Top 3 questions answers-
1) The acid needed here is Nitric acid and the base needed here is Ammonium hydroxide.
The chemical reaction is-
HNO3 + NH4OH = NH4NO3 + H2O.
2) a) Vinegar contains acetic acid.
b) Milk contains lactic acid.
c) Tomatoes contain oxalic acid.
d) Apples contain malic acid.
3) Toothpaste is basic in nature. Our mouth contains many acids. We know that a base can neutralize an acid. In this case it becomes neutral and that's why Toothpaste help prevent decay teeth.
And another acid that tomatoes contain I think other than oxalic acid is citric acid since it is sour.
Sir would you please check my answers?
Posted 3 years ago but still it's fresh for 2021-22 batch like. Tq so much sir😊😊
Most welcome
Yes ❤️
True
Yeah!!!😉😂
@@curious__she hlo bhumika where r u from
1)hcl+naoh=n2naoh+h20 2)a) vinegar=acetic acid,milk-lactic acid,tomatoes- oxalic acid,apples- citrus acid 3) toothpaste contains salt which help neutralize the acids and bases presnt in the saliva. thats why brushing our teeth with toothpaste prevents decaying of teeth.
Army u proved us that we study too😁💜
1. Ammonium nitrate (NH4NO3) is indeed soluble in water. It is formed by the reaction between ammonium hydroxide (NH4OH) and nitric acid (HNO3).
2. Vinegar contains acetic acid, milk contains lactic acid, tomatoes contain oxalic acid, and apples contain malic acid. These acids contribute to the characteristic taste of the respective food items.
3. The bacteria living on the teeth and gums produce acid, which can erode the tooth enamel and cause dental decay. Fluorine, which is contained in toothpaste, neutralizes this acid and helps to prevent tooth decay.
Thanks you sir
1. Ammonium chloride(weak base)+ Nitric acid (strong acid)will give Ammonium nitrate(acidic salt)+ water. 2.(a)Acetic Acid,(b)Lactic Acid,(c)Oxalic Acid,(d)Malic Acid. 3.Toothpaste is actually basic in nature. So, it helps in removing the bacteria that is present in the teeth that contains acid. So, the toothpaste will neutralise the acid and helps in preventing tooth decay.
Ammonium+HNO3---> ammonum nitrat+ H2
But what is the reaction
Ammonium hydroxide not chloride
Tomato sauce has vinegar in it which is used in many materials like pickles as a preservative. Thus, tomato sauce has oxalic and acetic acid.
1.) Ammonium Hydroxide + Nitric Acid ----------> Ammonium Nitrate + Water + Heat
NH4OH + HNO3 ---------> NH4NO3 + H2O + Q
2.) a.) Vinegar isused in many materials like pickles as a preservative and has Acetic acid in it.
b.) Milk or curd has lactic acid in it
c.) Tomato sauce has Oxalic acid present in it
d.) Apples is mostly determined by the Malic acid present in it
3.) Major tooth issues like tooth decay is caused when we eat sugary foor such as chocolates, sweets, etc. The bacteria's act upon this sugar and transform it into acid because ( bacteria + sugar = acid ), and this acid eats up the tooth leading to tooth decay. As Toothpaste is a base, it prevents the acid from eating up the tooth by neutralizing it's effect. Hence, Toothpaste prevents tooth decay
1)HNO3 +NH3 = NH4NO
2) a) vinegar : acetic acid
b)milk : lactic acid
c)tomatoes : oxalic acid
d) apples : malic acid
3)When food particles decay in our teeth , the level of acidity in our mouth rises .This leads to tooth decay.
Toothpaste are basic to nature . So, this neutralizes the acids and help prevent tooth decay .
Sir very understandable. Please make more videos like this ...
On the first one is it not nitric acid n ammonia hydroxide... correct me if I'm wrong
1.Ammonium hydroxide+ nitric acid gives Ammonium nitrate and water.
NH4OH(aq)+ HNO3(aq) gives NH4NO3 +H2O.
2. Vinegar- Acetic acid, apple- malic acid
Milk- lactic acid, Tomatoes- oxalic acid
3. Bacteria present in our mouth break glucose and acid is formed, so; we use toothpaste which contains base that neutralize the acid.
Waah 👏👏👏👏👏
Sir excellent explanation.
And your answers are≈
(1)-Ammonia and Nitric acid.[HNO³+NH³--NH4NO]
(2)- -Vinegar~Acitic acid.
-Milk~Lactic acid.
-Tomato~Oxalic acid+Maleic acid.
-Apple~Maleic acid.
(3)-Because it contains Sodium fluoride (NaF). Which kills bacteria present on our teeth.
Thanks a lot sir.
Wow...thanks a lot sir! It helped me a lot
1. Nitric acid and ammonium hydroxide ---- HNO3+NH4OH----->NH4NO3+H2O
2.a) vinegar-acetic acid
b) milk-lactic acid
c) tomatoes-oxalic acid
d) apples-malic acid
3. Bacteria in your mouth causes tooth decay by changing the leftover food on our tooth into acids. These acids causes tooth decay. If we brush our teeth with toothpaste which is a base neutralizes the acid and hence tooth decay can be prevented.
Legends watching this in 2024 for the junior 10th😝😝
Yes am also.... 🤭🤗
Yes bruh 😅
Iam also
Yeah
True
1.Answer. nitric acidThe industrial production of ammonium nitrate entails the acid-base reaction of ammonia with nitric acid: HNO3 + NH3 → NH4NO. Ammonia is used in its anhydrous form (a gas) and the nitric acid is concentrated. The reaction is violent owing to its highly exothermic nature.
2.a)vinegar-acetic acid b) milk-lactic acid c)tomatoes-oxalic acid d) apple- malic acid
3.Toothpastes are basic in nature. They neutralise the effect of acids and thus prevent tooth from decaying.
Nice work.

The other acid that found in tomato is malic acid
HW:
1)The acid and a base formed are HNO3 and NH4Cl Respectively
2) vinegar - acetic acid
Milk - latic acid
Tomatoes - Oxalic acid
Apples- Malic acid
3) Toothpaste contains calcium fluoride and many other bases which is helpful to Neutralise our teeth and prevent from tooth decay :)❤
Acid present in Tomato is Oxalic acid😊
Number 1 question:
HNO3 + NH4CL= N2(NH4)+ CLNO3+ H2.😅 16:37
1.Ammonium nitrate as an acid , Nitric as base.
Therefore:NH4OH(aq) + HNO3(aq) = NH4 (s)+ H20 (L)
2. vinegar: acetic acid.
3. milk: lactic acid.
4. Tomato: oxalic acid.
5. Apple: malic acid.
(Q)3. Toothpaste contains sodium carbonate, which removes stains provide the foaming action and neutrolize an acid.
After the reaction it is ammonium nitrate NH4NO3
In my school my teacher also said this lesson but I didn't understood.But you said so clearly and now I understood this lesson.Thank you very much sir.

3)Tooth paste contain salt it neutrize acid and base so it help to prevent dacay ofteeth
This is how Chemistry 👨🔬 should be taught at school with complete practicals unlike the conventional means of reading the text :/
Thanks a lot Manocha Academy!! 💙
Sir, tooth decay happens because if a acid expected by germs and bacteria and toothpaste being a base neutralizes the reaction.
Sir, so amazingly explained that the concepts became very clear easily. Despite of being uploaded 4 yrs back, this video is still helpful and much relevant for the basic concept of this topic. Great work sir.👍🏻

Sir please do more videos on biology... It is helpful for competitive exams...
I got full marks seeing all your videos thanks a lot for helping 🙂 it's very interesting 😌
Great 👍
Actually,we eat the food which contains acids and if the acidic nature is more in our teeth it may cause tooth decay so we use the basic paste to neutrilize it
When pH value of mouth is below 5.5 bacteria present in mouth produce acid by degration of sugar and food particles remain in the mouth. The best way to prevent this to clean the mouth after eating food. Using toothpaste, which are generally basic neutralize the access acid and prevent tooth decay
They way he speaks is just like a ... infact I don't know what to call it. God bless you sir
Thanks for liking
Q1 ans: Ammonia and nitric acid are required to have salt ammonium nitrate
HNO3 + NH3=NH4NO3
Q2 ans: vinegar-acetic acid
apple-malic acid
milk-lactic acid
tomato-citric acid
Q3 ans: Acid is formed in our digestive system for digestion process the acid in our teeth may lead to damage in enamel
of the teeth and lead to decay of teeth , the toothpaste is a base it reacts with acid and neutralizes the acid so the toothpaste
helps in preventing decay of teeth...
Here are my answers to these questions hope to get response and if i m wrong please help me to find the correct answer..
Enjoyed this video too..
Thankyou sir..
Q3:when we don't wash our mouth after eating food particles settle down in our teeth.Some bacteria grow in that and produces acids. Toothpaste is a base which neutralises the acid and we can prevent tooth decay
🤚
1.HNO3(acid) + NH3(Base) = NH4NO(Salt)
2.a.Vinegar - acetic acid
b. Milk - lactic acid or lactate
c. Tomato - oxalic acid
. d. Apple - malic acid
3. The toothpaste (base) with fluroide helps to decay of teeths by preventing cavities, slow down the breakdown of enamel and speed up the remineralization process
And also the food we eat is acidic, the toothpaste neutralizes the acid to prevent tooth decay

2.Vinegar-Acetic acid CH3COOH
Milk-Lactic acid C3H6O3
Tomatoes-Oxalic acid
Apples-Malic acid
3.It helps to prevent decay of teeth from excess acid in our tooth by neutralizing it.
Since the reaction is between an acid and a base, it should produce salt and water right?
Shouldn't the acid be HNO3 and base NH4OH to produce NH4NO3 and H20
Still this video is gold for all of us
Thank you so much Sir

1 . Hydrocloric acid+sodium hydroxide=sodium chloride+H2O
2 . Vinegar = acetic acid
Tomatoes = oxalic acid
Apple= malic acid
Milk= lactic acid
3 . ★In our tooth there was some food particles were present it contains acid in nature. So the toothpaste is base in nature. So it will neutralize the acid.
Good one
Base is flouride

1: HNO3 + NH3 ➡️ NH4NO
2: a: acetic acid. b: Lactic acid c: oxalic acid d: Malic acid
3: Toothpaste have Flouride which prevent the decay of the teeth.
Apart from containing oxalic acid, Tomato ketchup also contains acetic acid to preserve it for a long time.
Q1)HNO3=acid
NH3=base
So,HNO3+NH3-----NH4NO3
Q2)a)vinegar-acetic acid
b)milk-lactic acid
c)Tomato-oxalic acid
d)apples-malic acid
Q3)Because toothpaste contains fluoride,fluoride fights against the bacteria present in our teeth and helps to prevent the decay in teeth
1)ammonium nitrate
NH3+HNO3=NH4NO3
Ammonia (base)+nitric acid (acid)
=ammonium nitrate
2)a)vinegar-acetic acid
B)milk-lactic acid
C)tomatoes-oxalic acid
D)apples-malic acid
3)when ph of mouth saliva falls below 5.5,the enamel gets weathered. Toothpastes which are generally basic are used for cleaning the teeth that can neutralize the excess acid and prevent tooth decay.
