The reason for which the amount of gas remaining in the cylinder is determined by measuring the weight of the cylinder which is then compared with the original weight of the cylinder rather than the mass of gas from its pressure, needs to be explained. Concept introduction: The pressure exerted by a vapor in dynamic equilibrium with its liquid is called the vapor pressure. Ideal gas equation is as follows: P V = n R T Here, P is pressure, V is volume, n is number of moles, R is Universal gas constant and T is temperature of the gas.

Interpretation Introduction

Interpretation:

The reason for which the amount of gas remaining in the cylinder is determined by measuring the weight of the cylinder which is then compared with the original weight of the cylinder rather than the mass of gas from its pressure, needs to be explained.

Concept introduction:

The pressure exerted by a vapor in dynamic equilibrium with its liquid is called the vapor pressure.

Ideal gas equation is as follows:

PV=nRT

Here, P is pressure, V is volume, n is number of moles, R is Universal gas constant and T is temperature of the gas.

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 ?
