Calculate the ratio of h+  ions to oh–  ions at a ph  =  7. find the concentration of h+  ions to oh–  ions listed in table b of your student guide. then divide the h+  concentration by the oh–  concentration. record this calculated ratio in table a of your student guide.

compare your approximated and calculated ratios of h+  ions to oh–  ions at a ph  =  7. are they the same? why or why not? record your comparison in table a.

what is the concentration of h+  ions at a ph  =  7?

  mol/l 

what is the concentration of oh–  ions at a ph  =  7?

  mol/l  

what is the ratio of h+  ions to oh–  ions at a ph  =  7?

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

that the claims meet official rules.

don't misinterpret the claims
