Chemistry
1 answer:
Stells [14]3 years ago
6 0

The correct answer is that no electrolysis occurs. This is due to the fact that pure water has no dissolved carrier ions. These ions are responsible for the current flow in water and are formed when the partial charges of water pull the ionic compounds apart and break their ionic bonds.

At 25°C and 1.0 atm, 0.84 g of a gas dissolves in 2.00 L of water. What mass of the gas dissolves
UNO [17]

The mass of the gas dissolved in 1.00 L of water at 25°C and 3.0 atm is equal to 1.26 grams.

<h3>How to determine the mass of the gas dissolved?</h3>

In order to determine the mass of the gas dissolved, we would the calculate the new (final) solubility of this gas by applying this formula:

S₁P₂ = S₂P₁

Making S₂ the subject of formula, we have:

S₂ = (S₁P₂)/P₁

S₂ = (0.42 × 3.0)/1.0

S₂ = 1.26 g/L.

Now, we can determine the mass:

Mass = solubility × volume

Mass = 1.26 × 1.00

Mass = 1.26 grams.

In the solubility lab, sugar was the _____________ and water was the _______________.
Rasek [7]

In a homogenous mixture, sugar was the solute and water was the solvent. Solubility is the maximum amount of a solute that dissolves in a given amount of solvent at a constant temperature. Solutes are more soluble in a given solvent at higher temperatures. Therefore, when temperature increases, the solubility of the solute also increases.

<span>Moreover, the solubility of the substance ranges from infinitely soluble such as alcohol in water, to poorly soluble like silver chloride in water and the species that dissolves, the solute, can be another liquid, gas or a solid.</span>

Calcium hydroxide is more soluble in water than the magnesium hydroxide .why?​
N76 [4]

Explanation:

This indicates that there are more hydroxide ions in solution than there were in the original water. This is because some magnesium hydroxide has dissolved. Calcium hydroxide solution is referred to as "lime water". A liter of pure water will dissolve about 1 gram of calcium hydroxide at room temperature.
