Gravity that exists between two objects exists as a small force unless:
o one object's mass is much smaller than the other's
o the two objects are separated by a large distance
o one object's mass is much larger than the other's
the two objects are separated by a small distance

Okay this will take 1 hour okay dont forget me.

Determine the  wavelength of light emitted when an electron  in an li2+ ion  makes a transition from an orbital with n  =  6 to an orbital with n  = 5.

Just took the quiz on edgenuity and the correct answer is "c.  4.54 x  10–12  j"

  the volume of  0.220 m k2s    solution  required  to  completely  react with 175 ml  of 0.115m co(no3)2  calculate the moles  of co(no3)2 =  molarity x volume/1000175 x0.115/1000= 0.02  moleswrite  the reacting  equationk2s(aq)  +  co(no3)2  = 2 kno3(aq)  + cos(s)by  use  of mole ratio between k2s to co(no3)2 which  is  1: 1 the moles of k2s is therefore = 175  x0.115/1000= 0.02  molesvolume = moles/molarity=0.02/0.22=0.09  ml  of k2s
