For the following reaction at equilibrium at 445 celsius the partial ressures were found to be ; [H2] = 0.45 atm, [I2] =0.10 atm and [Hi]=1.53 atm. calculate Kp for this reactino H2(g)+I2(g)---->2HI(g)
The titration involves the formation of a stable, neutral complex: Hg2+ (aq) + 2 SCN- (aq) = Hg(SCN)2 (aq) A)How many mmoles of mercury are in the sample
How many molecules of acetylene (HCCH) react with 131 molecules of oxygen to produce carbon dioxide and water
Balance the following redox equations. Identify the oxidation half reaction and the reduction half reaction.
Magnesium hydroxide, the active ingredient in milk of magnesia neutralizes stomach acid , primarily HCL, according to the reaction: Mg (OH)2 (aq) + 2 HCL(aq) ---> 2 H2 O (l) + Mg(OH)2(aq).
a solution of 1 ppm Pb2+was prepared and dispensed 1 mL of it using a volumetric transfer pipette, also the same solution was dispensed using a measuring (Mohr) pipette.
How many carbon atoms are present in the smallest ketone which cannot exhibit enol-keto tautomerism
The solubility of ammonium chloride at 70. C is 60. g of solute per 100. g of water. Which solution would be saturated at 70. C
the Fischer esterification experiment why was the majority of the ethanol boiled off prior to extraction and why was the reaction vial cooled
the 20 ml of water added to the erlenmeyer flask is to be previously boiled deionized water. Since water does absorb CO2 from the atmosphere and since CO2 dissolved in the water causes it to be slightly acidic
What is the ph of the buffer that results when 12.0 g of NaH2PO4 and 8.00 g of Na2HPO4 are diluted with water to a volume of 0.50 L? ( ka of H2PO4 = 6.2 X10-8, the molar masses of NaH2PO4 and Na2HPO4 are 120.0 g/mol and 142.0 mol respectively)
