Thanks ❤️

[shinchan]

Sir please iske baad physics ka chapter electricity ka oneshot upload karo ❤

0:02 swagat hai aap sab ka science and fun pe jha teacher apko Dil or dimag dono se sikhate hai (Jo ke school Mai nahi hota was silent)😂😂

no all metals do not react with acids
Metals which are less reactive than Hydrogen do not react with acids because displacement Rxn could not take place.
ex : Cu, Ag, Pt, Au etc
35:00
No salt may be ??
its wrong ans after checking correct is it forms sodium zincate Na2ZnO2
56:25
no Rxn with base because metal oxide are already basic in nature.
1:14:15
Water soluble bases are stronger because both acids and base show their properties in water only.
1:29:40
X is stronger base as it has more PH
👍👍

[abhisheksnf]

1:16:18 water soluble bases are generally strong

35:07 Sodium zincate formed whend NaOH (base) reacts with Zn Metal

Bleaching agents, such as chlorine bleach, work by breaking down or altering the color molecules in a substance. The color in many materials, like fabrics or pigments, is often due to the presence of molecules that absorb and reflect specific wavelengths of light. Bleaching power is essentially the ability of a substance to remove or decolorize these molecules.

Here's a general explanation of how bleach works to remove color:

Oxidation: Bleaching agents are strong oxidizing agents. They introduce oxygen molecules into the color molecules of the substance being bleached.

Breaking Down Color Molecules: The oxygen molecules break the chemical bonds in the color molecules, altering their structure. This process makes the molecules less capable of absorbing and reflecting light, effectively reducing or eliminating the color.

Water and Salt Formation: In many cases, the color change is accompanied by the formation of water and salts. This is because the bleach not only breaks down the color molecules but also reacts with other components in the substance, forming new, colorless compounds.

It's important to note that not all substances respond to bleaching in the same way, and the effectiveness of bleach can depend on factors such as the type of material being treated and the specific bleach used. Additionally, excessive use of bleach may damage certain materials. Always follow product instructions and recommendations when using bleach for bleaching purposes.

Some less reactive metals do not react with the acids are silver, gold, platinum etc .

[niharika]

56:35 bases are not react with metal oxide.. because metal oxide is base. So, base is not react with base

33:07 with calcium, hydrogen gas is not formed !

[yyyftyfyhffm]

at 32:48 The reaction of metals such as magnesium (Mg) and calcium (Ca) with nitric acid (HNO₃) results in the formation of hydrogen gas (H₂). This reaction can be explained by the general reaction of metals with acids, but the specific details can vary depending on the metal and the acid involved.

The general reaction for the reaction of a metal (M) with an acid (HX) is:

M

HX
→
MX

H

M+HX→MX+H

In the case of magnesium reacting with nitric acid, the specific reaction is:

H

Mg+2HNO

→Mg(NO

And for calcium reacting with nitric acid:

Ca

HNO

Ca(NO

H

↑
Ca+2HNO

​
→Ca(NO

)

​
+H

The hydrogen gas is produced as a result of the reduction of nitric acid by the metal. Nitric acid (
HNO
3
HNO

​
) is a strong oxidizing agent and can undergo reduction reactions. In the case of magnesium and calcium, they act as reducing agents, and the nitric acid is reduced to nitrogen oxides (
NO

NO

​
and
NO

The balanced equation for the reaction of magnesium with nitric acid is:

Mg

Similarly, for calcium:

The liberated hydrogen gas (

In summary, the reaction between magnesium or calcium and nitric acid involves the reduction of nitric acid to nitrogen oxides with the simultaneous production of hydrogen gas.

[DotgamingX]

for making Hydrogen gas at home
Materials Needed:
- Aluminum foil
- Sodium hydroxide (lye)
- Water
- A glass or plastic container
- A balloon or plastic bag (optional, for collecting the gas)
- Gloves and safety goggles (for protection)
- A well-ventilated area (preferably outdoors)

[Mgysh]

Sir Gold silver metals are non reactive or less reactive than other metals so, they are not any reaction with acid but a strong mixture of acids aquaragia it is reactive with all metals gold, silver and platinum etc.
If I wrong please guide me❤❤

[deathshot]

From where should I get the ppt of this

[Karan]

Whenever I tried to study chemistry I found it a bouncer going off my head.But after learning with you sir I found it very easy and interesting.Thank you Aashu sir❤❤❤

[dimplerani]

Who Thinks Ashu Sir is king and best Teacher of Science ❤👇

[pradyumandhawan]

I was not well by the time this chapter was discussed in my school and u saved my marks sir
High respect for u 🙂🙂😁😁😁

[pragatiandpalak..]

Sir agr acids and bases ki define puche paper m toh second definition likhenge yaa first one hi

[gauripawar]

Sir 1:15:22 as we are talking about solubility in bases they should give oh- when dissolve not h+ ions as you accidentally said

[Techhack]

1:31:47


"X" is stronger Base

[AbhijitDeka-uf]

56:28 ANSWER :- No reaction occurs
Metal oxides are generally basic in nature. So when they react with bases no reaction occurs.
