Why is IT Governance important? A situation that could have been prevented had a corporate of IT policy been in place?
Tooth enamel in mainly hydroxyapatite, Ca10(PO4)6(OH)2. If 1.117g of tooth enamel reacts with acid to give 1.111g of calcium chloride, what is the percentage of hydroxyapatite in the tooth enamel sample
Draw a formula for the lowest molecular weight compound that contains C, H, and possibly O, is a chiral compound, contains ONLY one functional group, and is a(n) alkane.
A beaker with 100 mL of an acetic acid buffer with a pH of 5.00 is sitting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100 M. A student adds 8.60 mL of a 0.380 HCl solution to the beaker. How much will the pH c..
The steel bomb of bomb calorimeter, which has a volume of 75 mL, is chaged with oxyen to a pressure of 145 atm at 22 C. Calculate the moles of oxygen in the bomb. Calculate the grams of oxygen in the bomb.
For the reaction given below, identify the anode and describe what happens to the electrode as the reaction continues.
Describe a simple and practical way to make 1.00 L of this buffer solution, assuming a 1.0 M solution of the molecular base is available and that the chloride salt of the conjugate acid is available as a solid
Using the genetic code, identify the sequence of amino acids obtained upon translation of the mRNA
Question- Here you have saturated CaF2 solution. (ksp of CaF2=3.4x10/\-11). Precipiate or dissolve into solution under the following conditions. Briefly explain why.
How many moles of alcl3 are produced from 2.75 mole of cl2
Problem- An ideal gas expands into evacuated chambers, whose walls are thermally insulated and so, cannot exchange heat with the surroundings. For the gas, define as the system,
A powder contains FeSO4·7H2O (molar mass = 278.01 g/mol) among other components. A 3.585-g sample of the powder was dissolved in HNO3 and heated to convert all iron to Fe3
What is the molar concentration of Fe2+ ion in an aqueous solution if 35.50 mL of 0.103 M KBrO3 is required for complete reaction with 11.00 mL of the Fe2+ solution? The net ionic equation is:
