ankoles [38]

<u>Answer:</u> Boyle's law states that gas volume is inversely proportional to pressure.

<u>Explanation:</u>

Boyle's law is one of the law used to determine the Ideal Gas equation.

This law states that pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles

Mathematically,

P\propto \frac{1}{V}          (at constant temperature and number of moles)

The above expression can also be written as:

P_1V_1=P_2V_2

where,

P_1\text{ and }V_1 are initial pressure and volume of the gas

P_2\text{ and }V_2 are final pressure and volume of the gas

Hence, Boyle's law states that gas volume is inversely proportional to pressure.

How many grams of barium sulfate, BaSO 4 , be precipitated when 2.25 moles of sodium sulfate , Na 2 SO 3 , reacts with an excess
gulaghasi [49]

Answer:

525.1 g of BaSO₄ are produced.

Explanation:

The reaction of precipitation is:

Na₂SO₄ (aq) + BaCl₂ (aq) →  BaSO₄ (s) ↓  +  2NaCl (aq)

Ratio is 1:1. So 1 mol of sodium sulfate can make precipitate 1 mol of barium sulfate.

The excersise determines that the excess is the  BaCl₂.

After the reaction goes complete and, at 100 % yield reaction, 2.25 moles of BaSO₄ are produced.

We convert the moles to mass: 2.25 mol . 233.38 g/mol = 525.1 g

The precipitation's equilibrium is:

SO₄⁻² (aq)  +  Ba²⁺ (aq)  ⇄  BaSO₄ (s) ↓       Kps
