The correct option is: VAPORIZATION AND CONDENSATION.
Matters have the ability to change from one state to another state, this is called state transition. In the question given above, the carbon dioxide, which Uyen's was breathing out came in form of vapors and forms a cloud by condensing. Condensation is the process by which water droplets are formed when a vapor from comes in contact with cold surfaces. In the question given above, the vaporized gas condenses when it comes in contact with the humid air.
Answer:
Temperature at which molybdenum becomes superconducting is-272.25°C
Explanation:
Conductor are those hard substances which allows path of electric current through them. And super conductors are those hard substances which have resistance against the flow of electric current through them.
As given, molybdenum becomes superconducting at temperatures below 0.90 K.
Temperature in Kelvins can be converted in °C by relation:
T(°C)=273.15-T(K)
Molybdenum becomes superconducting in degrees Celsius.
T(°C)=273.15-0.90= -272.25 °C
Temperature at which molybdenum becomes superconducting is -272.25 °C
Answer:
1.6 L is the volume of NaOH that has reacted
Explanation:
The balanced reaction is:
H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O
This is a neutralization reaction between a strong acid and a strong base. The products are the correspond salt and water.
We propose this rule of three:
1 mol of sulfuric acid needs 2 mol of NaOH to react to react
Then, 2.4 moles of H₂SO₄ will react with (2.4 . 2) / 1 = 4.8 moles of NaOH
As molarity is 3M, we can determine the volume of our solution
Molarity (M) = mol / volume(L) → Volume(L) = mol / Molarity
Volume(L) = 4.8 mol / 3 M = 1.6 L
<span>the answer is
1A = 10^-10 m
so </span>1.61Å = 1.61 x 10^-10 m
he distance between the atoms of H−I is 1.61 x 10^-10 m
