How does the fuel become more radioactive?

Nitrogen (n), phosphorus (p), and potassium (k) are the main nutrients in plant fertilizers. according to an industry convention, the numbers on the label refer to the mass percents of n, p2o5, and k2o, in that order. calculate the n: p: k ratio of a 30: 10: 10 fertilizer in terms of moles of each element, and express it as x: y: 1.0.

How many moles of oxygen gas are produced from the decomposition of six moles of potassium chlorate

If you burn 46.6 g of hydrogen and produce 416 g of water, how much oxygen reacted
