Answer;
A decrease in the vapor pressure of the liquid.
Dissolving a solute such as potassium hydroxide in a solvent such as water results in a decrease in the vapor pressure of the liquid.
Explanation;
The vapor pressure of a liquid is the equilibrium of a vapor above its liquid.
In other words it is the pressure of the vapor resulting from the evaporation of a liquid above a given sample of the liquid in a closed container.
The vapor pressure of a liquid in a closed container depends on the temperature.
The distance between a carbon atom and an oxygen atom in the co molecule is 0.63
<h3>What is the distance?</h3>
Distance is the measurement of the farness of two objects from each other.
The distance between the molecules can be calculated by the given formula

Putting the values in the equation

Thus, the distance between a carbon atom and an oxygen atom in the co molecule is 0.63

It's an atom. It's known as the smallest particle of an element!
A flame test is an analytic procedure used in chemistry to detect the presence of certain elements. :)
Answer:
Kindly, see the attached image.
Explanation:
As clear in the attached image:
- It represents the cooling curve of water.
- It starts from 20°C, the water exists in the liquid phase.
- With time the temperature is decreased, reaching 0°C, the two phases (liquid and solid) are co-exist.
- Then, with further cooling and under 0°C reaching -20°C, all the water are exist in the solid phase (Ice).
<em>Kindly, see the attached image that clarify the cooling graph of water as it passes from 20°C to –20°C. </em>
