Estimate the ratio of O2 with K, O2 must be as minimum as possible over K
Analyzing the conditions
a. 170 g K, 31 g O2 → K is approximately 5x more than O2
b. 16 g K, 2.5 g O2 → K is approximately 6x more than O2
Consider the following reaction:
4K(s) + O2 (g) → 2K2O(s)
The molar mass of K is 39.09 g/mol and that of O2 is 32.00 g/mol.
Without doing any calculations, pick the conditions under which potassium is the limiting reactant
a. 170 g K, 31 g O2
b. 16 g K 2.5 g O2
c. 165 kg K 28, Kg O2
d. 1.5 g K 0.38 g O2
