When you mix sodium carbonate and HCl, two molecules of HCl give their hydrogen atoms to the sodium carbonate. This produces carbonic acid, with the formula H2CO3. The sodium from sodium carbonate forms a salt with the chloride particles from the HCl, producing sodium chloride, or table salt.

Sodium carbonate is either found naturally or is manufactured from sodium chloride (common salt). It has many uses, notably to make glass.

A simple demonstration of how a precipitate is evidence of a chemical reaction taking place is performed by mixing solutions of calcium chloride and sodium carbonate to form the precipitate calcium carbonate (CaCO3).

We will study a reaction in which a precipitate is formed. The reaction is: Na2CO3 (aq) + CaCl2(aq) → CaCO3 (s) + 2 NaCl (aq) We will use approximately 0.02 mole of each reactant and expect to obtain approximately 0.02 mole of solid product, since the stoichiometric coefficients are all 1 in the balanced equation.

Type of Chemical Reaction: For this reaction we have a double replacement reaction. Balancing Strategies: This is a double replacement (displacement) reaction. You only need to change one coefficient to balance this equation. The CaCO3 might be a good place to start.

Calcium chloride, CaCl2 , a soluble ionic compound, and sodium carbonate, Na2CO3 , also a soluble ionic compound, will react to form calcium carbonate, CaCO3 , an insoluble solid that precipitates out of solution, and sodium chloride, another soluble ionic compound.

Sodium is a chemical element with the symbol Na (from Latin natrium) and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table….

Reaction of sodium with bases Sodium metal reacts rapidly with water to form a colourless basic solution of sodium hydroxide (NaOH) and hydrogen gas (H2). The reaction continues even when the solution becomes basic. The resulting solution is basic because of the dissolved hydroxide. The reaction is exothermic.

exothermic reaction

Na melts on water as a blood cell that slides over the water surface. The reaction with heavier elements is extremely violent producing explosions due to contact of hydrogen with oxygen from the air.

The best and only recommended way to extinguish a Class D fire is to use a dry powder fire extinguisher. This works by smothering the fire, and therefore the oxygen within it, and also absorbing the heat contained within the fire, eventually leading to its extinction.

In ordinary air, sodium metal reacts to form a sodium hydroxide film, which can rapidly absorb carbon dioxide from the air, forming sodium bicarbonate. The temperature of burning sodium increases rapidly to more than 800 °C (1,500 °F), and under these conditions the fire is extremely difficult to extinguish.

Sodium reacts with the oxygen in air to form an oxide called the sodium oxide, and traces of yellow sodium peroxide. Therefore, the sodium metal should be immersed in kerosene oil, if it is kept open it reacts vigorously with oxygen and the moisture that is already present in the air and thus catches fire.

Sodium is a very reactive metal, it tends to react with oxygen to form sodium oxide but this is an unstable compound and soon reacts with hydrogen to form sodium hydroxide. Sodium is the metal reacts vigorously with oxygen and water. 4 Na + O2 → 2 Na2O.

Sodium is a very high reactive metal. when is it kept in open sodium reacts with oxygen in the air at room temperature, to form, sodium oxide. Therefore it catches fire and starts burning when kept in open in the air.

Complete combustion needs a plentiful supply of air so that the elements in the fuel react fully with oxygen.. So,when sodium was heated and put into jar full of oxygen it generates a lot of heat energy and light.. So it’s complete combustion..

Small pieces of sodium burn in air with often little more than an orange glow. Using larger amounts of sodium or burning it in oxygen gives a strong orange flame. You get a white solid mixture of sodium oxide and sodium peroxide.

Oxygen

When you light a candle a combustion reaction takes place with the wax of the candle which is the fuel and the air which contains oxygen. The flames are the are in which this combustion reaction is taking place. The release of heat and light energy from this exothermic reaction happens through the flame.

Coal does not burn with flame, But candle burns with flame. when we blow air to coal it starts burning, But candle stop burning if we blow air to it. Burning of coal is chemical change while burning of candle is physical as well as chemical change.

Air contains about 21 percent oxygen, and most fires require at least 16 percent oxygen content to burn. Oxygen supports the chemical processes that occur during fire. When fuel burns, it reacts with oxygen from the surrounding air, releasing heat and generating combustion products (gases, smoke, embers, etc.).

The substances which vapourise during burning, give flames. For example, kerosene oil and molten wax rise through the wick and are vapourised during burning and form flames. Charcoal, on the other hand, does not vapourise and so does not produce a flame.
