Answer:
1)4×10^13Hz
2) 9.95×10-9J
Explanation:
From the image attached, it is clear that the work function of the palladium metal must first be obtained in joules. Then, the frequency is obtained from E=hf.
The kinetic energy if the photoelectrons is obtained as the difference between the energy of the photon and the work function of the metal.
Oxygen and hydrogen share electrons in the molecule of water to form covalent bonds.
<h3>What kinds of bonds exist?</h3>
- Covalent bonds: These are formed between nonmetals and electrons by sharing electrons.
- Ionic bonds: These are formed between metals, which lose electrons, and nonmetals, which gain electrons.
- Metallic bonds: There are formed between metals. Electrons are delocalized in a cloud.
Water, H₂O, is a molecule made of 2 nonmetals: oxygen and hydrogen. The bonds that hold water molecules together are due to shared electrons, and known as covalent bonds.
Oxygen and hydrogen share electrons in the molecule of water to form covalent bonds.

Answer:
Whether you get the metal or hydrogen during electrolysis depends on the position of the metal in the reactivity series: the metal will be produced if it is less reactive than hydrogen. hydrogen will be produced if the metal is more reactive than hydrogen.
