The initial rate of a chemical reaction was measured, and one of the reactants was found to be reacting at a rate of 0.0011 mol/L s . The reaction was allowed to proceed for 15 minutes, and the rate was measured again. What would you predict about the second measured rate relative to the first? The reaction rate would be faster. The reaction rate would be slower. The reaction rate would be the same
Using a sample of ferrous ammonium sulfate hexahydrate of 0.5585 grams needs KMnO 4 solution of 21.45 ml to reach a pink endpoint then calculate what will be tha molarity of the KMnO 4 solution?
Commercial concentrated aqueous hydrogen peroxide is 30.% H2O2 by mass and has a density of 1.11 g/mL. What is the molarity of this solution
The 9.163 g their air Air Cs equals 1005J/KG c in an inflated balloon is warmed over a toaster and increases in temperature by 11°C the balloon expands against one atmospheric pressure and changes volume for one liter to two liters
if 3.80 mL of vinegar needs 45.0 mL of 0.140 M NaOH to reach equivalence point in a titration, how many grams of acetic acid are in a 1.60 qt sample of this vinegar?
The resulting W3 was transferred to 500.0 mL of 1.00 M HCl. A 100.00 mL aliquot of the HCl solution required 10.02 mL of 0.09352 M potassium permanganate (KMnO4) to reach the purple endpoint. A blank required 0.13 mL. Balance the reaction below an..
In the liver, which one of the following is part of the pathway whereby increased glucagon causes a decrease in the glycolytic pathway? activation of the fructose-2,6-bisphosphate and inhibition of phosphofructokinase-2
What volume 0.100 M NaOH will react completely with 25.00 mL of 0.100 M HCl?
Consider all the valence electron pairs of the central atom-both those that are shared in covalent bonds, called bonding pairs, and those that are unshared, called non-bonding pairs or unshared pairs.
Data for the decomposition of hydrogen peroxide at some set temperature T is include below. The rate law depends only on the concentration of H2O2.
If the metal crystallizes in a body-centered cubic structure, which choice is closest to the atomic mass?
Enough of a monoprotic acid is dissolved in water to produce a 0.0197 M. The PH of the resulting solution is 6.41. Calculate the Ka for the acid.
