Why is water considered "sticky"? What does that mean?
dmitriy555 [2]

Answer:

Explanation:

Ya que las cargas eléctricas opuestas se atraen, las moléculas de agua tienden a atraerse unas a otras, haciendo el agua "pegajosa," como lo muestra el diagrama del lado derecho. Cuando las moléculas de agua se atraen unas a otras, se unen. Esta es la razón del porqué se forman las gotas

In the following reaction, what is the effect on the direction of the reaction if more SO3 is added to the reaction mixture?
Stolb23 [73]

Answer:

The equilibrium shifts to produce more reactants.

Explanation:

According to the Le- Chatelier principle,

At equilibrium state when stress is applied to the system, the system will behave in such a way to nullify the stress.

The equilibrium can be disturb,

By changing the concentration

By changing the volume

By changing the pressure

By changing the temperature

Consider the following chemical reaction.

Chemical reaction:

2SO₂ +  O₂  ⇄  2SO₃

In this reaction the equilibrium is disturb by increasing the concentration of Product.

When the concentration of product is increased the system will proceed in backward direction in order to regain the equilibrium. Because when product concentration is high it means reaction is not on equilibrium state. As the concentration of SO₃  increased the reaction proceed in backward direction to regain the equilibrium state and more reactant is formed.
