What is nascent hydrogen?
What is nascent hydrogen?
Nascent hydrogen is a highly reactive form of hydrogen atoms that are freshly generated, making it a stronger reducing agent than molecular hydrogen (H2).
Why is nascent hydrogen a more powerful reducing agent?
Why is nascent hydrogen a more powerful reducing agent?
Nascent hydrogen is more reactive because it exists as single, highly energized atoms, ready to donate electrons and reduce other substances. Molecular hydrogen, on the other hand, is more stable and requires more energy to break its bond, making it less reactive.

Classification of Oxides
- Oxygen reacts with metals and non-metals to form oxides
- Oxides can be acidic, alkaline, neutral, or amphoteric.
- Classify examples of oxides (NO, SO3, CaO, PbO)
- Explain the amphoteric nature of Al2O3.
- Define oxides.
Isotopes of Hydrogen
- Isotopes are different forms of an atom with the same atomic number but different atomic masses.
- Identify the isotopes of hydrogen.
- Identify the radioactive hydrogen isotope.
- List two uses of tritium.
- List one use of heavy water.
Limiting Reactant
- The amount of product formed in a chemical reaction is determined by the limiting reactant.
- Identify the limiting reactant in the given chemical reaction (CaCO3 + 2HCI → CaCl2 + H2O + CO2.)
