The mass percentage of Ba in the unknown original compound should be calculated. Concept introduction: Precipitation reaction: When two solutions are mixed together and if an insoluble compound settles down in the solution, which is known as precipitate, then the reaction is known as a precipitation reaction. The mass of the precipitate depends on the reactant masses. Mole: Mole of the compound is given by ratio between mass of the analyte and molar mass of the compound. Mole = Mass Molar mass Mass : The mass of solute present in the solution is given by multiplication of mole and molar mass of the solute. Mass = Mole × Molar mass

Interpretation Introduction

Interpretation:

The mass percentage of Ba in the unknown original compound should be calculated.

Concept introduction:

Precipitation reaction:

When two solutions are mixed together and if an insoluble compound settles down in the solution, which is known as precipitate, then the reaction is known as a precipitation reaction.

The mass of the precipitate depends on the reactant masses.

Mole:

Mole of the compound is given by ratio between mass of the analyte and molar mass of the compound.

Mole =Mass Molar mass

Mass:

The mass of solute present in the solution is given by multiplication of mole and molar mass of the solute.

Mass = Mole × Molar mass

Identifying the major species in weak acid or weak base equilibria The preparations of two aqueous solutions are described in the table below. For each solution, write the chemical formulas of the major species present at equilibrium. You can leave out water itself. Write the chemical formulas of the species that will act as acids in the 'acids' row, the formulas of the species that will act as bases in the 'bases' row, and the formulas of the species that will act as neither acids nor bases in the 'other' row.

Using reaction free energy to predict equilibrium composition Consider the following equilibrium: 2NH3 (g) = N2 (g) +3H₂ —N2 (g) AGº = 34. kJ Now suppose a reaction vessel is filled with 4.19 atm of ammonia (NH3) and 9.94 atm of nitrogen (N2) at 378. °C. Answer the following questions about this system: rise Under these conditions, will the pressure of NH 3 tend to rise or fall? ☐ x10 fall Х Is it possible to reverse this tendency by adding H₂? In other words, if you said the pressure of NH 3 will tend to rise, can that be changed to a tendency to fall by adding H₂? Similarly, if you said the pressure of NH3 will tend to fall, can that be changed to a tendency to rise by adding H₂? If you said the tendency can be reversed in the second question, calculate the minimum pressure of H₂ needed to reverse it. Round your answer to 2 significant digits. yes no atm 00. 18 Ar 무ㅎ ?
