Question

1. choose all that apply.

covalent molecules are typically found in which two states of matter at room temperature?
gas
liquid
compound
solid

1. choose the best answer.

how many electrons are shared in a triple bond?
12
6
9
3

Explanation:

• Question 6: Covalent molecules have relatively weak intermolecular forces. At room temperature, substances with covalent molecules are often in the gas (e.g., \(O_2\), \(CO_2\)) or liquid (e.g., \(H_2O\) - although water has some hydrogen - bonding which is stronger than typical covalent - molecule intermolecular forces but still relatively weak compared to ionic or metallic bonds) states. A compound is a type of substance (not a state of matter), and most covalent - bonded substances are not solids at room temperature because the weak intermolecular forces do not hold the molecules in a rigid, closely - packed structure like in ionic or metallic solids.
• Question 7: In a covalent bond, each bond is formed by sharing 2 electrons. A triple bond consists of three covalent bonds. So the number of shared electrons is \(2\times3 = 6\).

Answer:

• Question 6: gas, liquid
• Question 7: 6
