9:11 sir the reaction is wrong it should be calcium hydroxide + hydrochloric acid ---> water and calcium chloride salt Which concludes that metal Hydroxide +acid gives water + salt
Chemistry is just Amazing to read if you read it with full Interest. For those students who were not able to understand NCERT language. I will suggest you Schand books to prefer. They're written in a very Easy language really!!
Me abhi class 11 me hu or Mene bhai ki is series ko follow kra tha 2022-2023 batch me or board me adhe question idhar se hi aaye the…you can blindly follow him❤❤
well i have been getting into chemistry a lot, in 8th science was my favourite subject by ninth due to boring biology and physics i didn’t like science but biology was still my favourite and chemistry was also good now it’s been almost a month since my class 10th started and it’s safe to say that i love chemistry and i find it really ez but somewhere i had a doubt that which colours are the elements and stuff and how can we know them. I am sure school will teach it cuz it’s early but i still clicked this video and let’s see if this is good and cleared my doubts btw i love ur content, it has given me a idea of 10th since the beginning and all the steps for mastering ❤
