Multiply the Kb value by the total ammonia concentration and the number 4. The total concentration is the sum of [NH4+] and [NH3] in the solution. This concentration must be known or given in order to calculate pH. For example, the concentration is equal to 0.1 molar. Then the value i...
How to calculate enthalpy of combustion Standard Enthalpy of Combustion:Standard enthalpy of combustion, {eq}\Delta H_c^{\theta} {/eq} is the enthalpy change when one mole of substance is burnt in plentiful oxygen under standard temperature and pressure....
It you know the molar concentration of an acid solution and can measure its pH, the above equivalence allows you to calculate the relative concentration of acid to conjugate base and derive the dissociation constant Ka. To do this, it helps to set up a table that delineates theInitial concen...
1. Find mole of H2, N2 and NH3 after equilibrium 2. Calculate the heat. Given that delta H = -91 kJ 3. Calculate K my solution : 3H2 + N2 ---> 2NH3 I 3 9 C -3x -x +2x E 3-3x 9-x 2x then 2x/(2x+12−3x−x) = 1/2 then x = 2 but it's impossible because ...

A sample of liquid NH3 is brought to its boiling point. Which of the following occurs during the boiling process? A. The N-H bonds within the NH3 molecules break apart. B. The overall temperature of the solution rises as the NH3 molecules speed up. C. Th How are vapor...
Ammonia, NH3, can be made by reacting nitrogen with hydrogen in the following equation: N2 + 3H2 = 2NH3 How many moles of NH3 can be made if 7.5 moles of H2 react with enough N2? Calculate the theoretical yield of NH_3, in grams, if...
