3. The Solar Nebula Theory states that the Sun and all objects in the Solar System were formed when a cloud of gas and dust (a nebula) collapsed. What observational
evidence supports this theory?
a. Most of the icy objects are located closer to the Sun than Jupiter
b. The inclination of the orbits is larger for objects near the Sun than for far away
objects
C. Most objects have orbits that are highly elliptical
d. Most objects orbit in the same direction

Answer///precipitate;

Ithink it's the third answer

  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
