Nitrogen monoxide (NO) is a bioactive molecule in the blood. Low NO concentration cause respiratory distress and the formation of blood clots. Doctors prescribe nitroglycerin, CଷHହNଷOଽ and isoamyl nitrate, (CHଷ)ଶCHCHଶCHଶONOଶ, to increase NO. If each compound releases one molecule of NO per atom of N it contains, calculate the mass percent of NO in each.

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.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.

the objects have the same charge is correct.
