Answer: extremely sensitive to environmental changes caused by habitat destruction, climate change, pollution
Explanation:
Across the world, amphibians have been disappearing at an unprecedented rate — faster than any other group of animals. Frogs, toads, and salamanders are extremely sensitive to environmental changes caused by habitat destruction, climate change, pollution, and invasive species.
The reaction equation:
2H₂O + 2Na₂O₂ → 4NaOH + O₂
Moles of sodium peroxide = 10 / 78 = 0.128
Moles of oxygen released = 0.128 / 2 = 0.064 mol
Mass of oxygen = 0.064 x 32
Mass of oxygen = 2.05 grams
Answer:
C
Explanation:
Dalton's atomic theory are: Everything is composed of atoms, which are the indivisible building blocks of matter and cannot be destroyed. All atoms of an element are identical. The atoms of different elements vary in size and mass.
