Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together.
Electrolytic cell is the type of a cell in which current drive a non-spontaneous redox reaction. Redox reactions are reactions in which the oxidation number of the reactants are changed. To change oxidation number, electrons must either be added to or removed from the reactants. However, to observe the law of conservation of mass, all the electrons removed from one reactant or atom must be added to another one, therefore, the number of species lost by one substance is equal to the number of electrons gained by the other.
Answer:
Leo is suffering from a condition known as <u><em>obsessive-compulsive disorder</em></u>.
Explanation:
The obsessive-compulsive disorder refers to an anxiety problem characterized by intrusive, recurrent and persistent thoughts that might produce worry, concern, and repetitive actions or behavior, known as <u>compulsions</u>.

The exposed example is the case of a verifying person who needs to verify everything to avoid a catastrophe. They need to check that doors are closed, or electro domestics are in their off mode.
Different colored bands in each solvent signify the different materials that are found in the substance that is been analysed.
The green band in the solvent represent the green chlorophyll which are found in leaves. Chlorophyll is the substance which gives the plants the capacity to trap energy from the sun for production of food.
