How would you compare the Japan Fukushima accident with what happened in Chernobyl? Some say it is of the same order.
Would you agree? Were there any major differences?
What can you say about the chemistry of the processes?
Calculate the vapor pressure of each component, the total pressure, and the composition of the vapor phase when the mole fraction of Br2 is 0.050. Assume that the conditions of an ideal dilute solution are satisfied at this concentration.
What are the equilibrium concentrations of H2,I2, and HI. (B) to what extent does the reaction proceed? Explain. (C) what is the Kc for the production of one mole HI?
The bp of the solution was 104.3C when 40 g was dissolved in 150mL of water. I lose points if I am more than 5% off. Any ideas what the actual substance might have been? Keep in mind this is a college gen chem lab.
Problem- You have 775 mL of an 0.11 M acetic acid solution. What volume (V) of 1.30 M NaOH solution must you add in order to prepare an acetate buffer of pH = 5.44? The pKa of acetic acid is 4.76.
when 2.55 g of an unknown weak monoprotic acid ha molar mass 85.0 gmol is dissolved in 250.0 g of water the freezing
how much heat is required to change a 38.6 g ice cube from ice at -14.7 deg c to water at 65 deg c?alsohow much heat is
2952 atoms of a particular isotope weight 1.1666821 x 10-18 grams. what is the identity of the isotope
Explain why acidic rain produced as a result of excess sulphur dioxide in the atmosphere can cause degradation of buidings.
Draw lewis Dot structures. Use model kits, styrofoam balls and/or gum drops to make a model of the molecule or ion. Be sure to place electron groups (toothpicks or sticks) as far apart as possible.
An air bubble initially trapped in the tip of the buret containing the standard NAOH disappears during the titration , Explain how will this affect the reported number of moles in the unknown acid
The next day you notice that some of the gas has leaked out. The pressure and temperature remain the same, but the volume has changed to 10.0 L. How many moles of gas (n2) remain in the cylinder
A certain indicator, HA, has a Ka value of 0.00050. The protonated form of the indicator is red and the ionized form is blue. What is the pKa of the indicator
