A solution contains .294 M solution sodium cyanide and .0919 M hydrocyanic acid. What is the pH of this solution.
Which of the following constants is/are needed to calculate the amount of energy required to heat 30.5g of H2O(s) at -25.0 degreeC to H20(L) at 5.0 degreeC?
dimethylpropyl p-toluenesulfonate is dissolved in acetic acid (75C), solvolysis yields five different products. Suggest reasonable structure
Sodium ions are found int eh extraellular fluid in a concentration of 150mM. How many grams per liter is this?
A solution of iodine was standardized with ascorbic acid. A 0.1150 g sample of ascorbic acid required 28.37 mL of I2 to reach a starch end point. Calculate the molarity of the iodine solution.
We have noted that water level rises to 62.4mL when a piece of metal of 48 grams is dropped into 50.0mL of H 2 O in a graduated cylinder. Determine the density of this metal?
The following data apply to 25oC and 100kPa. Assume the specific volume Vs, and Kt are constant with respect to pressure changes. delta G(graph) = 0
To account for the high electronegativity difference between hydrogen and fluorine, we reassign the orbital sites in HF in order to create an energy ladder that gives us a logical sequence for assigning electrons
What would the product be if I react crotyl chloride with NaI in acetone?
A 1.00 g sample of D2O and H2O are reacted with CL2 and HCL and DCL are produced. Then they are diluted with H2O giving a volume of 1.00L. Then 25 mL of the solution are reacted with excess AgNO3 and 0.3800g AgCl precipitate formed.
3.10 percent of the Br2 undergoes dissociation. Calculate the equilibrium constant Kc for the reaction.
Determine the intermolecular distances for the two molecules and account for their similarity or difference.
Electrolysis can be used to determine actomic masses. A current of .600 amperes deposits 2.42 grams of a certain metal from its salt solution in 1.00 hour. A second experiment shows that the dissolved salt of the metal is in a +1 oxidation state.
