The rate constants of some reactions double with every 10 degree rise in temperature. Assume that a reaction takes place at 315 K and 325 K. What must the activation energy be for the rate constant to double as described
Chlorine can be generated by heating together magnesium hypochlorite and hydrochloric acid. Magnesium chloride and water are also formed.
A wastewater treatment plant serves a population of 83, 355 people. If its primary sedimentation tank can remove 55% of the incoming solids, how much primary sludge should be produced each week
An aqueous solution was found in a bottle labelled "100. ppm Ca2+ standard." Assuming that 1) all calcium ions in the solution came from calcium carbonate (CaCO3 molar mass is 100.0 g/mol)
the osmotic pressure of this soluion was 0.00155 atm at 25 degrees celcius. calculate the molar mass of hemoglobin, which is a molecular compound and a nonelectrolyte.
Write Lewis structures, including resonance structure and formal charges if necessary
A researcher conducts an experiment to determine the work function of a palladium surface. She fires a laser with a wavelength of 254 nm at a certain time and observes electrons hitting a detector
A student in lab constructed an Ag+ sensor using the same procedure as in the Metal Ion Sensor lab that you performed. Titration of 10.00 mL of an AgNO3 solution diluted with 40.0 mL of DI water required 11.85 mL
Sulfuric acid is a component of acid rain formed when gaseous sulfur dioxide pollutant reacts with gaseous oxygen and liquid water to form aqueous sulfuric acid.
A mixture of four gases exerts a total pressure of 860 mm Hg. Gases A and B each exert 220 mm Hg. Gas C exerts 110 mm Hg. What pressure is exerted by gas D?
what concentration of Ba(OH)2 solution is left after complete precipitation of BaS. What is the mass of BaS Precipitated
A solution is prepared by mixing 75.0 mL of 5.00 M HCl and 20.0 mL of 8.00 M HNO3. Water is then added until the final volume is 1.00 L. Calculate [H+], [OH -], and the pH for this solution.
To find the mass of water use the density of water = 1.0 g/mL. I have looked at multipule different solutions that have already been worked but have not been able to get the correct answer no matter how many different ways i got about getting it.
