Answer:

1)Sea and Land Breezes describe the wind that blows onshore from sea to land during the day and blows offshore in the evening.

2)An acid–base reaction is a chemical reaction that occurs between an acid and a base. It can be used to determine pH

In chemistry, there are three definitions in common use of the word base, known as Arrhenius bases, Brønsted bases and Lewis bases. All definitions agree that bases are substances which react with acids as originally proposed by G.-F. Rouelle in the mid-18th century.

example of acids- Hydrochloric acid ,Sodium hydroxide sulfuric acid

example of bases-Drain cleaner.

Laundry detergent.

Lubricating grease.

Alkaline batteries

3)Carbon dioxide reacts with water to form carbonic acid (Equation 1). Carbonic acid then dissociates to give the hydrogen ion (H+) and the hydrogen carbonate ion (HCO3-) (Equation . The ability of H2CO3 to deliver H+ is what classifies this molecule as an acid, thus lowering the pH of a solution.

Nitric oxide NO: Electric discharge

Gas: Natural Sources

4)The reaction between baking soda (sodium bicarbonate) and vinegar (dilute acetic acid) generates carbon dioxide gas, which is used in chemical volcanoes and other projects

5)A single-displacement reaction, is a chemical reaction in which one element is replaced by another in a compound. It can be represented generically as: A + B-C → A-C + B This will most often occur if A is more reactive than B, thus giving a more stable product.

Explanation:

sea breeze- a breeze blowing towards the land from the sea especially during the day owing to the relative warmth of the land

land breeze - a breeze blowing towards the sea from the land especially at night owing to the relative warmth of the sea

(V) an acid is any hydrogen containing substance that is capable of donating a proton to another substance. a base is molecules or ion from an acid when this substance chemically react with acids they yield salts . bases are known to turn red litmus blue.

strong acid- hydrochloric acid , perchloric acid

strong base - potassium hydroxide, sodium hydroxide.

(VI) acid rain- acid rain is rain or any other form of precipitation that is unusually acidic meaning that it has elevated level of hydrogen ions.

equation of acid rain= HOSO2+O2<HO2+SO

(VII) the reaction between baking soda ( sodium bicarbonate) and vinegar ( dilute acetic acid ) generates carbon dioxide gas which is used in chemical volcanoes and other project this reaction is called neutralisation reaction. when these two are added co2 gas is released and effervescence is seen .

(VIII) a single displacement reaction is a chemical reaction in which one element is replaced by another in a compound
