Fizzling — Explaining Chemical Change Reaction Core Vault
Hi!
I'm Fizzling.
Welcome to Reaction Core Vault!
Will you help me investigate explaining chemical change?
The Grumblies have mixed up our clues.
Let's check the evidence!
Chemical change forms new substances, but matter is conserved.
Gases count as matter even when they are not visible.
What distinguishes a chemical change?
- A. Only a change of shape
- B. New substances
- C. Matter appearing from nothing
The answer is B: New substances
Chemical change forms new substances, but matter is conserved.
Gases count as matter even when they are not visible.
That clue helps us make sense of this place.
A closed system retains products.
If gas escapes from an open container,
the measured contents may lose mass because material left the measured system.
Why can a sealed reaction keep the same total mass?
- A. All material remains inside
- B. Gases have no mass
- C. The gas becomes massless
The answer is A: All material remains inside
Our sealed reaction model reads 100 g before and after.
A new gas is retained inside.
The stable total supports conservation, not a claim that no reaction occurred.
Hmm...
how does that connect to our first clue?
Our sealed reaction model reads 100 g before and after.
A new gas is retained inside.
The stable total supports conservation, not a claim that no reaction occurred.
What does the model read after reaction?
- A. Automatically 0 g
- B. 200 g automatically
- C. 100 g
The answer is C: 100 g
Our sealed reaction model reads 100 g before and after.
A new gas is retained inside.
The stable total supports conservation, not a claim that no reaction occurred.
Nice investigating!
