Consider an iron bar on a balance as shown.
As the iron bar rusts, which of the following is true? Explain your answer.
a. The balance will read less than 75.0 g.
b. The balance will read 75.0 g.
c. The balance will read greater than 75.0 g.
d. The balance will read greater than 75.0 g, but if the bar is removed, the rust is scraped off, and the bar replaced, the balance will read 75.0 g.
Interpretation Introduction
Interpretation:
An Iron bar kept on a weighing balance is given. Rusting of the iron bar starts talking place. The given statements related to this are to be examined for being true or false.
Explanation of Solution
Given statements and analyzations:
- a. The balance will read less than
The given statement is false.
The rusting of iron takes place. Rust is produced by the reaction of iron with the atmospheric oxygen. On rusting, some of the iron gets converted to iron (III) oxide
- b. The balance will read
The given statement is false.
The rusting of iron takes place. Rust is produced by the reaction of iron with the atmospheric oxygen. On rusting, some of the iron gets converted to iron (III) oxide
- c. The balance will read greater than
