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.
ANSWER
The number of moles of oxygen formed is 7.06 moles
EXPLANATION
Given that
The number of moles of mercury (II) oxide is 14.12 moles
Follow the steps below to find the number of moles of oxygen
Step 1; Write the balanced equation for the decomposition of the reaction
In the reaction above, 2 moles HgO decompose to produce 2 moles Hg and 1 mole O2
Step 2; Find the number of moles of oxygen using a stoichiometry ratio
Let x represents the number of moles of oxygen
Therefore, the number of moles of oxygen formed is 7.06 moles
