Answer:
Option NH 3 is the correct answer.
Explanation:
A molecule which has hydrogen bonding will have the highest boiling point. So, out of the given options only NH 3 will have hydrogen bonding.
Whereas in CHCI 3 there will be dipole-dipole interactions and no hydrogen bonding within the molecule.
In OF 2 and C 6H 6, there will be dipole-dipole interaction in both the molecules.
Thus, we can conclude that NH 3 will have the highest boiling point.
Answer:
The correct answer is 0.52 moles.
Explanation:
Based on the given question, 37 grams of magnesium reacts with 38 grams of HCl to produce MgCl2 or magnesium chloride. The reaction is:
Mg (s) + 2HCl (aq) ⇒ MgCl2 (aq) + H2 (g)
There is a need to find the theoretical yield in moles of MgCl2. The formula for calculating the no. or moles is mass/molar mass. Therefore, moles of magnesium is 37/24 = 1.54 and moles of HCl will be 38/36.5 = 1.04.
From the reaction it is clear that one mole of magnesium reacts with two moles of HCl, as lesser quantity of HCl is present in the given case, therefore, HCl will be the limiting reagent.
Now theoretical moles of magnesium chloride will be,
= moles of HCl / 2
= 1.04 / 2
= 0.52 moles
An organic compound must meet the requirements of having both Carbon and Hydrogen bound to one another. As you can see, CO2 is the only compound that is not organic because it lacks hydrogen in it. All the other compounds have at least 4 Hydrogens and is the reason why they are an Organic Compound.
Explanation:
The combustion of ethanol is best represented by the equation below:
C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O + heat
Combustion process is very common among hydrocarbons.
Ethanol is an alcohol and in the presence of oxygen it will combust.
In combustion heat energy is always released into the environment.
C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O + heat
We see that ethanol combines with oxygen to give carbon dioxide and water in the reaction above.
The heat produced signifies that the reaction is exothermic in nature.
