[its_pranay]

17:05 Hetreginues two or more mixture but particles are not uniformly divided.

[Cookie.]

Because of dissolved gases and salt in sea water( there is no visible boundary of separation) it is classified as homogeneous mixture

[its_pranay]

15:33 Mixture because they have humus, compost, insect, leaves, etc....

[VishalPurohit-bcth]

Mam mind is saturated by your explanation 😂😂

[rimasingh]

A solution in which more solute can dissolve a given temperature is called an unsaturated solution

[aviop]

Thank u mam for giving masterpiece lecture 💙

[its_pranay]

14:02 For mixture example (on the screen) - lemon juice because it contains lemon juice, water, salt, sugar so yeah you know

[rimasingh]

They do not settled down when left and disturbed that is the collide quite stable

[anilgavadesir]

Thanks teacher for teaching so well ☺️☺️

[jitendrarai]

Ma'am you read very well, I liked it a lot

[joydebsaha]

Only thing I would say that byjus has got a speechless teacher😍😍

[its_pranay]

18:13 Sand and soil mixture is also hetrogeneous mixture

[जय_shree_Krishna]

Ma'am I have a doubt 🧐 please 🥺 solve it if compound is a homogeneous mixture then why we call it pure substance?
