Calculate the number of milliliters of 0.544 M NaOH required to precipitate all of the Co2+ ions in 102 mL of 0.462 M CoBr2 solution as Co(OH)2. The equation for the reaction is: CoBr2(aq) + 2NaOH(aq) Co(OH)2(s) + 2NaBr(aq)

In a copper wire, a temperature increase is the result of which of the following

What is the source of continuous heat and energy that we receive from the sun

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.
