In this Mission Mid-Terms series, your favourite BYJU’S educator, Kriti Ma’am, revises all the important concepts in your class 10 Science Chapter 1 Chemical Reactions and Equations.

Some of the topics discussed in this class are as follows:
- Balanced Chemical Equations
- Types of Chemical Reactions
- Double Displacement Reaction
- Oxidation and Reduction

A complete chemical equation indicates the products, the reactants and their physical states symbolically. A chemical equation is balanced such that the number of atoms of each type in a chemical reaction is the same on the reactant and product sides of the equation as well. Moreover, the chemical equations must always be balanced. Join this class to learn in detail about Chemical Reactions and Equations.

Rancidity can be prevented using the following methods:
- Adding antioxidants (substances that prevent oxidation) to food.
- Storing food in airtight containers to slow the process of rancidification.
- Refrigerating food also helps to slow down rancidification.
- Replacing oxygen in the containers with another gas.
For example, to prevent chips from turning rancid, chips manufacturers flush the bags with nitrogen gas.

[virendersingh]

By coating iron with some grease or paint this will prevent rusting and this process is know as galvanization

[ManojGupta-gygb]

Ways to prevent from rancidity - antioxidants, refrigerator, nitrogen and helium gas, add antioxidants First to answer

[ManjunathManju-dekr]

Why are you talking too much in video of first 20 second

[vaibhavimahipathi]

Rancidity can be prevented using the following methods:
Adding antioxidants to food.
Storing food in airtight containers.
Refrigerating food.
Replacing oxygen in the containers with another gas.

[dtkpgangstergaming]

Refrigerated Products: Some refrigerated products, such as flaxseed oil or fish oil supplements, are stored in the refrigerator to slow down oxidation and extend their shelf life, preventing rancidity.

1.Apply oil paint on iron
2.Coating Iron or steel with zinc :gal animation
We can also prevent rusting of iron by anodising or making alloys

[dwarakanights]

THANK YOU SO MUCH MAAM FOR THIS WONDERFUL SESSION. I AM NEW 10TH GRADER OF YOURS

[rithizx]

Methods to prevent rancidity like Antioxidant and adding nitrogen gas to the chips and some other food items ❤

[muskanjaiswal]

HOMEWORK QUESTION (SOLUTION):
METHODS TO PREVENT
1. Adding Antioxidants.
2. Storing Food In Air Tight Containers.
3. Keeping The Food In Refrigerator.
4. Flushing NITROGEN Gas With The Food.

THANKS MA'AM ❤😊LOVED THE SESSION🤩🤩

[SamarthSanyal-vh]

Ma'am how do we balance C2H2+O2--> CO2+H2O

[SANS]

For combination reaction
H(S) + O2 (G) = H20 (AQ)

[Kristina_]

HOMEWORK QUESTIONS ANSWER
USING ANTI-OXIDANTS SUCH AS
NITROGEN IN CHIPS BAGS
BUTYLATED HYDROXY ANISOLE
BUTYLATED HYDROXY TOLUENE
AND BY STORING FOOD IN AIR-TIGHT ENVIRONMENT
THANK YOU SO MUCH FOR THE SESSION.

Is salt solution necessary for displacement reactions?

[lonesameer]

Mass can neither be created nor destroyed
