Answer:

If the solution contains 35 grams of NaCl per 100 grams, the solution is unsaturated

Explanation:

Step 1: Data given

Solubility of NaCl at 20 °C = 35.89 grams NaCl per 100 grams of water

Solubility of NaCl at 30 °C = 36.09 grams NaCl per 100 grams of water

Saturated Solution: A solution with solute that dissolves until it is unable to dissolve anymore, leaving the undissolved substances at the bottom.

Unsaturated Solution: A solution (with less solute than the saturated solution) that completely dissolves, leaving no remaining substances.

Supersaturated Solution: A solution (with more solute than the saturated solution) that contains more undissolved solute than the saturated solution because of its tendency to crystallize and precipitate.

Step 2:

The solubility of NaCl at 25.0 °C: 35.89 < X < 36.09

If the solution contains 35 grams of NaCl per 100 grams, the solution is unsaturated

CH4 + 202 → CO2 + 2H2O<br> How many grams of O2 needed to produce 36 grams of H2O?

Pavel [41]

Answer:

Mass = 64 g

Explanation:

Given data:

Mass of water produced = 36 g

Mass of oxygen needed = ?

Solution:

Chemical equation:

CH₄ + 2O₂ CO₂ + 2H₂O

Number of moles of water produced:

Number of moles = mass/molar mass

Number of moles = 36 g/ 18 g/mol

Number of moles = 2 mol

Now we will compare the moles of water and oxygen.

H₂O : O₂

2 : 2

Mass of oxygen:

Mass = number of moles × molar mass

Mass = 2 mol × 32 g/mol

Mass = 64 g

If 180 grams of potassium iodide is dissolved in 100 cm3 of water at 30oC, a(n) _______________ solution is formed.

olga nikolaevna [1]

Super saturated solution is formed.

<u>Explanation:</u>

Solubility is the property of any substance's capacity, that is the solute of the substance is dissolved in the given solvent to form the solution. We have three different types of solution, unsaturated, saturated and supersaturated solution.

Unsaturated solution is a solution with lesser amount of solute than its solubility at equilibrium.

Saturated solution is a solution with the maximum solute dissolved in the solvent.

Super saturated solution is a solution with more solute than it is required.

The solubility of KI at 30°C is 153 g / 100 ml. Here 180 g of KI in 100 ml of water at 30°C is given, which has more solute than required, so it is super saturated solution.
