What is tooth decay how is it caused

Adithya Dev A 5 years ago

On adding baking soda to the cake batter, it would undergo thermal decomposition due to the heat trapped in the batter. Thus, the following reaction takes place :- 2NaHCO3 (s) ----> Na2CO3 (aq) + CO2 (g) + H2O (l). The CO2 evolved makes the cake fluffy.

A type of double displacement reaction which occurs between an acidic and a basic substance where the acid nullifies effect of base and vice versa to produce neutral products like salt and water is called NEUTRALISATION REACTION. Eg:- HCl + NaOH ----> NaCl + H2O. It can occur between an acid and a base, an acid and a metallic oxide and between a non metallic oxide and a base.
When Acid and Base reacts to form Salt and Water is called Neutralization Reaction

I M Unknown 5 years ago

Take NaOh in and HCl in two different vessel..mix them ,you will get NaCl and H2O ......means salt and acid that's reaction of acid and base which results in formation of salt and water is known as neutralization rxñ

When a metal reacts with acids it produces salt , water ? and evolve hydrogen gas . This is not true for all metals Example : Mg + 2HCl → MgCl2 + H2

Abhishek Singh 5 years ago

When metal react with acid the it form Salt and hydrogen. Example= Zn + H2SO4 ---- ZnSO4 + H2 .

Anamika Yadav 5 years ago

When metal react with acid the it form Salt and hydrogen. Example= Zn + H2SO4 ---- ZnSO4 + H2 .

GENERAL FORMULA :- Metal carbonate/metal hydrogen carbonate+ acid -------->salt + carbondioxide + hydrogen. SODIUM HYDROGEN CARBONATE WITH ACID:- NaHCO3 + HCL -------> Nacl+ Co2 +H20. SODIUM CARBONATE WITH ACID:- Na2CO3 + 2HCL------> 2 Nacl + Co2 + H2O. How to test CO2 in the both cases:- Pass the evolved gas in quick lime it will turn to milky white slaked lime water.

The sun is at infinity so convex lens forms its image at second focal point which is real and very much diminished in size. While using the convex lens as burning glass, the rays of light from the sun (at infinity) are brought to focus on a piece of paper kept at the second focal plane of the lens.

Following are the important factors affecting the rate of decomposition: Litter Quality The rate of decomposition depends on the structural and chemical properties of litter. Temperature Temperature regulates the growth and activity of microorganisms. The temperature is different at different elevations. Aeration The oxygen present in the pores of the soil helps in the growth of microorganisms. Here only anaerobic microorganisms can grow and initiate decomposition. Soil pH The presence of cations and anions governs the pH of the soil, which in turn affects microbial growth. Inorganic Chemicals After decomposition, the elements like potassium, sodium, calcium, magnesium are released into the soil. Some of these are used by the microorganisms for their growth. Thus, it affects the rate of decomposition. Moisture The water present in the soil is responsible for various physiological processes of microorganisms present in the soil. .......Hope it helps.......
