Write a balanced equation for the reaction of N2 (g) with H2 (g) to produce gaseous ammonia. Determine whether the reaction will be reactant or product favored.
One of the most common causes of inaccurate melting points is too rapid heating of the melting point apparatus near Tmelt. Under these circumstances, how will the observed melting point compare to the true melting point
In a .050 M HCl solution an indicator is not all in acid form. For methyl orange, what percentage of the indicator is in each form
The Solubility of Silver Bromide at 100 Celsius degrees is 0.00037 grams for 100 grams of water. Calculate Ksp for Silver Bromide at this Temperature.
He decides to run an FTIR on the resultant powder on the cold finger apparatus. WHat functional group would clearly cofiirm that the white powder is indeed caffeine and not catechin?
can a liquid be identified by the same principl(e.g. mixing an unknown liquid with known liquid) and determining if the boiling point of the mixture is depessed if the two liquids are different?
Determine what the mothballs were made of. Pure ethyl alcohol has a boiling point of 78.41 degrees C and Kb = 1.22 deg C/m for this solvent.
What is an indicator and explain how it is used in titration. Enumerate the criteria in choosing the indicator for a specific titration.
The initial DO of the mix is 9.0 mg/L. After 5 days, the DO is 4.0 mg/L. After a long period of time, the DO is 2.0 mg/L, and it no longer seems to be dropping. Assume nitrification has been inhibited so the only BOD being measured is carbonaceous..
