15 grams of sodium phosphate (Na3PO4) reacts with 15 grams of ammonium nitrate (NH4NO3) . Solid ammonium phosphate ((NH4)3PO4) and sodium nitrate (NaNO3) are formed. If you performed this experiment and made 5 grams of the solid product, what is your percent yield?

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.
