2. Calculate the mass of 2.4 moles of ammonia, NH3.
_grams

A student performing this reaction makes 8.5 grams of ammonia, NHz. How
many moles of ammonia did she make?
_moles

The se-ci  bonds is more polar  than s-br bond

Ibelieve the answer 4 moles

Ithink it’s carbon dioxide

  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
