At constant temperature and pressure, how many liters of oxygen would be needed to completely combust 0.350 L of propane?
(balanced equation: C3H8 + 5O2 = 3CO2 + 4H2O)
Find reactant and product information, Balance the following reaction: Mn + HCl --> MnCl2 + H2, If you have 100g of Mn and 100g of HCl find
What mass of F2 is needed to produce 167 g of PF3 if the reaction has a 77.0% yield?
If iron is oxidized to Fe2+ by a copper(II) sulfate solution, and 0.538 grams of iron and 13.0 mL of 0.40M copper(II) sulfate react to form as much product as possible.
Imidazole, acting as a nucleophile, catalyzes the hydrolysis of phenyl acetate by attach on the carbonyl carbon atom of the ester. The imidazole displaces the phenoxide anion and forms acetyl imidazole
Compute the hydroxide ion concentration in a NH 3 solution that is 0.091 M and 0.028 M NH 4 Cl. Kb of NH 3 is 1.8 x 10 -5 .
calculate the heat transferred, Q when 51.0 ml of 2M NaOH solution and 50.0 ml of 2M HCl are mixed. Assume the final volume of the reaction mixture is 101.0 ml, its density is 104 g mL-1, and its heat capacity is 3.89 J g-1 deg-1
50.0 mL of 1.0 M HCl at 25.0 oC were mixed with 50.0 mL of 1.0 M NaOH also at 25.0 oC in a styrofoam cup calorimeter. After the mixing process, the thermometer reading was at 31.9 oC.
If the titrant has a molarity of 0.2750 M and there are 40.00 mL of analyte present, what is the molarity of the analyte?
Free radicals are also important in many environmentally significant reactions. For example, photochemical smog, which forms as a result of the action of sunlight on air pollutants, is formed in part by the following two steps.
a 5.00 gram sample of potassium chlorate/potassium chloride mixture was heated in a test tube. A total of 1.00 L of oxygen gas was collected over water at 25 degrees c and 741 torr. determine the percentage of potassium chlorate in the mixture.
Using a sample of 30.0 mL of Kr(g), is at 25°C and 756 mmHg. Calculate the new volume if the temperature is decreased to -125°C and pressure is decreased to 325 mmHg .
What is the pH of a solution prepared by mixing 200 ml of 0.1 M HCl with 300 ml of 0.1 M sodium acetate and diluting the mixture to 1 L?
