A4,000 ml solution of agno3 contains 17.00 g of solute in water. calculate the molarity (molar concentration) of the solution.
1.) 3 x 10 -5m
2.) 3 x 10 -2m
3.) 4 x 10 -1m
4.) 1 x 10 -4m

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.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
