15 g of a salt is dissolved in 150 mL of water, which resulted in the temperature of the water going up by 7 C. What is the energy released/absorbed by the water? (report in kJ) (include the mass of the salt in your calculation) (specific heat of water 4.18 J/gK)

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

lol idk man i guess u gotta ask bill nye the science guy
