1. What are heterocyclic compounds? Provide examples.
2. Lets discuss naming and structural formulas of organic alcohols.
What is the reaction order with respect to each reagent for the following reaction? Then write the rate law equation.
ammonia gas can be prepared by the following reaction caos 2 nh4ci s ---gt 2nh3g h2og caci2sif 112 g of cao and 224
The compound MgSO4 is called Epsom salts. How many grams will you need to prepare a bath containing 5.80 moles of Epsom salts? Express your answer using three significant figures.
What is the the concentration of each ion present in the solution formed by mixing 3.90 g KCl in 75.0 mL of 0.280 M CaCl2 solution. Assume that the volumes are additive
Hardness in groundwater is due to the presence of metal ions, primarily Mg2 and Ca2 . Hardness is generally reported as ppm CaCO3 or mmol/L Ca2 . To measure water hardness, a sample of groundwater is titrated with EDTA,
If you have 15mL of 0.1 M NaC2H3O2, and the pH is 7.0. What would the Kb be for this reacton
multiply this new K value for reaction 3 by the k value for reaction 2 to "add" the k values together in order to determine the K value of reaction 1.. From the K value of reaction 1, i converted it to E standard. would this be the correct way to ..
The Greek mathematician Archimedes is credited with discovering how to verify the amount of pure gold in an irregularly shaped object (e.g., a crown) by placing it in water.
Water autoionizes to produce hydronium ion and hydroxide ion. The product of the concentrations of these ions equals the water autoionization constant, Kw. This ionization constant depends on temperature, the enthalpy change, and the entropy chang..
One hundred fifty kmol of an aqueous phosphoric acid solution contains 5.00 mole % H3PO4. The solution is concentrated by adding pure phosphoric acid at a rate of 20.0 L/min
Calculate (a) the volume occupied by 8.2 mmol of the gas under these conditions and (b)an approximate value of the second virial coefficient B at 300 K.
a design secures to parts with a line of hex-head bolts whose heads have a 12 distance across the flats i.e. take a
