The reaction between nitric oxide (NO) and oxygen to form nitrogen dioxide (NO2) is a key step in photochemical smog formation.
2 NO(g) + O2(g) 2 NO2(g)
(a) How many moles of NO2 are formed by the complete reaction of 0.324 mole of O2?
(b) How many grams of NO2 are formed by the complete reaction of 2.34 g of NO?
Draw a Lewis structure for each of the following molecules, and then use the VSEPR theory to predict the molecular deometry of each.
explain what a compound is, and give the names and formulas for 10 compounds containing your your chosen element. When 41.8 mL of 0.4731 M strontium hydroxide reacts with 26.1 mL of 0.2596 M cobalt(III) sulfate, two precipitates can form. Assume vo..
An acid solution is 0.100 M in HCl and 0.190 M in H2SO4.What volume of a 0.150 M KOH solution would have to be added to 550.0 mL of the acidic solution to neutralize completely all of the acid?
the following interactions can contribute to the intrinsic binding energy during enzymatic catalysis? Choose all that apply.- hydrogen bonding
A 2.50 mL buffer solution is .250 mol in acetic acid and .250 mol in sodium acetate. (Ka=1.8x10 to the -5). What is the initial pH to the buffer solution
A solution is prepared by dissolving 11.60 g of a mixture of sodium carbonate and sodium bicarbonate in 1.00 L of water. A 300.0- cm^3 sample of the solution is then treated with excess HNO3 and boiled to remove all the dissolved gas
A 300 L kiln is used for vitrifying ceramics. It is currently operating at 1065 degrees celsius, and the pressure is 0.9500 atm. How many moles of air molecules are within the confines of the kiln
A sample contained a mixture of ZnS and HgS. The amount of ZnS was determined by reacting 11.06 g of the sample with an excess of HCl to release H2S from each compound; ZnS(s) + 2 HCl(aq) ® ZnCl2 + H2S(g) HgS(s) + 2 HCl(aq) ® HgCl2 + H2S(g) If the..
We sometimes use complex formation to make relatively insoluble salts more soluble. For instance, AgCl(s) has Ksp=1.6x10^-10. Silver ions can form complexes with the thiosulfate ion
The amount of EDTA used for the titration was 13.49 mL. Calculate the total hardness (mg/L or ppm of calcium carbonate) for this water sample. Give your answer to one decimal place.
What is the pH of a solution that is 0.10 M CH3NH2 (methylamine) and 0.15 M methylammonium chloride
a 100.0 solution containing aqueous hcl and hbr was titrated with 0.1300 m naoh. the volume of base required to
