using henderson hasselbalch calculate the ph of .5 L of 2.0M solution of nitrous acid, HNO2 that also contains 140g of nano2 (MM=70g/mol)
Weight of Water Required, Calculate the weight of water required to steam distill 500mg of bromobenzene at 95 degrees Celsius.
A compound has 2 ionizable groups, with pKas of 6.2 and 9.5. A 1.0 M solution of this compound (100 mL total volume) is found to have a pH of 6.8. A biochemist adds 60 mL of 1.0 M HCl to this solution. The solution pH is now:
The high-field:low-field integration ration is 2:1. Deduce the structure of the organic hald and explain the NMR signals. I'm thinking it's 1,1-dichloropropane.
Calculate how many whole drops (.05 mL/drop) of 6 M HCl are required to dissolve this. (I found this to be 11.59 drops
How many mL of a 0.8 M NaOH(aq) solution are required to make 500 mL of a solution with pH=12.50?
Determine how will this error control the final computed percentage of CH3COOH in the vinegar
The liquid rate used is twice the minimum, the equilibrium relationship can be represented as yA=9.95 xA then determine what is HOG, operating line relationship, NOG and packed height of the column?
A volume of 60.0mL of aqueous potassium hydroxide (KOH) was titrated against a standard solution of sulfuric acid (H2SO4). What was the molarity of the KOH solution if 24.7mL of 1.50 M H2SO4 was needed?
what quantity of heat is required to vaporize 107g of benzene, c6h6, at its boiling point, 80.1c? the heat of vaporization is +30.8kj/mol.

This acidity has affected many lakes in northern Europe, the northern United States, and Canada, reducing fish populations and affecting other parts of the ecological network within the lakes and surrounding forests
Chemical Reactions explained in this solution, 1. Some sulfuric acid is spilled on a lab bench. It can be neutralized by sprinkling sodium bicarbonate on it and then mopping up the resultant solution. The sodium bicarbonate reacts with sulfuric ac..
