-1.09'C is the change in freezing point
“Freezing point depression” depends on the solvent and the molar concentration of the solute.
Sulfide is highly basic, consequently
K2S
completely and irreversibly hydrolyzes in water according to the following equation:
K2S+H2O→KOH+KSH
<h3>What is freezing?</h3>
Freezing, also known as solidification, is a phase transition where a liquid turns into a solid when its temperature is lowered below its freezing point.
the temperature at which a liquid solidifies specifically : the temperature at which the liquid and solid states of the substance are in equilibrium at atmospheric pressure : melting point the freezing point of water is 0° Celsius or 32° Fahrenheit.

It is a radio wave
Explanation:
The energy of an electromagnetic waves is related to its frequency by the equation:
where
h is the Planck constant
f is the frequency of the wave
We notice that the energy of an electromagnetic wave is proportional to its frequency. This means that waves with higher frequencies, such as gamma rays, x-rays, are more energetic, while waves with lower frequencies, such as microwave and radio waves, are the less energetic.
In this case, we want to find the frequency of a wave with energy
E = 0.000001 eV
Converting into Joules,
Solving for the frequency,
Which falls in the range of frequency of radio waves.

Answer:
i dont think so
Explanation:
is there a image to explain this ? if so it would help ALOT
Scientists make hypothesis, or an educated guess. And they test there "guess" and see if there right or wrong. And they learn from there guess.
I hope this answer helped u
