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 characteristic of two different types of reactions are shown below. reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of and element. which statement is true about the atoms of the elements that participate in the two reactions? a: their identity changes in both reaction a and b. b: their identity changes in reaction a but not b. c: their identity changes in reaction b but not a. d: their identity remains the same.

If oil spills continue, all of the following should be expected except (2 points) death of aquatic life. polluted groundwater. decreased soil productivity. increased global temperatures.

Abeaker with 2.00×102 ml of an acetic acid buffer with a ph of 5.000 is sitting on a benchtop. the total molarity of acid and conjugate base in this buffer is 0.100 m. a student adds 4.70 ml of a 0.360 m hcl solution to the beaker. how much will the ph change? the pka of acetic acid is 4.740.
