
\[ \text{Mass of Product 1} + \text{Mass of Product 2} = \text{Total Mass of Reactants} \]
\[ 15 \, \text{g} + x = 35 \, \text{g} \]
Now, solve for \( x \):
\[ x = 35 \, \text{g} - 15 \, \text{g} = 20 \, \text{g} \]
Thus, the mass of product 2 is **20 g**.
The total mass of the reactants is:
\[ \text{Mass of Reactant 1} + \text{Mass of Reactant 2} = 12 \, \text{g} + 23 \, \text{g} = 35 \, \text{g} \]

Thus, the mass of product 2 is **20 g**.
