Q 1/3
Score 0
A student burns a small piece of magnesium ribbon in a closed container. After the reaction, the total mass of the container and its contents is the same as before. What does this demonstrate?
30
Mass is created during chemical reactions
Mass is destroyed during chemical reactions
Mass is conserved during chemical reactions
Atoms disappear during chemical reactions
Q 2/3
Score 0
Which balanced equation best represents the photosynthesis process, where mass is conserved?
30
CO₂ + H₂O → C₆H₁₂O₆ + O₂
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
C + O₂ → CO₂
H₂ + O₂ → H₂O
