Answer:
0.135 mole of H2.
Explanation:
We'll begin by calculating the number of mole in 3.24 g of Mg. This can be obtained as follow:
Mass of Mg = 3.24 g
Molar mass of Mg = 24 g/mol
Mole of Mg =?
Mole = mass /Molar mass
Mole of Mg = 3.24/24
Mole of Mg = 0.135 mole
Next, we shall write the balanced equation for the reaction. This is illustrated below:
Mg + 2HCl —> MgCl2 + H2
From the balanced equation above,
1 mole of Mg reacted to produce 1 mole of H2.
Finally, we shall determine the number of mole of H2 produced by reacting 3.24 g (i.e 0.135 mole) of Mg. This can be obtained as follow:
From the balanced equation above,
1 mole of Mg reacted to produce 1 mole of H2.
Therefore, 0.135 mole of Mg will also react to produce 0.135 mole of H2.
Thus, 0.135 mole of H2 can be obtained from the reaction.
The metallic bond between gold atoms makes it possible to create extremely thin sheets.
Atoms of the same element or atoms from different elements can form three types of bonds:
- Covalent bonds.
- Ionic bonds.
- Metallic bonds.
In the case of metals such as gold, the most common type of bond is the metallic bond. This bond:
- Is a strong bond.
- Involves the free movement of electrons between atoms.
- Makes metals highly malleable.
These characteristics explain the reason why it is possible to create extremely thin sheets as the material will not easily break due to the strong attraction between the atoms.
