The image is a model of sulfuric acid that has a chemical formula of H2SO4.
gladu [14]

Models help us to understand the properties of molecules and help us to predict the kind of reactions they undergo.

A molecular model is a three dimensional representation of a molecule. Usually, molecular models could either be;

  • Ball and stick models or
  • Space filling models.

In either case, the model gives us a vivid representation of the molecule and enables us to predict its properties and reactivity based on the the inter-connectivity of atoms in the structure as shown in the model. The model of H2SO4 as shown gives us an idea of its properties and its reactivity.

loris [4]

-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.
