A student carried out the electrolysis of a KI solution for a period of 15 minutes. He estimated that 8.5 X 10^-4 moles of OH- were produced.

- Write the two half reactions and the net reaction of the electrolysis

Temperature and kinetic energy are proportional. a) adirectly b) directly c) indirectly

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.

Given the following reaction: c3h8+5o2=3co2+4h20 how many grams of co2 will be produced 7 g of c3h8 and 98 g of o2
