What is the calibration factor of a calorimeter if a current of 1.20 A at a potential difference of 5.67 V raises its temperature by 1.25°C in 60.0 seconds. Calculate the energy input, using E = VIt.
What is the limiting reagent? Show the reasoning b) Calculate the theoretical yield in milliliters of the butene produced at 740 mm and 25 C when it is collected over water.R=0.0821
A gas originally occupies 20L at 24.7 psia and 5 C. What would the pressure be if the volume changed to 4.77ft3 and the temperature was 82 F? Give the answer in atmospheres.
Two volatile liquids (A and B) form an ideal mixture at 300.0K which just begins to boil at a pressure of 0.3000 atm. The vapor pressure of pure component A is 0.5000 atm and the vapor pressure of pure component B is 0.2000 atm
Limestone (CaCO3) is used to remove acidic pollutants from smokestack flue gases. It is heated to form lime (CaO), which reacts with sulfur dioxide to form calcium sulfite
vessel is filled with .202 mol of NO and .202 mol of O3 at 366K. Find the partial pressure of each produce and the total pressure in the flask at the end of the reaction.
When the gas is not flowing the pressure is the same everywhere in the pipe. How high above the bottom of the manometer would the mercury be in the am connected to the pipe?
This is for two dimensional arrays with both positive and negations ions alternating in a square pattern. I am given the hint to select an area with boundries through the middle of the outermost ions-ie the edge ions count as 1/2
If you have 60.5 g NH3, how many grams of F2 are required for complete reaction?
1 which of the following is evidence for a chemical reaction?a heating purple iodine crystals produces a purple gas.b
What is the mass in grams of 4.12 moles of CaCO3. How many moles are in 75.0g of CCl4
Presume that a pollutant enters the environment at a steady rate R as well as that, once there, its concentration decays by a first-order reaction. At long times the concentration of the pollutant turn into constant at some nonzero value.
The acid HCl is also there with the nucleophile to form the keto-enol tautomerization. An oxonium ion should form. What does the oxonium ion look like. What are the two products. Is this reaction an Sn1 or an SN2 reaction. Explain.
