Which law of chemical combination is illustrated by the fact that 168g fe reacts with 72g H2O to from 232g Fe3 O4 and 8g H2.
First of all Ambrose kee You are stupid And farheen Fatima the answer for that question is Law of Conservation of mass
Whick law of chemical combination is illustrated by the fact that 168g
The law of chemical combination that is illustrated by this scenario is the Law of Conservation of Mass. According to this law, matter cannot be created or destroyed in a chemical reaction, only rearranged.
To explain how this law is applied in this scenario, we can calculate the total mass of the reactants and compare it to the total mass of the products.
Given:
Mass of Fe (iron) = 168g
Mass of H2O (water) = 72g
We need to find:
Total mass of the reactants and total mass of the products.
Reactants:
Fe + H2O
Products:
Fe3O4 + H2
Step 1: Calculate the total mass of the reactants.
Total mass of the reactants = Mass of Fe + Mass of H2O
Total mass of the reactants = 168g + 72g
Total mass of the reactants = 240g
Step 2: Calculate the total mass of the products.
Total mass of the products = Mass of Fe3O4 + Mass of H2
Total mass of the products = 232g + 8g
Total mass of the products = 240g
Since the total mass of the reactants (240g) is equal to the total mass of the products (240g), it confirms that the Law of Conservation of Mass is being followed in this chemical reaction.
Therefore, the law being illustrated is the Law of Conservation of Mass.
