I would have to say it would be the closest to a gas A.
B - Evolve into the closest species on the tree’s trunk
57.1g * 6.022*10^23 / 22.9 * 2 = 7.51*10^23 molecules
Answer:
C. Br and Cl
Explanation:
The pair that will share electrons when a bond forms between them is Br and Cl.
When electrons are shared between two atoms to form a bond, then the bond type formed is called a covalent bond.
- A covalent bond forms between non-metals.
- Br and Cl are non-metals
- The electronegativity difference between the species must be very low or zero.
- This is the case for the two non-metals.
