Answer:
Propane
Explanation:
From the question given, we were told that 0.1240 kg of propane reacted with excess oxygen to produce 0.3110kg of carbon dioxide.
Since the reaction took place in the presence of excess oxygen, therefore, propane is the limiting reactant as all of it is used up in the presence of excess oxygen.
Answer:
Firstly, We have to convert it in the Miles formula...
No. of moles = Mass given/Molar Mass

Cations are formed by losing electrons in the valence shell of atoms. There are more protons than electron ions making the atom more positive.

The correct answer is :
the purpose of heating the mixture is to accelerate the reaction and mix the reagent.
The explanation:
Many organic reactions are slow and can take an extended period of time to achieve any noticeable effect so heating is often used to increase the rate of reaction. However, many organic compounds have low boiling points and will vaporise upon exposure to such high heat, preventing the reaction from proceeding in full.
so, heating is used. This refers to heating a solution with an attached condenser to prevent reagents from escaping
