A 3 B 2 is a sparingly soluble salt of molar mass M (g m o l − 1) and solubility x g L − 1. The solubility product satisfies K S P = a ( x M ) 5 . The vlaue of a is ______(Integer answer).

Jul 29, 2015 · 74g/mol What is the heat of combustion of one gram? 35.981 kJ per gram You get 35.981 kJ when you burn one gram, and a mole is 74 grams. So wouldn't burning a mole just give you 74 times as much as burning one gram? What is 35.981 multiplied by 74?

1 mol of ferric oxalate is oxidized by x mol of M n O − 4 and 1 mol of ferrous oxalate is oxidized by y mol of M n O − 4 in acidic medium. The ratio x y is ____. View Solution

x mol N 2 O 4 is taken at P 1 atm in a closed vessel & heated. When 75 % N 2 O 4 dissociated at equilibrium, total pressure is found to be P 2 atm. The relation between P 2 & P 2 is:

1mol of H2 and 3 mol of I2 give rise at equilibrium to 1.5 mol of HI. Addition of a further 2 mol of H2 gave an additional 1.5 mol of HI. In above problem, what is K p at the temperature of the experiment.

Feb 22, 2007 · In an experiment , b mole of hydrogen iodide were put into a sealed vessel under pressure p . At equilibrium, x mole of the hydrogen iodide had dissociated , the reaction being represented by the following equation , Express in terms of b and x of Kp . Homework Equations 2HI(g) <---> H2(g) + I2(g) The Attempt at a Solution Here is my solution :

For the reaction, H 2 (g) + C O 2 (g) ⇋ C O (g) + H 2 O (g), if the initial concentration of [H 2] = [C O 2] = 1 and x mol/litre of H 2 is consumed at equilibrium, the correct expression of K p is: View Solution

Oct 25, 2008 · 3.49E-22 kJ * the Avogadro's constant, which is 6.022 × 10E23 mol-1 And I got the answer. yoohoo! Thank you so much. Please explain to me why I have to multiply my answer with the Avogadro's constant to get the final answer. I appreciate your help!

The concentration of oxalic acid is ′ X ′ mol l i t − 1. 40 m L of this solution reacts with 16 m L of 0.05 M acidified K M n O 4. What is the p H of ′ X ′ M oxalic acid solution? [Assume that oxalic acid dissociates completely.]

Mention the moles of M n O − 4 required to oxidise 1 mol of ferrous oxalate. View Solution 1 mol of ferric oxalate is oxidised by x mol of Mn{O}_{4}^{-} and also 1 mol of ferrous oxalate is oxidised by y mol of Mn{O}_{4}^{-} in acidic medium.
