Phoenix Blood What was your answer in the salmon thingy? Height constant or what?
Kaunsa salmon? Woh mota wala?
Less height, coz he's having more weight (more weight= more force, and since w=fd, force has increased, toh here you can see that force and distance are inversely proportional... :ROFLMAO:.. so.... if force has increased, the distance should decrease :sick:...)

idk, idk, wbu?

If u have dat gren book by christopher , open page 230 n read da table .it says wth water we get metal hydroxide
yes with water we get metal hydroxide
but this is with water at room temp
but if u heat water to boiling point u get water gas which is steam
if you reacted STEAM with metal u get metal oxide
