calculate the difference in pressure between the top and the bottom of a container exactly 84 cm deep filled at 27 degrees with water (d = 0.990 g/cm3) and copper (d=13.6 g/ cm3)?

If a reaction has g of -136kj at 110°c, will it be spontaneous at this temperature (110°c)? yes or no

Electrons are extremely important to what area of technology? a) anti-aging research b) household product development c) electronics d) drug discovery

Assuming complete dissociation of the solute, how many grams of kno3 must be added to 275 ml of water to produce a solution that freezes at -14.5 c? the freezing point for pure water is 0.0 c and k_f is equal to 1.86 c/m
