X= 2.0atm when u substitute for V1P1=V2P2
The correct answer is actually
D. requires a lot of energy to become hot.
As the definition of specific heat is "the heat required to raise the temperature of the unit mass of a given substance by a given amount."
The question needs:
In a 1 M solution of N₂H₄(aq), identify the relative molar amounts of these species. from most to least...
H₂O N₂H₅⁺~OH⁻ H₃O⁺ N₂H₄
H₂O is most
second N₂H₄
N₂H₅ and OH⁻ present in equal amount
H₃O⁺ is zero
because N₂H₄ is weak base it partially ionizes in water as following:
N₂H₄ + H₂O ⇄ N₂H₅⁺ + OH⁻
Answer:
The correct answer is: Electron
Explanation:
Electron (e⁻) is the negatively charged subatomic particle that has an electric charge of -1e (−1.6022 ×10⁻¹⁹ C). It was discovered by the English physicist, Sir Joseph John Thomson (J. J. Thomson) in the year 1897 by the <em>cathode ray experiment</em>.
In the cathode ray experiment, <u>Sir Joseph John Thomson used the </u><em><u>cathode ray tubes</u></em><u> </u><u>to conclude the presence of negatively charged small subatomic particle, known as electrons, in all atoms.</u>
