[Co(H2O)6](NO3)2 + NH3 + (NH4)2CO3 + H2O2 = [Co(NH3)4CO3]NO3 + NH4NO3 + H2O Calculate the theoretical yield of your product assuming you used: 4.8g (NH4)CO3 in 10ml H2O; 10ml 15 M NH3; 2.5g of Co(NO3)2 * 6H2O in 5ml H2O; 1.5 ml of 30% H2O2 (the density of 30% H2O2 is 1.11g/ml)

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

sure im new too!
