Question

How many moles of KCIO,(s) must be decomposed to yield 15 moles O2(g)?

2 KCIO,(s) 2 KCI) + 3 02(g)

Answer 1

Step-by-step explanation:

2 KCIO,(s) 2 KCI) + 3 02(g)

For every 3 moles of O2 you need 2 moles of KClO3

2/x = 3/15 Cross Multiply

3*x = 2 * 15 Combine the right

3x = 30 Divide by 3

3x/3 = 30/3 Combine

x = 10
