If sodium metal and chlorine gas mix under the right conditions, they will form salt. The sodium loses an electron, and the chlorine gains that electron. This reaction is highly favorable because of the electrostatic attraction between the particles. In the process, a great amount of light and heat is released.

When a sodium atom transfers an electron to a chlorine atom, forming a sodium cation (Na+) and a chloride anion (Cl-), both ions have complete valence shells, and are energetically more stable. The reaction is extremely exothermic, producing a bright yellow light and a great deal of heat energy.

Dissolution of sodium chloride (table salt) in water is endothermic. This is because more energy is released upon formation of solute-solvent bonds than was required to break apart the hydrogen bonds in water, as well as the ionic bonds in KOH.

When it reacts with chlorine, the chlorine takes that electron and it is happy since it has a stable electron configuration and the sodium is happy since it has a stable electron configuration. As an ion, sodium doesn’t want to gain or lose any more electrons, so it isn’t going to react with anything, including water.

Salt water is full of sodium chloride molecules. are not poisonous and reactive like sodium metal and chlorine gas because they are electrically charged atoms called “ions.” The sodium atoms are missing their outer electron.

The hot sodium then reacts with the chlorine, producing a bright yellow light, a great deal of heat energy, and fumes of sodium chloride, which deposits on the walls of the bottle. In the first video clip, the sodium flares up almost immediately upon reaction with the water, and “burns out” quickly.

Answer: (i) Sodium (Na) is metal which is extremely reactive which reacts with water and produces hydrogen gas. H2 gas catches fire as it creates intense heat from the reaction. (iii) When sodium peroxides are dissolved in water hydrogen peroxides are formed along with the sodium hydroxide.

Metal oxides that are soluble in water dissolve in it to further form metal hydroxide. 2). Metals like potassium and sodium react violently with cold water. In case of sodium and potassium, the reaction is so violent and exothermic, that evolved hydrogen immediately catches fire…

“When sodium peroxide dissolves in water, it is hydrolyzed and forms sodium hydroxide and hydrogen peroxide.”

Sodium is a highly reactive metal and reacts vigorously with the oxygen, carbon dioxide and moisture present in the air such that it may even cause a fire. To prevent this explosive reaction, Sodium is kept immersed in kerosene because Sodium doesn’t react with kerosene.

Sodium is a very reactive metal. It is kept in kerosene to prevent it from coming in contact with oxygen and moisture. If this happens, it will react with the moisture present in air and form sodium hydroxide. This is a strongly exothermic reaction and lot of heat is generated.

Sodium

Sodium can not be stored in water because Reaction of sodium and water is highly exothermic. During this reaction hydrogen gas is produces which catches fire due to heat released during reaction. Sodum is a very-very reactive metal.

sodium is highly reactive metal and it easily and quickly reacts with water and atmospheric air. Phosphorus is also very reactive that’s why it is kept in water to prevent it from undergoing reaction with air.

Sodium is absorbed from the gastrointestinal tract, always bringing water along with it. It is the major mineral in plasma, the fluid component of blood, and in the fluids that bathe the body’s cells. Without enough sodium, all these fluids would lose their water, causing dehydration, low blood pressure, and death.

The balanced chemical equation is: 2Na+2H2​O→2NaOH+H2​. Was this answer helpful?

Sodium. When sodium is added to water, the sodium melts to form a ball that moves around on the surface. It fizzes rapidly, and the hydrogen produced may burn with an orange flame before the sodium disappears.

Why should chemical equations be balanced? Answer: According to this law, mass can neither be created nor be destroyed in a chemical reaction and obeying this law total mass of the elements or molecules present on the reactant side should be equal to the total mass of elements or molecules present on the product side.

Answer. If a chemical equation is not balanced it implies that either mass has been created or destroyed which is a contradiction to law of conversation of mass which states that matter can niether be created nor destroyed .

3 Steps for Balancing Chemical Equations

1. Write the unbalanced equation. Chemical formulas of reactants are listed on the lefthand side of the equation.
2. Balance the equation. Apply the Law of Conservation of Mass to get the same number of atoms of every element on each side of the equation.
3. Indicate the states of matter of the reactants and products.

The numbers placed in front of formulas to balance equations are called coefficients, and they multiply all the atoms in a formula. Thus, the symbol “2 NaHCO3” indicates two units of sodium bicarbonate, which contain 2 Na atoms, 2 H atoms, 2 C atoms, and 6 O atoms (2 X 3= 6, the coefficient times the subscript for O).

A fully detailed chemical equation will show the state (or phase) of matter that the atoms or molecules are in. These states are: Solid, given the symbol (s) Liquid, given the symbol (l) Aqueous, meaning dissolved in water, and given the symbol (aq)

A change in color is also another characteristic of a chemical reaction taking place. This change in color is evidence of a chemical reaction. However, one must be careful; sometimes a change in color is simply the mixing of two colors, but no real change in the composition of the substances in question.

Step 2: Count the number of atoms of each type on each side of the equation (for the reactants and for the products). If each side of the equation has the same number of atoms of a given element, that element is balanced. If all elements are balanced, the equation is balanced.
