Hypothesis Statement for Reaction 1: Magnesium Plus Hydrochloric Acid

IF a small piece of magnesium metal is added to clear hydrochloric acid, THEN gas bubbles will be produced on the surface of the magnesium, indicating a chemical reaction between magnesium and hydrochloric acid, which results in the formation of magnesium chloride and hydrogen gas.

Explanation:

  • IF: This part of the hypothesis sets up the condition of the experiment where the reactants are introduced: magnesium and hydrochloric acid.
  • THEN: This part predicts the observable result of the reaction: the formation of gas bubbles, a visual indicator of the chemical reaction taking place, and describes the expected products of the reaction, reinforcing the relationship between the reactants and products.
  • The hypothesis connects the observation (bubbles) to the underlying chemical process (the reaction producing hydrogen gas and magnesium chloride).
Answer it like your a student and short answer

IF a piece of magnesium is placed in hydrochloric acid, THEN bubbles will form on the magnesium as hydrogen gas is produced, indicating a chemical reaction has occurred.
