All of the above so it would be c
Answer:
12.4 g
Explanation:
Let's consider the following balanced equation.
H₂O₂(aq) → H₂O(l) + 0.5 O₂(g)
The molar ratio of H₂O₂ to O₂ is 1:0.5. The moles of H₂O₂ required to form 0.182 moles of O₂ are:
0.182 mol O₂ × (1 mol H₂O₂/ 0.5 mol O₂) = 0.364 mol H₂O₂
The molar mass of H₂O₂ is 34.01 g/mol. The mass of H₂O₂ corresponding to 0.364 moles is:
0.364 mol × 34.01 g/mol = 12.4 g
Answer:
It's because they aren't destroyed they're just rearranged differently to create different products. There's like a name for this. It's something like the law of conservation energy. But the reason is mass cannot be created nor can it be destroyed.
