Answer:
Acidic solution used to clean a crucible
Explanation:
This liquid dissolves alcoholic solvents such as crucible, that is why it was selected as the ideal for cleaning.
Although it would be ideal to know in detail which chemical compound is the one you want to clean so that the cleaning technique has better effectiveness.
The answer is B. The earth's axis is tilted so that the Northern Hemisphere faces the sun. Hope this helps and good luck! :)
