There are numerous information's of immense importance already given in the question.
Primary voltage of the transformer (V1) = 115 V
Secondary voltage of the transformer (V2) = 24 V
Number of turns in the primary (T1) = 345
Let us assume the number of turns in the secondary = T2
Then
(V1/V2) = (T1/T2)
(115/24) = 345/T2
115T2 = 345 * 24
115 T2 = 8280
T2 = 8280/115
= 72
So the correct option among all the options given in the question is option "C".
Answer:
Correct answers are B and F.
Explanation:
Inside the test tube after a certain time, the pressure inside of the test tube must be equal to the atmospheric pressure, the hydrogen displaces the water inside the tube until the pressure is the same with the atmosphere.
The hydrogen pressure inside the tube must be lower than the atmospheric pressure because otherwise the water inside it would go out until it reaches the atmosphere pressure. The atmospheric pressure is equal to the addition of the hydrogen and water pressures.
Answer:
H₂SO₄ (aq) + H₂O (l) → HSO₄⁻ (aq) + H₃O⁺ (aq)
HSO₄⁻ (aq) + H₂O (l) ⇄ SO₄⁻²(aq) + H₃O⁺ (aq) Ka
Explanation:
The sulfuric acid is a dyprotic acid.
It is a considered a strong acid but only the first deprotonation is strong.
Second deprotonation is totally weak
That's why we have equilibrium when it release the second proton.
Since a deprotonation is treated for a weak acid, the acid is considered not to completely dissociate, that's why the equilibrium
Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms, and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules.
