Question

mass conserved
figure 4 iron and sulfur
react to form iron sulfide.
the masses of the reactants
and the products are shown
on the first set of scales.
the second set of scales
shows the masses of two
liquid reactants. fill in the
expected mass of the liquid
products for this second
reaction.
reading check integrate with visuals explain how
the masses on the scales in figure 4 demonstrate the law of
conservation of mass.

Explanation:

Step1: Apply the law of conservation of mass

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. So, the mass of reactants equals the mass of products.

Step2: Calculate the mass of liquid products

The mass of the first liquid reactant is \(80.5\,\text{g}\) and the mass of the second liquid reactant is \(92.8\,\text{g}\). Then the mass of products \(m = 80.5+92.8\).

$$m=173.3\,\text{g}$$

Answer:

\(173.3\,\text{g}\)
