<h2>Question:</h2>
- A solution that is able to dissolve additional solute is best described as _____.
<h2>Answer:</h2>
<h2>D.) Unsaturated </h2>
- <u>Unsaturated</u> means the substance is poured into the solvent that can be dissolved. It is a solution (with less solute than the saturated solution) that completely dissolves, leaving with no remaining substances.
<h2>For example:</h2>
- If you were to pour olive oil into a glass of water, it will dissolve, so it is <u>unsaturated</u>.

Answer:
- 0.99 °C ≅ - 1.0 °C.
Explanation:
- We can solve this problem using the relation:
<em>ΔTf = (Kf)(m),</em>
where, ΔTf is the depression in the freezing point.
Kf is the molal freezing point depression constant of water = -1.86 °C/m,
m is the molality of the solution (m = moles of solute / kg of solvent = (23.5 g / 180.156 g/mol)/(0.245 kg) = 0.53 m.
<em>∴ ΔTf = (Kf)(m)</em> = (-1.86 °C/m)(0.53 m) =<em> - 0.99 °C ≅ - 1.0 °C.</em>
Answer: a, b, d
Explanation:Physical property are measurable (or perceived) property of something observable without having to change the composition or identity of that thing.
Examples of physical properties in the context included in the question are the following: • Temperature • Solubility • Resistivity • Conductivity • Density
Explanation:
The reaction of potassium carbonate with hydrochloric acid is as follow -
Potassium Carbonate + Hydrochloric acid → Potassium Chloride + Water + Carbon Dioxide.
In the above reaction , the metal carbonate reacts with an acid to give salt , water and carbon dioxide .
The reaction is an exothermic reaction , as the release of carbon dioxide , is indicated by vigorous effervescence .
Hence ,
The temperature of the reaction increases a lot and hence the reaction is very dangerous .
Therefore , the reaction is very risky to perform.
