What is the molarity of ZnCl2 that forms when 30.0 of zinc completely reacts with CuCl2 according to the following reaction? Assume a final volume of 285 mL . Zn+ CuCl2=ZnCl2+Cu.
Calculate the feed rate of humid air in SCMH?Vapor pressures of water at 32 °C and 4 °C are 35.7 mm Hg and 6.1 mm Hg respectively.
Sometimes redox reactions happen differently in acidic or basic solutions. Explain, in your own words, the difference in how you balance a reaction in acidic solution and basic (alkaline) solution.
an acetic acid solution of 2.87 pH is titrated with 1.5 mL of bromocresol green. When the color changes to light green, the pH is 3.95. The final color of the solution is dark blue.
2750 ml sample of 3 M Hcl solution is treated with 4.66 gm of magnesium . Calculate the concentration of the acid solution after all the metal has reacted. Assume that the volume remain unchanged-------M HCl.
