Yes, an explanation/ theory for a phenomena in science is not something that is set in stone. If experiments are done that prove the current explanation is false and this is peer checked, then the explanation can absolutely be proven false.
Answer:
The reaction will shift to the left 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:
6CO₂ + 6H₂O ⇄ C₆H₁₂O₆ + 6O₂
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 O₂ increased the reaction proceed in backward direction to regain the equilibrium state and more reactant is formed.
<h3>Answer:</h3>
H₂O
Explanation:
According to Arrhenius Concept of Acid and Base, "Acid is any specie which when dissolved in water ionizes to produce H⁺ ions".
Examples:
HCl → H⁺ + Cl⁻
H₂SO₄ → 2 H⁺ + SO₄²⁻
While, "Bases are those species which when dissolved in water produces Hydroxyl Ions (OH⁻)".
Examples:
NaOH → Na⁺ + OH⁻
Mg(OH)₂ → Mg²⁺ + 2 OH⁻
Given Options:
CH₃OH:
Methanol when dissolved in water does not dissociate as follow,
CH₃OH → H₃C⁺ + OH⁻
Hence, it does not behave as Arrhenius Base.
CH₃COOH:
Acetic acid when dissolved in water produces H⁺ ions and Acetate ions i.e.
CH₃COOH → CH₃COO⁻ + H⁺
Therefore, it can act as Arrhenius Acid instead of Arrhenius Base.
H₂O:
Water when dissolved in water dissociates as,
H₂O → H⁺ + OH⁻
As it is producing both H⁺ and OH⁻ ions therefore, it can act as both Arrhenius Base and Arrhenius Acid.
H₂NNH₂:
Hydrazine when dissolved in water can neither produce OH⁻ ions nor H⁺ ions hence, it is neither Arrhenius Base nor Arrhenius Acid,
Answer:
2.52
Explanation:
C6H5COOH + H2O ⇄ C6H5COO- + H30+
0.14M 0 0
-X +X +X
---------------------------------------------------------------
0.14-X X X
Ka= 6.5 × 10^-5 = 
Since the effect of X in equation (0.14-x) is very small, it can be ignored.
x= 3.02 × 10^-3
-logx = 2.52
That is true - you have to complete the circuit for that to be done
