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
Answer:

Answer:
Ne
Explanation:
Atomic number of Ne is 10.
Electronic configuration of Ne:
Octet of Ne is complete . Element having complete octet are stable and behave ideal gas.
and 
are reactive and hence, does not behave as ideal gas.
Answer:
Heat
Explanation:
In the iron where electric current is used to heat water, electrical energy is converted to heat energy which is boils the water to steam.
Electrical energy is due to the movement of current within a circuit. The heat produced by the electrical energy is transferred to the water.
This in turn forms steam which is used for the ironing processes.
Heat energy is generated when the average kinetic energy of the molecules in a system increase.
