Question

Define the following terms:

1. Catalyst

2. Galvanization

3. Acid rain

4. Oxidation

5. semiconductor​

Answer 1

1. Catalyst, in chemistry, any substance that increases the rate of a reaction without itself being consumed. ... Enzymes are naturally occurring catalysts responsible for many essential biochemical reactions.
2. Galvanisation is the process of applying a protective zinc coating to iron or steel, to prevent rusting. The most common method is hot dip galvanizing, in which steel sections are submerged in a bath of molten zinc.
3. Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
4. Oxidation is the loss of electrons during a reaction by a molecule, atom or ion. Oxidation occurs when the oxidation state of a molecule, atom or ion is increased. The opposite process is called reduction, which occurs when there is a gain of electrons or the oxidation state of an atom, molecule, or ion decreases
5. Semiconductor, any of a class of crystalline solids intermediate in electrical conductivity between a conductor and an insulator. Semiconductors are employed in the manufacture of various kinds of electronic devices, including diodes, transistors, and integrated circuits.

Answer 2

Answer:

Ok I will tell you the answer

Explanation:

Catalyst :- A substance that enables a chemical reaction to proceed at a usually faster rate

Galvanization :-Galvanization is the process of applying or protective zinc coating to steel a iron

Acid rain:- A chemical rain that is Caused due to air pollution and harmful gases

Oxidation:-Oxidation is the loss of elctrons.

Semiconductor:-Semiconductor are materials which have a conductivity between conductors and non conductors
