Question

1)What is the reaction between an acid and a base ?
Will reaction mixture become hot or cool ?

2) How crystals can be formed from crystallization method ?

3) Give chemical formula for Photosynthesis also explain briefly

4) What is milk of Magnesia ? Give Chemical name + Reaction

Answer 1

Hey there !

Thanks for the Question !

Here's the answer !

1) The reaction between an acid and a base is called as a neutralisation reaction. When an acid reacts with a base, it forms salt and water.

Reaction : Acid + Base => Salt + Water

E.g. HCl + NaOH => NaCl + H₂O

It is an exothermic reaction so heat is released which makes the mixture warm.

2) Crystallisation process is a method used for purifying impure substances by making them into their crystalline form. When a salt is mixed with water in small amount and heated in a china dish for sometime, the water inside them forms a surface around the walls of the china dish. Later on cooling the dish we get to see beautiful solid crystals of the salt added. This is how Crystals are formed in Crystallization process.

3) Photosynthesis is a process by which plant takes in Sunlight, Carbon Dioxide and water to form glucose for plants and oxygen to the environment.

Reaction = Sunlight + 6CO₂ + 6H₂0 => C₆H₁₂O₆ + 6O₂

4) Milk of magnesia is the common name of a mild base, Magnesium Hydroxide. It's chemical formula is Mg(OH)₂.

Reaction: MgO + H₂O => Mg(OH)₂

Hope my answer helped !

Answer 2

hi ✌️

1)when acid reacts with base it gives salt with water , acid base reaction is also called N̤̈ë̤ṳ̈ẗ̤r̤̈ä̤l̤̈ï̤z̤̈ä̤ẗ̤ï̤ö̤n̤̈ .

when acid is dissolved in water it give h + ions and when base is dissolved in water it give OH- ion.

Let see some examples of acid base reaction or neutralization ....

☑️ H2So4 + 2 NaOH -----> Na2So4 + 2 H2O

☑️HCL + NaOH----->NaCl + H2O

This reaction is hot because,when acid reacts with base it evolved some energy in the form of heat.
if energy is released in the form of heat then this reaction is called ë̤ẍ̤ö̤ẗ̤ḧ̤ë̤r̤̈m̤̈ï̤c̤̈ r̤̈ë̤ä̤c̤̈ẗ̤ï̤ö̤n̤̈ and if energy is observed then the reaction is called ⓔⓝⓓⓞⓣⓗⓔⓡⓜⓘⓒ ⓡⓔⓐⓒⓣⓘⓞⓝ.

2) ¢яуѕтαℓℓιzαтισи is the process of formation of large crystals in pure state from their solution .

salt is obtained by the evaporation of water .however this salt is impure and has some crystal . This salt can be converted into pure state by the process of crystallization .

it's time to do an experiment.....…….❤️❤️❤️
===============≠=========

Take a container with some water and heat it .
when water starts boiling we add some salt .Stir mixture constantly and keep on adding plain salt to it until No more of the salt can dissolve in water .

now filtered the solution .after filteration when the solution is cooled take a stick and the string to it .now put the string inside the solution .after some days we pull out the string and see large salt crystals attached together on it .
This process is called crystallization ....☝️

3)ρнσтσѕуитнєѕιѕ is the process by which plants prepare their own food using carbon dioxide and water in the presence of Sunlight .

it is the exact opposite of respiration

or,

the chemical reaction that uses sunlight to enable plants for Carbon dioxide and water into glucose and oxygen is called p̸h̸o̸t̸o̸s̸y̸n̸t̸h̸e̸s̸i̸s̸ .

now see the reaction of Pིhིoིtིoིsིyིnིtིhིeིsིiིsི :-

602 + 6 H2O ------->C6 H12 O6 + 6 O2

4)a milky white solution of magnesium hydroxide .

the chemical formula of magnesium Hydroxide is Mg (OH)2

Mg(OH)2----->Mg2+ + 2 OH-

MgO + H2O-----> Mg(OH)2
