Compute the number of grams of H2SO4 in 1 gallon of battery acid if the solution is 38.9% sulfuric acid by mass and has a density of 1.33g/mL ?
You will need to form 250 mL of 1 M sulphuric acid and distilled water then calculate How many milliliters of 2M H2SO4 and distilled water will you need?
What technology or combination of technologies would you recommend for treating the following contaminated air streams?
Are the following reactions spontaneous, non-spontaneous, or not possible?
Standard Temperature and Pressure of Chlorine, Chlorine is widely used to purify municipal water supplies and to treat swimming pool waters. Suppose that the volume of a particular sample of Cl2 gas is 8.70 L at 895 torr and 240C.
The container is then cooled to 22.5 degrees C. One now finds that the gas pressure inside the container is 0.871atm. What mass of mercury(II) oxide was originally placed into the container
At 25 degrees Celsius, .87 atm of No2(g) was allowed to decompose. At equilibrium it was found that the partial pressure of no2(g) was .81 atm. Calculate the value of kc at the temperature
Explain which of the following aqueous solutions has the strongest ion-dipole attractions:0.3 M Na3PO4, 0.1 M NiF2,0.2 M Rb2CO3, 0.01 M Sr(OH)2 , 0.03 M ScBr3.
A small hot air balloon is filled with 1.02 x 10^6 L of air (d=1.20 g/L). As the air in the balloon is heated, it expands to 1.13 x 10^6 L. What is the density of the heated air in the balloon
Consider the titration of 0.1000 M HBr with 0.1000 M KOH. Calculate the pH after 55.00 mL of the base has been added to 50.00 mL of the HBr solution
A small amount of solid AgBr was added to a 0.0100 M solution of NaBr, causing it to become saturated with AgBr. A silver electrode was placed in the solution along with a reference electrode, whose electrode potential was 0.246 V
Hydroxylamine, HONH2, readily forms salts such as hydroxylamine hydrochloride which are used as antioxidants in soaps. Hydroxylamine has Kb of 9.1 x 10^-9. What is the pH of a 0.025M HONH2 solution
Calculate the pH of a solution resulting from the titration of 50mL of 0.033M HBr with 25 mL of 0.117M KOH. Give your answer to two decimal places.
Consider a mixture of salt NaA and weak acid HA. Please derive the pH Henderson Hasselback equation by writing the equilibrium expression. Define the pKa
