Then it is about stoichiomtery which determines the reaction ?

Actually, I want to how the chemical reactions are written. Is it based on stoichiometry or atomic configuration or just by assumption, For eg. 2PbS + 3O2 → 2 PbO + 2SO2 PbS + 2O2 → PbSO4 look at these reactions they have same...

Thank you

Thank you all for clearing my doubt I find this forum very helpful and I am going to use it to clear all my doubts:wink::wink::wink::wink::wink:

I am really sorry I can't get you

Then the motion is relative,

I can understand you but how does the centripetal acceleration acts for person outside the space ship. In spaceship it is due to velocity with which it rotates. So will the person outside the spaceship will also have the same velocity?

For a Space ship, it revolve around the orbit due to the orbital velocity. But a man outside space. Is he moving at the same orbital velocity as the spaceship ??

Ok then, How astronauts float in outer space? is it due to zero gravity?

then why they didnt fall

Another Doubt Guys, I was watching this video on youtube. it is about weightlessness in space. it states that the astronauts inside a spaceship fly in space not due to zero gravity but due to centripetal force with which the satellite is revolving the earth. My question is "then why the...

OH! thank you, Dale

Thank you f95toli and Dale But Dale, I cannot get you precisely

Thank you for clearing my doubt, Master

I have been in my physics crash course for my entrance exam. I was looking at the chapter "Units and Measurement". I got a doubt in this chapter and I didn't get it cleared by my teacher. So I am posting this in this forum. We have 7 fundamental quantities and other quantities are derived...
