Theory: Tin (II) Iodide is not a thermodynamically favored substance. What this means is that if you mix Tin and Iodine, nothing will happen. So Tin(II) chloride + Zinc(II) iodide is used instead to synthesize Tin(II) iodide. Can I have an explanation of why this is? I am looking at the reduction potentials and it seems the reaction is spontaneous however, so I am confused.
A sample of an unkown compound was analyzed and was found to contain 0.178 moles of tin and 0.712 moles of chlorine. What is the formula of the compound?
It is found experimentally that a compound composed only of iron and chlorine. A sample of this compound is composed of 2.470 g of iron and 4.703 g of chlorine. What is the empirical formula for this compound? (3 points)
a combustion analysis of a 0.2104 g hydrocarbon sample (containing only hydrogen and carbon) yielded 0.6373 g carbon dioxide and 0.3259 g water. A separate experiment determined that the molecular weight of this compound is 58.7 g mol-1. from this data, determine both emperical and the molecular formula of this substance.
