Answer : The molecular weight of this compound is 891.10 g/mol
Explanation : Given,
Mass of compound = 12.70 g
Mass of ethanol = 216.5 g
Formula used :
![\Delta T_f=i\times K_f\times m\\\\T_f^o-T_f=i\times T_f\times\frac{\text{Mass of compound}\times 1000}{\text{Molar mass of compound}\times \text{Mass of ethanol}}](https://tex.z-dn.net/?f=%5CDelta%20T_f%3Di%5Ctimes%20K_f%5Ctimes%20m%5C%5C%5C%5CT_f%5Eo-T_f%3Di%5Ctimes%20T_f%5Ctimes%5Cfrac%7B%5Ctext%7BMass%20of%20compound%7D%5Ctimes%201000%7D%7B%5Ctext%7BMolar%20mass%20of%20compound%7D%5Ctimes%20%5Ctext%7BMass%20of%20ethanol%7D%7D)
where,
= change in freezing point
= temperature of pure ethanol = ![-117.300^oC](https://tex.z-dn.net/?f=-117.300%5EoC)
= temperature of solution = ![-117.431^oC](https://tex.z-dn.net/?f=-117.431%5EoC)
= freezing point constant of ethanol = ![1.99^oC/m](https://tex.z-dn.net/?f=1.99%5EoC%2Fm)
i = van't hoff factor = 1 (for non-electrolyte)
m = molality
Now put all the given values in this formula, we get
![(-117.300)-(-117.431)=1\times 1.99^oC/m\times \frac{12.70g\times 1000}{\text{Molar mass of compound}\times 216.5g}](https://tex.z-dn.net/?f=%28-117.300%29-%28-117.431%29%3D1%5Ctimes%201.99%5EoC%2Fm%5Ctimes%20%5Cfrac%7B12.70g%5Ctimes%201000%7D%7B%5Ctext%7BMolar%20mass%20of%20compound%7D%5Ctimes%20216.5g%7D)
![\text{Molar mass of compound}=891.10g/mol](https://tex.z-dn.net/?f=%5Ctext%7BMolar%20mass%20of%20compound%7D%3D891.10g%2Fmol)
Therefore, the molecular weight of this compound is 891.10 g/mol
A fusion reaction can be regarded as the type of reaction that occurs where two lighter elements come together in a type of reaction giving rise to a heavier/more massive element.
A fusion reaction always creates a more massive atomic nucleus (option c).
When the two lighter nuclei comes together in a reaction, a more heavier/massive nucleus is formed but its mass will still be less than the combined mass of the two reactant nuclei.
This also indicates that the left over mass may have been released as energy.

Answer:
2.5 mole O2 should react (2 * 2.5) = 5.0 mole H2 but there is 6.0 mole H2. H2 remain in excess. O2 is the limiting reactant. mole of H2O formed = 2 * 2.5 = 5.0 mole.
