A scientific law is a statement based on repeated experimental observations that describes some aspects of the universe. A scientific law always applies under the same conditions, and implies that there is a causal relationship involving its elements.
Answer:
X is sodium hydroxide (caustic soda, NaOH)
y is sodium (Na)
Explanation:
The process of industrial electrolysis of sodium chloride solution by which chlorine and sodium hydroxide (caustic soda) can be produced is known as the chlor-alkali process as follows;
2NaCl + 2H₂O → Cl₂ + H₂ + 2NaOH
Given that the compound X is formed from a element y which is in the form of a pellet, we have;
The element in the above reaction that can exist as pellet is the silver white metallic sodium pellet
Therefore, the compound X is NaOH and the element y is sodium, Na.
