If in the following diagram the substance is in the solid state during stage 1, during stage 2 the substance is boiling or condensing .
Boiling<span> is the term used to describe the rapid vaporization of a liquid. Boiling occurs when a liquid is heated to its </span>boiling<span> point.

Metallic bonding is the answer to your question.
All metals, which have metallic bonding existing in them, are malleable, which means they can be easily change shape without breaking their bonding.
To understand the reason behind this property, we have to know what a metallic bonding is. Metallic bond is the non directional electrostatic force (attraction force) existing between metal cations (atoms but with fewer electrons), and the sea of the delocalised electrons (from the atom itself). Since metallic bond is strong, and the ions are packed regularly, the structure cannot be broken easily.
Once we apply pressure to the metal, the ions adapt a new position and stays in that new shape, thus, we say metals are malleable.
Answer:
Oxygen is the oxidizing agent and accept electrons
Explanation:
- Corrosion is an example of a redox reaction which involves both reduction and oxidation process.
- During corrosion a metal loses electrons and becomes oxidized to form a metal ion. Therefore, oxygen is the oxidizing agent since it undergoes reduction by gaining electrons.
- Therefore, during corrosion of iron, iron is the reducing agent and gives electrons, while oxygen is the oxidizing agent and accepts the electrons.
The reaction formula of this is N2 + 3H2 = 2NH3. So the ratio of mol number of N2 and NH3 is 1:2. The mol number of NH3 is 2.27*2=4.54 mol. So the mass is 4.54*17=77.18 g.
