Calculate kc for the reaction. 1.25 mol NOCI was placed in a 2.50 L reaction chamber at 427°C. After
equilibrium was reached, 1.10 moles NOCI remained. Calculate the
equilibrium constant for the reaction.
2NOCI(g) + 2NO(g) + Cl2(g)

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.

Water (2510 g ) is heated until it just begins to boil. if the water absorbs 5.09×105 j of heat in the process, what was the initial temperature of the water?
