Need help with uncertainty. I am making a 1% sucrose solution in a 250 mL volumetric flask. First I measured out 2.5 g of sucrose on an electric balance which has an uncertainty of ± .1g. Then I put the measured out sucrose into the volumetric flask, which has an uncertainty of ± .1 mL, and filled the flask with distilled water. What would the uncertainty of the solution?

257 grams h2o i think

D. h2o + h2o > h3o + oh- confirmed.

Van der waals forces are temporary electromagnetic forces established between uncharged atoms. some neutral molecules, when close together, can become temporarily “charged,” as electrons move around the atom. water is a polar molecule, the side of the molecule that the hydrogens bond to being more positive, and the opposite side bound to the lone pairs of electrons being more negative. this means that it participates in dipole-dipole interaction (non-polar exhibits dispersion forces), and it has the capacity for hydrogen bonding.
