A NC Coastal Plain organic soil has a pH of 4.5 and a CEC = 30 meq/100g. What lime rate would you recommend? A dealer sells 80% CCE lime with the following characteristics: 50% < 60 mesh; 30% < 8-60 mesh; 20% > 8 mesh. How much lime material would you apply?
How is it possible for temperatures below the ice to be actually warmer than surface temperatures
A careless student, Will Bobble, misread the label on a bottle of 10 M sodium hydroxide and used it (rather than 1 M NaOH) to dissolve his vanillin. Then he stored the solution and left the lab early to catch a ride home. During the next lab perio..
a 112.2510g irregularly shaped object is placed in a graduated cylinder that contains 25.0 cm cubed of water. What is the solids density if the new water level was 37.5 cm cubed
Describe how you will prepare the 1.00 x 10-3 M phosphate solution using the phosphate stock solution provided (1.00 x 10-1 M) to create a 200 mL of 1.00 x 10-3 M phosphate solution.
methyl amine (CH3NH2 Kb= 3.6x10^-4) with 25.0 mL OF 0.10 M benzoic acid (C6H5COOH Ka = 6.3x10^-5), will the resulting solution be acidic, basic, or neutral?
Write the structure of a different product that could have been formed if you used ethanol containing substantial amount of water instead of the absolute ethanol
Aqueous solutions of each of the following salts {sodium acetate, sodium phosphate, sodium formate, and sodium carbonate} have a pH that is > 7. The reason for this is that the anion undergoes a so-called "hydrolysis reaction".
Bromine can form compounds or ions with any number of fluorine atoms from one to five. Write the formulas of all five of these species
A water skier is pulled by a net force of 135 N and has an acceleration of 1.8 m/s2. What is the mass of the skier.
Suppose that coal of density 1.5 g/cm3 is pure carbon. (It is, in fact, much more complicated, but this is a reasonable first approximation.)
when separated from a water solution CuSO4 forms a hydrate with 5 wlater molecules per formula unit. if 47 g of anhydrous CuSO4 are dissolved in water, what mass of the hydrate could be recovered from the solution.
Calculate the volume occupied by 1.00 mol N2 using the van der Waals equation in the form of a virial expansion at (a) its critical temperature, (b) its Boyle temperature,
