You are about to dilute 2.00 mol of 100% sulfuric acid with enough water to produce a 30 mole% aqueous solution. the acid and water are initially at 25°c.

(a) how much heat would have to be removed to keep the final solution at 25°c?

(b) suppose the flask has a mass of 150 g, and that the heat capacity of the flask and its contents is 3.30 j/(g °c). if the flask is sufficiently insulated to be considered adiabatic, what will be the final solution temperature?

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
