Question

Part 2 Which e experiment provides the strongest evidence that a new substance is formed? Din) Experiment 1, because the magnesium disappears, and bubbles form. Do Experiment 4, because the fizzing and bubbling show gas production, which is a sign of a new substance forming. Experiment 2, because the nail changes shape but remains the same substance. Din) Experiment 3, because the ice melts into water.

Answer 1

Experiment 4

Answer 2

## Step 1The question is asking us to identify which experiment provides the strongest evidence that a new substance is formed. This is a chemistry question, specifically related to chemical reactions and the formation of new substances.## Step 2Let's analyze each experiment:- Experiment 1: The magnesium disappears and bubbles form. This could indicate a chemical reaction, but it's not definitive evidence of a new substance being formed.- Experiment 2: The nail changes shape but remains the same substance. This is a physical change, not a chemical one.- Experiment 3: The ice melts into water. This is also a physical change, not a chemical one.- Experiment 4: The fizzing and bubbling show gas production, which is a sign of a new substance forming. This is a strong indication of a chemical reaction and the formation of a new substance.## Step 3Based on the analysis, Experiment 4 provides the strongest evidence that a new substance is formed.
