Nuclear fusion in the sun involves hydrogen (h) atoms combining to form helium (he). a student claims that since the atmosphere contains hydrogen, any fusion reaction on earth would result in an uncontrolled chain reaction. what is wrong with the student's reasoning? the hydrogen in air is not densely packed enough for an uncontrolled chain reaction. uncontrolled chain reactions can only happen during nuclear fission. it is impossible to cause a fusion reaction to happen anywhere outside of the sun. we are safe because there is no radioactive hydrogen in the air.
c.ocean winds can carry moisture with them and can bring rain and fog over inland areas
in acid base titration an acid neutralized by a base or a base is neutralized by acid (both are neutralized by each other).
one common reaction is
in titration we fill burette with either acid or base and and take other in flask.
when we start adding solution from burette to flask, neutralization starts. at the ponint of complete neutrlization all the acid / base neutralized base /acid.
this point is when the content of flask or beaker consists of only water, salt and trace of indicator
thus answer is point of neutralization.
