Reaction amounts
Substance - Amount (reacted or formed)
KClO3- - 10.0 g
KCl - 7.5 g
Al - 9.0 g
Reaction 1 ___KClO3 (s) → ___KCl (s) + ___O2 (g)
Reaction 2 ___Al (s) + ___O2 (g) → ___Al2O3 (s)
The decomposition of potassium chlorate in reaction 1 provides the necessary oxygen for reaction 2 to take place.
Determine the coefficients that will balance reactions 1 & 2. Also, find the mass of Al2O3 that will form given the amounts in the table.
A) Reaction 1: 2, 2, and 3
Reaction 2: 2, 3, and 2
7.5 grams Al2O3
B) Reaction 1: 1, 1, and 2
Reaction 2: 2, 3, and 2
9.5 grams Al2O3
C) Reaction 1: 2, 2, and 3
Reaction 2: 4, 3, and 2
11.5 grams Al2O3
D) Reaction 1: 2, 2, and 3
Reaction 2: 2, 2, and 3
16.5 grams Al2O3
