In a famous experiment, Wöhler heated ‘inorganic’ ammonium cyanate in the absence of air. The only product of the reaction was ‘

organic’ urea, CO(NH2)2. No other products were formed in the reaction. What is the formula of the cyanate ion present in ammonium cyanate? A CNO– B CNO2– C CO– D NO– why A?

<span>CO(NH2)2 the only product consists of 1 Carbon 1 Oxygen , 2 Nitrogen and 4 Hydrogen We are heating Ammonium Cyanate, Ammonium Ion NH4+ NH4+ consists of 1 Nitrogen 4 Hydrogen. Compare the reactant decomposed and product formed.

There should be 2 Nitrogen so Cyanate must contain one Nitrogen atom, one Carbon and one oxygen.</span>

vampirchik [111]

Answer:

Explanation:

It depends on how this is done. If you raise the pressure, the nitrogen will disappear (liquify) and all that will be left will be the 21 % oxygen and the 1% argon.

The process is very complicated because the boiling point of nitrogen keeps on changing. The boiling point is unstable.

How many moles of S are in 35.4 g of (C3H5)2S?
alexandr402 [8]
<span>0.310 moles First, look up the atomic weights of the elements involved. Atomic weight carbon = 12.0107 Atomic weight hydrogen = 1.00794 Atomic weight sulfur = 32.065 Molar mass (C3H5)2S = 6 * 12.0107 + 10 * 1.00794 + 32.065 = 114.2086 g/mol Moles (C3H5)2S = 35.4 g / 114.2086 g/mol = 0.309959145 mol Since there's just one sulfur atom per (C3H5)2S molecule, the number of moles of sulfur will match the number of moles of (C3H5)2S which is 0.310 when rounded to 3 significant digits.</span>
