The moles of KClO₃ that were consumed is 0.343 moles
<u><em>calculation</em></u>
2KClO₃ → 2KCl +3O₂
step 1: find the moles KCl
moles = mass÷ molar mass
25.6 g÷74.55 g/mol =0.343 moles
Step 2 : use the mole ratio to determine the moles KClO₃
from equation above KClO₃ : KCl is 2:2 =1:1
therefore the moles KClO₃ = 0.343 moles
Answer:
Explanation:
‘it’s a chemical change because this may seem like a decomposition reaction because it seems like the nail is decomposing and falling apart.
C - If two people pull on it in opposite directions it stretches. Then when they let go it returns to it original size and shape
Multiply the atomic weight
