Explanation:
1. Only alcohols forms hydrogen bond between themselves and with other compounds containing an O-H, N-H, or F-H bond, such as water.
2. Alcohols up to 4 carbons are miscible in water because they have hydrogen bonded to oxygen and can form hydrogen bond with water. However, it is not possible for ethers.
3. When comparing ethers and alcohols of similar molecular weights, ethers have lower boiling point than alcohol. This is because of the presence of hydrogen bond in alcohols.
Answer and Explanation:
<em>Metallic bonding occurs between two or the same metals. In a metallic bonding structure, there is an electrostatic attraction between the positive metal ions leaving a sea of delocalised electrons. The sea of delocalised electrons allows metals to conduct electricity because the delocalised electrons are free to carry charge around the structure.</em>
<em>Pure metals are soft because there are layers of metal ions free to slide over each other as they are in a regular arrangement, pattern and size. </em>
<em>Alloys can be harder than pure metals because the different sizes of the atoms disturb the layers, stopping them from sliding over each other. Alloying a pure metal can let the metal become stronger and less reactive.</em>

Answer:</h3>
3.6 × 10^24 molecules
<h3>
Explanation:</h3>
Concept: Moles and Avogadro's number
- We need to know that one mole of a compound has molecules equivalent to the Avogadro's number, 6.022 × 10^23.
- Therefore; 1 mole of a compound contains 6.022 × 10^23 molecules
In this case;
We are given 6 moles of Methane;
But 1 mole of methane = 6.022 × 10^23 molecules
Therefore;
Molecules = Number of moles × Avogadro's number
= 6 moles × 6.022 × 10^23 molecules/mole
= 3.613 × 10^24 molecules
= 3.6× 10^24 molecules
Thus, there are 3.6× 10^24 molecules in 6 moles of methane.
Answer:
The answers are B and D.
Explanation:
This is because neutralisation process that contain sodium, potassium and ammonium will produce salt and water.
