boilng points would boil overAnswer:
Explanation:
Answer:
5.83 mol.
Explanation:
- From the balanced reaction:
<em>2Al + 3Ag₂S → 6Ag + Al₂S₃,</em>
It is clear that 2 mol of Al react with 3 mol of Ag₂S to produce 1 mol of Ag and 1 mol of Al₂S₃.
Al reacts with Ag₂S with (2: 3) molar ratio.
<em>So, 2.27 mol of Al reacts completely with 3.4 mol of Ag₂S with (2: 3) molar ratio.</em>
<em />
- The limiting reactant is Ag₂S.
- The excess "left over" reactant is Al.
The reamining moles of excess reactant "Al" = 8.1 mol - 2.27 mol = 5.83 mol.
Answer:
have lower boiling points than alcohols of similar molecular weights.
Explanation:
Alkenes are hydrocarbons of the general molecular formula CnH2n. Alkenes are nonpolar hydrocarbons that are insoluble in water.
We must recall that alcohols are able to associate in water due to hydrogen bonding. This causes alcohols to have a relatively higher boiling point than alkenes of comparable molecular weight. Hencethe answer above.
Carbon- 0.27/0.45 = 0.60*100 = 60%
Hydrogen- 0.020/0.45 = 0.04*100 = 4%
Oxygen- 0.16/0.45 = 0.36*100 = 36%
