The answer is A beautiful
Answer: sp2 hybridized orbital
Explanation:
The lone pair in pyridine is contained in an sp2 hybridized orbital pointing outwards from the ring. As a result, the lone pair does not contribute to the aromatic ring but still influences the properties of pyridine such as electrophilic attack. The image attached depicts the bonding in pyridine.
A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. ... Examples of large crystals include snowflakes, diamonds, and table salt.
286.8g of carbon dioxide forms when 95.6g of propane burns. The total atomic mass of the propane is 44(g). The total mass of the carbon dioxide formed when 44g of propane is burnt is 132(g). 44 divided by 44 equals 1. 132 divided by 44 equals 3. Therefore the amount of propane to carbon dioxide is in a 1:3 ratio. Therefore, 95.6 multiplied by 3 gives you the amount of carbon dioxide formed.
