5 0

Explanation:

In this reaction, the reactants are Li and N2. The product is Li3N

So we have;

Li + N2 → Li3N

Upon balancing, we have;

6Li + N2 → 2 Li3N

The sum of the coefficients is 6 + 1 + 2 = 9

Chloral, Cl3C―CH═O, reacts with water to form the sedative and hypnotic agent chloral hydrate, Cl3C―CH(OH)2. Draw Lewis structur
Paul [167]

Answer:

See attached figure.

Explanation:

Hello there!

In this case, according to the given substances, we recall the concept of Lewis structure as such showing the bonds and valence electrons each atom has in the molecule. Thus, since chlorine atoms have seven valence electrons, carbon atoms four of them, hydrogen atoms have 1 and oxygen atoms 6, we are able to draw such Lewis dot structures, by obeying the octet as shown on the attached figure.

Best regards!
