The theory of infinite universe and the theory of vacuum as a substance. First was disproved by the discovery of the big bang and the later by some experiments with light which have shown that vacuum is not a substance but empty space.
Answer:
C.) More NO₂ and SO₂ would form
Explanation:
Equilibrium:
This is the state of reaction in which the rate of forward reaction and reverse reaction are same.
There are three factors that effect the equilibrium condition.
The change in concentration
The change in volume
The change in temperature
In given equilibrium reaction,
SO₂ + NO₂ ⇄ NO + SO₃ + heat
when SO₃ is added it means more amount of product is on right side and equilibrium is disturb. Thus equilibrium is shifted toward the left produced more SO₂ and NO₂ and regain the equilibrium.
Answer:
''hydroxide ions make sodium hydroxide solution alkaline'' is true.
Explanation:
In the first sentence, OH+ ions is incorrect. It has to be OH- ions.
In the last sentence, hydride ions(H-ions) is incorrect. It has to be hydrogen ions(H+ ions).
<span>C. Static electricity. Except that electrons are never really at rest.</span>
Answer : The value of for the final reaction is, 184.09
Explanation :
The equilibrium reactions in aqueous solution are :
(1)
(2)
The final equilibrium reaction is :
Now we have to calculate the value of for the final reaction.
Now equation 1 is multiply by 2 and reverse the equation 2, we get the value of final equilibrium reaction and the expression of final equilibrium constant is:
Now put all the given values in this expression, we get :
Therefore, the value of for the final reaction is, 184.09
