In metallic bonding, valence electrons of metals move freely between neighbouring atoms. metals are ductile
because the forces that hold their atoms together are weak.
Explanation:
- Metallic bonds are the force which holds atoms together in a metal.
- Valence electrons present in the metals are freely moving between the other neighbouring atoms. The interaction between the positive ions which electrons leave behind and the valence electrons give the binding force which able to hold the metallic crystal together as it is.
- In metals, the electrons are free to travel from one metal to another metal. This speciality is the reason for their electric conductivity. And this shows that the metal-metal bond is weak in metal.
I want to see how the temperature of water affects the speed of rusting. What is the Independent Variable?
The Independent Variable is the temperature of water.
Answer:
Activation energy for the uncatalyzed reverse reaction = 103 kJ/mol
Explanation:
Activation energy decreases from = 56 kj/mol to 35 kj/mol
products = 78 KJ lower in energy than reactants
Activation energy for the uncatalyzed reverse reaction = 103 kJ/mol
attached below are the sketches of approximate energy-level for both catalyzed and uncatalyzed reactions
Hydroelectric energy is produced.
The purpose is to make glucose.
