Consider the following equilibrium:
irga5000 [103]

Consider the following equilibrium:

4NH₃ (g) + 3O₂ (g) ⇄ 2N₂ (g) + 6H₂O (g) + 1531 kJ

The given statement is True, because

According to Le Ch's Principle:

Systems that have attained the state of chemical equilibrium will tend to maintain their equilibrium state.

External factors such as the addition of products and reactants result in the disruption of the equilibrium state.

we expect the system to shift to the direction that offsets the change in concentration.

This results in the state of chemical equilibrium to be reestablished.

Hence, The statement is true,

  • The addition of more ammonia (a reactant) would offset the state of equilibrium.
  • To restore chemical equilibrium, the system must consume the excess reactants to form more products.
  • A shift to favor the products side occurs.

What is the angle between the carbon-sulfur bonds in the carbon disulfide ( cs2 ) molecule?
Bingel [31]

Answer:

180º

Explanation:

Carbon has 4 valence electrons and to complete the octet requires 4 more , so it will share with the oxigen atoms 4 more, forming a single and a pi bond similar to CO2

Since the carbon does not have lone pairs, the geometry around this central atom will be linear and the angle will be 180 ,   S = C = S

Gas particles are in constant motion, and any object in motion has kinetic energy (Ek). ... For example, in the collision of two molecules, one molecule may be deflected at a slightly higher speed and the other at a slightly lower speed, but the average kinetic energy does not change.
