Analyze One of your classmates draws an electron dot diagram for a helium atom
with two dots. He tells you that these
dots mean each helium atom has two
unpaired electrons and can gain, lose,
or share electrons to have four pairs of
valence electrons and become stable. What
is wrong with your classmate's argument?

At a certain temperature the rate of this reaction is first order in hi with a rate constant of : 0.0632s2hig=h2g+i2g suppose a vessel contains hi at a concentration of 1.28m . calculate how long it takes for the concentration of hi to decrease to 17.0% of its initial value. you may assume no other reaction is important. round your answer to 2 significant digits.
