How do hydrogen and oxygen atoms form covalent bonds to create water? A: Oxygen gives its electrons to hydrogen. B: Hydrogen giv
2 answers:
<u>Answer:</u> The correct answer is Option C.
<u>Explanation:</u>
Covalent bond is formed when there is sharing of electrons between the atoms that are forming a bond.
When hydrogen and oxygen form a covalent bond to form a compound named water, both the atoms share electrons with each other.
Electronic configuration of Hydrogen =
Electronic configuration of Oxygen =
As, 2 electrons are required for one oxygen atom to complete its octet and 1 electron is required by the hydrogen to have a stable configuration. Therefore, 2 atoms of hydrogen shares its electrons to 1 atom of oxygen to form water.
The chemical formula for water is .
Hence, the correct answer is option C.

Answer:
240 Nm
Explanation:
The clockwise torque is the torque determined only by the force that makes the lever rotating clockwise: therefore, the force of 80 N on the right.
The torque produced by this force is given by:
where
F is the magnitude of the force
d is the arm
For the force of 80 N on the right,
F = 80 N
d = 3 m (distance from the pivot)
So, the clockwise moment is
