Balance the equation first:
2 KClO3 (s) ---> 2 KCl (s) + 3 O2 (g)
Moles of KClO3 = 110 / 122.5 = 0.89
Following the balanced chemical equation:
We can say moles of O2 produce =

x moles of KClO3
So, O2 = (3 / 2) x 0.89
= 1.34 moles
So, Volume at STP = nRT / P
T = <span>273.15 K
P = 1 atm
So, V = (1.34 x 0.0821 x 273.15) / 1 = 30.2 L</span>
Atomic number is less than 11
Part B question 1 Answer: C
that’s the on that makes most sense
Answer:
the last answer is right.
Answer:
3
Explanation:
remember the equation percentage yield = actual/ theoretical yield as
4.20/4.88 x 100
86.065 so 86.1.
hope this make sense:)
