Answer 2

Solving for Equal Portions of Acid

To obtain two equal portions of 6 milliliters of acid, we can use the following approach:

1. Step 1: Fill the 7-milliliter Measuring Flask - Fill the 7-milliliter measuring flask with acid from the flask containing 12 milliliters of acid. - This leaves 5 milliliters of acid in the original flask.

2. Step 2: Transfer Acid to the 5-milliliter Measuring Flask - Pour the acid from the 7-milliliter measuring flask into the 5-milliliter measuring flask until it is full. This will leave 2 milliliters of acid in the 7-milliliter flask.

3. Step 3: Refill the 7-milliliter Measuring Flask - Refill the 7-milliliter measuring flask from the original flask containing 5 milliliters of acid.

4. Step 4: Transfer Acid to the 5-milliliter Measuring Flask Again - Pour the acid from the 7-milliliter measuring flask into the 5-milliliter measuring flask until it is full. This will leave 4 milliliters of acid in the 7-milliliter flask.

5. Step 5: Final Steps - Now, the 5-milliliter measuring flask contains 6 milliliters of acid, and the 7-milliliter measuring flask contains 4 milliliters of acid. - Pour the 6 milliliters of acid from the 5-milliliter measuring flask into a separate container. - Then, pour the remaining 4 milliliters of acid from the 7-milliliter measuring flask into the same container.

Conclusion

By following these steps, two equal portions of 6 milliliters of acid can be obtained from the original flask containing 12 milliliters of acid and the 5-milliliter and 7-milliliter measuring flasks.
