Question

1. according to the law of conservation of matter, complete the missing grams for the products.

reactants
magnesiurn (2 mg)
48 g +
oxygen (o₂)
32 g
products
magnesium oxide (2 mgo)
□ g

Explanation:

Step1: Apply the Law of Conservation of Matter

According to the law, the mass of reactants equals the mass of products.
The mass of reactants is \(48\ \text{g}+ 32\ \text{g}\).

Step2: Calculate the mass of products

$$48 + 32=80$$

Answer:

\(80\)
