When the cool and hot zones of a non luminous flame’s air control valve is closed, the gas in which will be in placed as first and as it encounters air as it was in the mouth of the burner, there will be a presence of incomplete mixing, causing a combustion which would be incomplete and will also lead to a process that can’t be controlled, resulting to flame that is cool.

Consider the following equilibrium for nitrous acid, HNO2, a weak acid: HNO2(aq) + H2O (l) —><— H3O+ (aq) +NO2^-(aq) In wh
Novosadov [1.4K]

Answer:

The equilibrium will shift to the right

Explanation:

The chemical equilibrium represents a balance between direct and inverse reactions.

The Le Chatelier Principle states that variations in experimental conditions can alter this balance and displace the equilibrium position, causing more or less of the desired product to form. And in this way the system evolves in the opposite direction so as to counteract the effects of such disturbance.

The variation of one or more of the following factors are those that can alter the equilibrium condition:

  • Temperature
  • The pressure
  • The volume
  • The concentration of reactants or products

In this case:

NaOH produces OH⁻ ions. OH⁻ ion uses up H₃O⁺  through the reaction:

H₃O⁺ + OH⁻ → 2 H₂O

According to the Le Chatelier principle, the addition of NaOH consumes one of the products, decreasing its concentration. Therefore, to balance the reaction, <u><em>the equilibrium will shift to the right</em></u> in order to counteract the effect that disturbed it and recover the equilibrium state.

Which two particles are always found in equal number in neutral atoms
AysviL [449]

Answer:

When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral.

I hope it helps.

Have a great day.
