Answer : The figure is attached in the attachment.
Explanation : The central atom will be carbon to which at 109.8 degrees will be each chlorine atoms. And the central carbon atom is 
hybridized. There will be four chlorine atom surrounding the central carbon atom. There will be 3 lone pairs of electron on each of the chlorine atom which gets attached with carbon atom.
An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. Ionic bonds are formed between a cation, which is usually a metal, and an anion, which is usually a nonmetal. A covalent bond involves a pair of electrons being shared between atoms.
Answer: N-N: 145 pm and 167 KJ/mol
N=N: 125 pm, 418 KJ/mol
And N2: 110 pm , 942 KJ/mol
Explanation: Bond length is inversily proportional to bond energy.
Greater the bond length , smaller the bond energy and vice-versa.
Answer:
B. It is important that people are not harmed for the sake of science.
Explanation:
Ethical principles stress the need to do good and cause no harm.A researcher is therefore required to;
- obtain an informed consent from the participants
- minimize or eliminate risk of harm to participants
- protect the anonymity and confidentiality of participants
- Apply no deceptive techniques
- allow the right to withdraw from the study by a participant
I suggest watching Martin Shkerli YouTube channel. He has a ton of videos on chemistry and is very helpful.
