Answer:
802.2 K
Explanation:
To solve this problem we can use the formula:
Where Tb is the boiling point (in K).
We already know the values of both ΔHvap and ΔSvap, so we calculate Tb:
- ΔHvap = 47.45 kJ·mol⁻¹ = 47.45x10³J·mol⁻¹
Tb = 47.45x10³J·mol⁻¹/59.15 J·mol⁻¹·K⁻¹
So the boiling point of the compound is 802.2 K (or 529 °C)
100% bevause the capital T dominates always
If it's an endothermic reaction, then that means heat is being added to the system therefore H>0. Entropy is disorder, and since there are more moles on the products side, entropy is increasing therefore S>0 as well.
Answer:
a. 2.49
Explanation:
Molar mass of HCl= 36.46 g
So, no. of moles=418.8/36.46=11.48
Molality= no. of moles/mass of solvent= 11.48/4.62= 2.49
I believe that the best answer among the choices provided by the question is <span>he shape of molecules the three dimensional shape or configuration of a molecule is an important characteristic. this shape is dependent on the preferred spatial orientation of covalent bonds to atoms having two or more bonding partners.</span>
