Work is said to be done when force moves a distance and the direction of motion is in the direction of applied force.
<h3>What is work done?</h3>
Work done is defined as the product of applied force and the distance which the applied force moves.
According to Newton's second law of motion the acceleration of a body is inversely to its mass ut directly proportional to the force and takes place in the direction of the applied force.
Therefore, work is done when force moves a distance and the direction of motion is in the direction of applied force.

Answer:
Explanation:
Sodium Chloride = Na⁺ + Cl⁻ = NaCl
Lithium bromide = Li⁺ + Br⁻ = LiBr
Magnesium fluoride = Mg ⁺² + F⁻ = Mg₂F.
Potassium Oxide = K⁺ + O⁻² = K₂O
Calcium sulphide = Ca⁺² + S⁻² = CaS
Aluminum Iodide = Al⁺³ + I⁻ = Al I₃
Barium bromide = Ba⁺² + Br⁻ = BaBr₂
Aluminum sulphide = Al⁺³ + S⁻ = Al₂S₃
Calcium Phosphide = Ca⁺² + P⁻³ = Ca₃P₂
Lithium Nitride = Li⁺ + N⁻³ = Li₃N
Magnesium Oxide = Mg⁺² + O⁻² = MgO
Aluminum Fluoride = Al⁺³ + F⁻ = AlF₃
Lithium Oxide = Li⁺ + O⁻² = Li₂O
Beryllium iodide = Be⁺² + I⁻ = BeI₂
Answer:
Both are non reactive because have complete valence shell.
Explanation:
This is sufficient
Answer:
The two would end up repelling each other very strongly and more energy would ultimately be required to keep the metal-ligand system in place
Explanation:
A complex is made up a central metal atom or ion and ligands. Ligands are lewis bases and they possess lone pairs of electrons. A complex is formed when electrons are donated from ligand species to metals.
However, if the ligand has a negative charge at a particular location and we try to put electrons from the metal near the electrons from the ligand, the two would end up repelling each other very strongly and more energy would ultimately be required to keep the metal-ligand system in place.
Answer:
The purple hockey puck; it takes a stronger force to slow down a more massive object than to speed it up.
