Answer:

165 g

Explanation:

Law of Conservation of Matter states that neither matter or energy is destroyed but instead transferred.

Since we need a total of 180 g, we need to subtract 15g of one of the products to find the missing amount:

180 g - 15 g = 165 g Cu produced

Covalent bonds usually occur between atoms that have
marta [7]

Answer: A: high ionization energies; high electron affinitlies.

Explanation: Covalent bonds are basically about sharing of electrons between two atoms to achieve that stable structure. They are formed between two atoms when both have similar tendencies to attract electrons to themselves (i.e., when both atoms have identical or fairly similar ionization energies and electron affinities). Covalent bonding usually occurs between two non-metals.

For effective and proper bonding, the two atoms involved in the covalent bonding exercise should be small and hungry for electrons. This is to enable the nuclei of both atoms to effectively attract and hold the shared electron(s) in place; hence, the need for high ionization energies & high electron affinities for a more effective covalent bonding.
