Iodine is prepared both in the laboratory and commercially by adding cl2(g) to an aqueous solution containing sodium iodide.
2 nal(aq) + cl2(g) —
i2(s) + 2 nacl(aq)
how many grams of sodium iodide, nal, must be used to produce 63.4 g of iodine, i2?

Which of two curves exhibits exponential growth

The size (radius) of an oxygen molecule is about 2.0 ×10−10m. make a rough estimate of the pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior at ordinary temperatures (t= 300k ). assume that deviatons would be noticeable when volume of the gas per molecule equals the volume of the molecule itself.
