The graph below shows how solubility changes with temperature.
Otrada [13]

The two solutions that have similar solubilities at 40°C will be Na₂HAsO₄ and Na₂SO₄.

<h3>What is solubity ?</h3>

It is the ability of a solute to be dissolved, especially in water.

As the temperature increases the solubility of the gas generally decreases"

According to given information and graph attached as reference ;

  • Solubility of NaCl (sodium chloride) at 40°C is 36.3 grams.
  • Solubility of Na₂SO₄ (sodium sulfate) at 40°C is 48.8 grams.
  • Solubility of Na₂HAsO₄ (sodium arsenate dibasic) at 40°C is 48.9  
    grams.
  • Solubility of Ba(NO₃)₂ (barium nitrate) at 40°C is 14.1 grams.
  • Solubility of Ce₂(SO₄)₃·9H₂O (ceasium sulfate nonahydrate) at 40°C is 6.2 grams.

Homes may be heated by pumping hot water through radiators. What mass of water will provide the same amount of heat when cooled
dolphi86 [110]

Answer:

mass of water is 7.43 g

Explanation:

q = mc∆T

qsteam = 100 g × 1.864 J/(g °C) × (110 – 100) °C = 1864 J

qwater = mwater× 4.184 J/(g °C) × (95 – 35) °C = mwater× 251.04 J/g = qsteam = 1864 J

mwater = 1864 J / 251.04 J/g = 7.43 g
