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?

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.

But what is the reaction

@ridatanvir1822

Жыл бұрын

Ammonium hydroxide not chloride

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.

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.

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.

On the first one is it not nitric acid n ammonia hydroxide... correct me if I'm wrong

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

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!! 💙

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.
