Gaseous ammonia reacts with oxygen gas to produce gaseous nitrogen monoxide and liquid water. If 750 grams of ammonia and 750 grams of oxygen gas were mixed, what maximum mass of nitrogen monoxide could be produced?
A 0.0490 molal aqueous NaBr solution freezes at -0.173°C. What is its apparent percent dissociation in this solution? Kf = 1.86°C/m for water. NaBr -> Na+ + Br-
A solution of ammonia and water contains 3.00×10^25 water molecules and 5.80×10^24 ammonia molecules. How many total hydrogen atoms are in this solution?
Determine the work done by the evolution of H 2 in the subsequent reaction on the surrounding atmosphere with1atm pressure and at 25 degree celsius temperature and express your answer in Joule
If the height of the candes in the container increases at the rate of 0.270 cm/s, at what rate (kilograms per minute) does the mass of the candies in the container increase?
What is the volume of a sample of chlorine gas with a density of 0.0032 g/cm3 and a mass of 1.45 g?
Consider a glass of 171 mL of water at 29°C. Calculate the mass of ice at -15°C that must be added to cool the water to 10°C after thermal equilibrium is achieved.
Tris is widely used in a biochemical laboratory. Its acid dissociation constant is 8.32 x 10^-9. You have available at your lab bench a 0.1 M solution of Tris in its protonated form, 0.1 M solution of HCL and NaOH,
Does ammonium chloride added to water produce a simple solution, does the ammounium chloride dissociate or does a chemical reaction occur resulting in a new set of compounds.
A 0.456 gram sample of an unknown mono protic acid (let's call it HZ) was dissolved in some water (you pick the amount). Then the acidic solution was titrated to the equivalence point with 32.5 mL of 0.174 M KOH.
