Question
Asked Nov 5, 2019

I need help with these three questions, they are all interconnected so I grouped them as one. 

2. How many moles of nitrogen are in a 2145 mL sample of the gas at 1500. torr and 120 °C?
3. Chlorine reacts with sulfite ion in the presence of water to give sulfate ion and chloride
ion How many milliliters of CI, gas measured at 25 °C and 734 torr are required to react
with all the S0,2 in 34.9 mL of 0.253 M Na, SO, solution? The chemical equation is
the following:
Cl2+ SO2+ H,O 2Cl +SO2+H*

Step 1

We’ll answer the first question since the exact one wasn’t specified. Please submit a new question specifying the one you’d like answered.

 

All matter can be classified as solid, liquid and gases mainly. In these physical states of matter, the solid state is composed of particles with least intermolecular distance and strongest intermolecular force of attraction. On the contrary, the gaseous state of matter is composed of particles with largest intermolecular distance and weakest intermolecular force of attraction. The liquid state of matter exhibits the intermediate properties of them.

 

Step 2

The gaseous state is the state of matter with least intermolecular force of attraction between molecules and highest kinetic energy. The standard properties of gases like Pressure, volume, and temperature can be calculated with the help of ideal gas equation.

Step 3

The ideal gas equation c...
