Answer
Polarization is a method of restricting different plane of transverse waves into the required plane.
Polarization process is done with the help of Polaroids. Polaroids are kept at different angles, these angles are selected according to the wave requirement. Polaroids allows only waves which are aligned to it.
so, this phenomenon is the same in case of polarizing sunglasses as it restricts the unwanted sun waves to pass through it.
Velocity velocity is a vector value and needs not only the magnitude (speed) but also a direction(west)
Water breaks down into hydrogen and oxygen: It is a decomposition reaction as a single substance decomposes to give two products.

Leaves make starch using chlorophyll and carbon dioxide: Synthesis reaction: as the synthesis reaction involves two or more than two reactants which join together to result into a single main product along with the formation of simple by products.

Food burns in oxygen gas and releases a lot of energy: Combustion: Combustion process involves the use of oxygen to give products along with release of energy.

Adding vinegar (acid) to baking soda (alkali) gives a product that is neither acidic nor alkaline: Neutralization: acetic acid in vinegar reacts with soda (base) to give salt (neutral) and .
