What are the different isomers of heptane? Using the name and structural formula
Suppose we have a flask with a movable piston in which pressure is kept constant at 1.00atm. If an 8.00gram sample of solid ammonium nitrate is introduced into the flask what is the volume of the flask in liters at 298K when the ammonium nitrate h..
If 37.0 grams of hydrogen sulfide gas (H2S; MM = 34.08 g/mol) react with 37.1 grams of oxygen gas (O2, MM = 32.00 g/mol), what is the mass of sulfur dioxide (SO2, MM = 64.06 g/mol) gas produced?
In the study of a second order gas phase reaction, it was found that the molar concentration fell from 200 mmol L-1 to 80 mmol L-1 in 1.20x104 seconds. What is the rate constant of the reaction
Use the solution pH to calculate the concentration of hydronium ion present
switches sign but its magnitude is not changed. Where on the x axis (x = ____ m), is the total electric field equal to zero now?
What is the activation energy for the reaction? Give your answer to 3 significant figures.
Ever since volume is proportional to the number of moles present mole fractions of gases can be expressed as ratios of volumes at the same temperature and pressure. Compute the concentration of each gas in moles per liter at 0°C.
Explain what is the maximum amount of SO3 that can be produced by the reaction of 3.2mol of S with 6.3mol of 02 via the equation below.S (s) + O2 (g)---> SO3 (g)
identify the incorrect names of formulas.
compute the change in entropy of the universe if water vapor of one mol condenses to liquid water at the temperature of
you dissolve 0.1 mol of ammonium nitrate in 100 ml of h2o.the temperature of the solution changes from 22c to 15c.
