Answer:
Strong acids contain more A− than weak acids do.
Strong acids contain more H3O+ than weak acids do
Explanation:
When we talk about a strong acid, we are referring to any acid that is completely dissociated or ionized when it is in an aqueous solution.
It is very eager to lose a proton, H+ in solution according Arrhenius definition.
In aqueous solution, a strong acid ionizes as follows:
HA(aq) + H2O → H3O+(aq) + A−(aq)
Since, strong acids ionize completely in solution, strong acids contain a greater H3O+ and A− concentration than solutions of weak acids.
Answer:
D. the conversion of one element into another
Explanation:
Transmutation is the action of changing or the state of being changed into another form. Therefore, D is the correct answer choice.
<u>Answer:</u> The equilibrium constant for the given reaction is 4.224
<u>Explanation:</u>
We are given:
Equilibrium concentration of water = 0.250 M
Equilibrium concentration of hydrogen gas = 0.330 M
Equilibrium concentration of oxygen gas = 0.800 M
For the given chemical reaction:
The expression of for above reaction follows:
Putting values in above expression, we get:
Hence, the equilibrium constant for the given reaction is 4.224
